(4) Can they be combined? \u2014 Yes: collagen stimulators fill depressions while Rejuran cultivates the whole face \u2014 but physician planning is needed to avoid overstimulation. (5) Cost differences \u2014 Rejuran requires multiple sessions (lower per-session cost, total depends on count); collagen stimulators cost more per session but last longer.

When will I see results?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Result timeline: (1) Immediate after one session \u2014 skin looks dewy thanks to micro-trauma stimulation and the hydrating repair mask (partly temporary).

Rappoel Dermatology offers Rejuran \u2014 Korea’s PN regenerative injection that rebuilds skin quality from the dermis<\/div>\n<\/p><\/div>\n<p>Rejuran (also called the ‘baby injection’) is Korea’s signature skin-regeneration procedure \u2014 a favorite maintenance treatment among many Korean celebrities and dermatologists themselves. Common skin-quality concerns share an underlying theme of ‘compromised skin barrier plus dermal aging’: (1) Repeated dryness and flaking \u2014 weak barrier function means skincare cannot retain moisture. (2) Enlarged pores \u2014 collagen loss and sebum imbalance weaken the support around pores, making them look larger. (3) Fine lines and roughness \u2014 reduced dermal collagen and elastin fibers coarsen skin texture and create fine lines. (4) Redness and sensitivity \u2014 after barrier damage, external irritants easily trigger flushing and stinging. (5) Acne scars and uneven pigmentation \u2014 weakened repair capacity after inflammation. Rejuran’s core ingredient is PN (Polynucleotide) \u2014 DNA fragments extracted from salmon sperm that, when injected into the dermis, activate fibroblast activity, stimulate collagen and elastin regeneration, and repair damaged skin tissue \u2014 upgrading from ‘surface hydration’ to ‘dermal repair and regeneration.’ Rappoel Dermatology near Gangnam Station, Seoul, provides Rejuran treatment.<\/p>\n<h2>Technical Principles of Rejuran<\/h2>\n<ul>\n<li><strong>PN polynucleotide core:<\/strong> PN is a highly purified DNA fragment from salmon sperm \u2014 structurally compatible with human DNA; once injected, it acts as a ‘cell repair signal’ activating fibroblasts to promote new collagen and elastin<\/li>\n<li><strong>Direct dermal injection:<\/strong> Ultra-fine needles deliver PN straight into the dermis \u2014 reaching the root of the problem (rather than staying in the surface stratum corneum) for more direct repair<\/li>\n<li><strong>Skin barrier restoration:<\/strong> PN promotes epidermal cell regeneration and intercellular lipid synthesis \u2014 once the barrier recovers, moisture retention improves and redness and sensitivity decrease<\/li>\n<li><strong>Collagen renewal and texture remodeling:<\/strong> Cumulative treatment stimulates collagen production \u2014 support around pores recovers, skin thickness increases, and texture refines<\/li>\n<li><strong>Anti-inflammatory and repair modulation:<\/strong> PN has anti-inflammatory properties that modulate inflammation in damaged skin \u2014 especially helpful for redness and the healing phase of acne scars<\/li>\n<\/ul>\n<h2>Common Rejuran Treatment Protocols<\/h2>\n<ul>\n<li><strong>Full-face foundational care (3 sessions advised):<\/strong> Full-face PN injection \u2014 improving overall texture, pores, and radiance.

Unsuitable or cautious: (1) pregnancy and breastfeeding (postpone \u2014 insufficient safety data); (2) active infection, severe acne, or skin disease in the area (treat first); (3) severe allergy to fish or DNA components (physician assessment); (4) autoimmune disease or immunosuppressant use (physician assessment); (5) bleeding disorders or anticoagulant use (evaluation needed); (6) severely aged skin expecting ‘one-session transformation’ \u2014 Rejuran accumulates over sessions and requires patience to complete the full course.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long is the recovery after Rejuran? Will it be red or bruised?<\/div>\n<div class=\"faq-a\">Recovery timeline: (1) At injection \u2014 skin flushes and warms (sunburn-like); puncture marks are tiny (mostly ultra-fine needles or cannulas). (2) Day 1 \u2014 the peak of redness and swelling; avoid makeup that day and boost moisturizing repair; a few have small bruises at puncture points. (3) Days 2-3 \u2014 redness clearly subsides; most resume normal makeup and social life (some still slightly flushed). (4) Days 4-7 \u2014 skin returns to normal, and you begin to feel finer texture. (5) Weeks 2-4 \u2014 collagen renewal kicks in; texture improvement (glow, pores) becomes increasingly visible. (6) Bruising \u2014 small red dots at puncture sites are common but tiny, concealable with makeup, fading in 5-7 days; extent depends on constitution and physician technique. (7) Care notes \u2014 avoid exfoliation, acid peels, saunas, strenuous exercise, and sun exposure for 1 week (boost sun protection); avoid irritating skincare. (8) Social planning \u2014 most return to normal social life in 2-3 days; reserve a week before major events.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can Rejuran be combined with other treatments?<\/div>\n<div class=\"faq-a\">Combination strategies: (1) Rejuran plus skin booster \u2014 the classic combo: PN repair and regeneration plus HA deep hydration, solving ‘repair and hydration’ together \u2014 common in Korean dermatology. (2) Rejuran plus pico\/carbon laser \u2014 the laser first handles pigmentation or pores; Rejuran then accelerates skin regeneration during the healing phase, lowering hyperpigmentation and dryness risk \u2014 a complete destroy-then-repair cycle. (3) Rejuran plus botox \u2014 botox relaxes dynamic lines while Rejuran improves static texture \u2014 comprehensive handling of dynamic and static wrinkles. (4) Rejuran plus Thermage\/ultrasound lifting \u2014 devices stimulate deep collagen contraction and remodeling while Rejuran supplies superficial repair nutrients \u2014 deep and superficial anti-aging in combination. (5) Rejuran plus HA filler \u2014 filler addresses local volume deficits while Rejuran improves overall skin quality \u2014 combining points and surface. (6) Sequencing \u2014 most combinations can be done in the same session or 1-2 weeks apart as the physician plans; Rappoel offers personalized ‘skin management programs’ planned in one visit.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">What is the difference between Rejuran and collagen-stimulating fillers like Sculptra?<\/div>\n<div class=\"faq-a\">Ingredient comparison: (1) Rejuran (PN) \u2014 salmon DNA polynucleotide: promotes fibroblast activity and collagen renewal and repairs the barrier; focused on ‘improving skin quality’ with gradual, natural results requiring multiple sessions \u2014 Korea’s national-level maintenance injection. (2) Collagen-stimulating fillers (PLLA\/PCL types) \u2014 poly-L-lactic acid or polycaprolactone microparticles: injected to trigger collagen encapsulation and growth, mainly for ‘filling depressions and volume’ \u2014 used for temples, nasolabial folds, and cheek hollows, with results lasting 1-2+ years. (3) Core difference \u2014 Rejuran is ‘whole-face skin cultivation’ (texture, pores, barrier, fine lines); these fillers are ‘localized volume restoration’ \u2014 different purposes and injection planes. (4) Can they be combined? \u2014 Yes: collagen stimulators fill depressions while Rejuran cultivates the whole face \u2014 but physician planning is needed to avoid overstimulation. (5) Cost differences \u2014 Rejuran requires multiple sessions (lower per-session cost, total depends on count); collagen stimulators cost more per session but last longer. (6) Rappoel recommends the best component combination based on whether your main concern is ‘skin quality’ or ‘volume loss.’<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will one Rejuran session improve my skin? When will I see results?<\/div>\n<div class=\"faq-a\">Result timeline: (1) Immediate after one session \u2014 skin looks dewy thanks to micro-trauma stimulation and the hydrating repair mask (partly temporary). (2) Weeks 1-2 \u2014 the barrier starts repairing; hydration and radiance improve and redness lessens. (3) Weeks 2-4 \u2014 collagen renewal begins; pores and skin feel start improving \u2014 the main perceivable effect of a single session. (4) After session 3 (about 3 months) \u2014 collagen accumulation reaches a tipping point \u2014 pores, fine lines, thickness, and elasticity show clear, stable improvement. (5) Maintenance \u2014 improvements persist for 6-12 months after the full course, gradually returning with natural aging. (6) Honest note \u2014 Rejuran is not a ‘one-shot skin swap’ magic but the science of ‘cumulative cultivation’; clear transformation requires completing the recommended course \u2014 Rappoel plans with a course mindset, not one-off sales. (7) Lifestyle support \u2014 adequate sleep, sun protection, and basic moisturizing amplify Rejuran’s results.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Large pores and fine lines aging your skin?

How is it different from a skin booster (water injection)?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Core differences: (1) Rejuran's ingredient \u2014 PN polynucleotide (salmon DNA fragments) works on 'repair and regeneration': activating fibroblasts, promoting collagen and elastin renewal, and repairing the skin barrier \u2014 addressing structural skin-quality problems. (2) Skin booster's ingredient \u2014 mainly HA for 'deep hydration': locking moisture in the dermis for a dewy, luminous look \u2014 addressing dehydration. (3) Analogy \u2014 a skin booster is 'watering the skin,' while Rejuran is 'fertilizing and rebuilding the soil' \u2014 the former hydrates, the latter cultivates. (4) Result differences \u2014 skin booster gives an immediate dewy glow (1-3 months); Rejuran needs cumulative sessions and improves 'constitutional' issues like pores, texture, thickness, and barrier \u2014 with longer-lasting results. (5) In practice \u2014 Korean dermatology commonly combines both (Rejuran plus HA) for the synergistic effect of 'repair plus hydration.' (6) Rappoel recommends the best plan based on your main concern (dullness and dehydration \u2192 skin booster; pores, fine lines, barrier \u2192 Rejuran or both).\"}}, {\"@type\": \"Question\", \"name\": \"Is Rejuran safe? What is the ingredient? Are there side effects?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Safety explained: (1) Ingredient source \u2014 PN is DNA purified from salmon sperm, highly processed to remove protein impurities \u2014 structurally similar to human DNA with good biocompatibility; approved for years by Korea's MFDS and used in many countries as a mature ingredient. (2) Allergy risk \u2014 theoretically those allergic to fish should be cautious; purified PN contains no allergenic proteins, and actual allergic reactions are extremely rare; Rappoel asks about allergy history before injection. (3) Common side effects \u2014 redness, mild bruising at puncture points, and small papules in some \u2014 usually fading within 2-5 days. (4) Rare side effects \u2014 infection (extremely rare with sterile technique) and nodules (possible with over-superficial high-volume injection; experienced physicians avoid this). (5) Safety advantage \u2014 PN is not a foreign filler and is naturally metabolized by the body; it contains no cross-linkers and has a strong long-term safety record. (6) Rappoel uses authentic certified Rejuran products, sterile technique, and experienced physicians for a safe procedure.\"}}, {\"@type\": \"Question\", \"name\": \"Does Rejuran hurt? Is anesthesia used?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Pain experience: (1) Sensation \u2014 full-face multi-point injection with varying sensitivity by zone: forehead and cheeks are less sensitive; eye and lip areas more so; most describe 'mild stinging and soreness.' (2) Anesthesia \u2014 20 minutes of topical cream is standard and greatly reduces discomfort; sensitive patients can discuss stronger anesthesia. (3) Duration \u2014 the actual injection takes 15-20 minutes across dozens to hundreds of points \u2014 a 'cumulative micro-sting' rather than one sharp pain. (4) After \u2014 skin feels flushed and warm (like mild sunburn), fading within hours to 1-2 days; a few have mild swelling. (5) Tolerance \u2014 most complete it comfortably under topical anesthesia; pain-sensitive patients may opt for staged sessions or added soothing measures. (6) Rappoel prioritizes comfort \u2014 adequate anesthesia, fine needles, and smooth technique keep the procedure as easy as possible.\"}}, {\"@type\": \"Question\", \"name\": \"How many Rejuran sessions do I need? How often?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Session count explained: (1) Single session \u2014 one session already improves texture (radiance and hydration), but 'constitutional' improvements (pores, texture, thickness) require accumulation. (2) Recommended course \u2014 a full course is usually 3 sessions (every 3-4 weeks); by session 3, collagen renewal accumulates into clear, stable skin-quality improvement. (3) Maintenance \u2014 after a full course, a session every 3-6 months maintains results \u2014 skin maintenance is a 'long-term investment' like fitness. (4) Timeline \u2014 noticeable at 2-4 weeks after session 1 (glow and hydration); pores, fine lines, and thickness improve clearly after sessions 2-3; results last 6-12 months after the course. (5) By condition \u2014 young or mildly troubled skin may feel clear improvement after 2 sessions; visibly aged or severely damaged skin may need 4-5. (6) Rappoel plans personalized courses \u2014 assessing skin first, then advising the best number and interval of sessions.\"}}, {\"@type\": \"Question\", \"name\": \"How much does Rejuran cost? How is it priced?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Cost explained: (1) Pricing \u2014 Rejuran is priced by 'formulation plus treatment area' (e.g., full face, full face plus neck, focused boosting); different versions (standard\/enhanced) have different prices. (2) Price range \u2014 Korea is Rejuran's home country, so prices are friendlier than elsewhere; Rappoel offers reasonable transparent pricing quoted after consultation. (3) Factors \u2014 formulation, treatment area, whether combined with a skin booster or other treatments, and clinic promotions. (4) Course pricing \u2014 a full 3-session course usually comes with package discounts, more economical than single sessions. (5) Value comparison \u2014 versus spending on high-priced skincare with limited results, Rejuran directly improves skin structure from the dermis \u2014 more efficient as a 'course mindset' investment. (6) Rappoel's principle \u2014 no pushing of unnecessary sessions; planning based on actual skin needs; for detailed pricing, book a free consultation.\"}}, {\"@type\": \"Question\", \"name\": \"Who is suitable for Rejuran?

Rappoel Dermatology offers Rejuran \u2014 Korea’s PN regenerative injection that rebuilds skin quality from the dermis<\/div>\n<\/p><\/div>\n<p>Rejuran (also called the ‘baby injection’) is Korea’s signature skin-regeneration procedure \u2014 a favorite maintenance treatment among many Korean celebrities and dermatologists themselves. Common skin-quality concerns share an underlying theme of ‘compromised skin barrier plus dermal aging’: (1) Repeated dryness and flaking \u2014 weak barrier function means skincare cannot retain moisture. (2) Enlarged pores \u2014 collagen loss and sebum imbalance weaken the support around pores, making them look larger. (3) Fine lines and roughness \u2014 reduced dermal collagen and elastin fibers coarsen skin texture and create fine lines. (4) Redness and sensitivity \u2014 after barrier damage, external irritants easily trigger flushing and stinging. (5) Acne scars and uneven pigmentation \u2014 weakened repair capacity after inflammation. Rejuran’s core ingredient is PN (Polynucleotide) \u2014 DNA fragments extracted from salmon sperm that, when injected into the dermis, activate fibroblast activity, stimulate collagen and elastin regeneration, and repair damaged skin tissue \u2014 upgrading from ‘surface hydration’ to ‘dermal repair and regeneration.’ Rappoel Dermatology near Gangnam Station, Seoul, provides Rejuran treatment.<\/p>\n<h2>Technical Principles of Rejuran<\/h2>\n<ul>\n<li><strong>PN polynucleotide core:<\/strong> PN is a highly purified DNA fragment from salmon sperm \u2014 structurally compatible with human DNA; once injected, it acts as a ‘cell repair signal’ activating fibroblasts to promote new collagen and elastin<\/li>\n<li><strong>Direct dermal injection:<\/strong> Ultra-fine needles deliver PN straight into the dermis \u2014 reaching the root of the problem (rather than staying in the surface stratum corneum) for more direct repair<\/li>\n<li><strong>Skin barrier restoration:<\/strong> PN promotes epidermal cell regeneration and intercellular lipid synthesis \u2014 once the barrier recovers, moisture retention improves and redness and sensitivity decrease<\/li>\n<li><strong>Collagen renewal and texture remodeling:<\/strong> Cumulative treatment stimulates collagen production \u2014 support around pores recovers, skin thickness increases, and texture refines<\/li>\n<li><strong>Anti-inflammatory and repair modulation:<\/strong> PN has anti-inflammatory properties that modulate inflammation in damaged skin \u2014 especially helpful for redness and the healing phase of acne scars<\/li>\n<\/ul>\n<h2>Common Rejuran Treatment Protocols<\/h2>\n<ul>\n<li><strong>Full-face foundational care (3 sessions advised):<\/strong> Full-face PN injection \u2014 improving overall texture, pores, and radiance. Strategy: every 3-4 weeks, 3 sessions complete a full course, then a maintenance session every 3-6 months<\/li>\n<li><strong>Focused boosting (eye area\/neck):<\/strong> Intensified injection for localized aging zones like eye-area fine lines and neck lines. Strategy: ultra-fine needles or device-assisted delivery to improve local wrinkles<\/li>\n<li><strong>Rejuran plus skin booster (mesotherapy):<\/strong> PN regeneration plus HA deep hydration \u2014 a ‘repair first, then hydrate’ full skincare combination. Strategy: same session or alternating (common in Korean dermatology)<\/li>\n<li><strong>Rejuran after laser (post-treatment repair):<\/strong> Skin is in a healing phase after laser \u2014 PN accelerates repair and reduces hyperpigmentation risk. Strategy: PN at 2-4 weeks after laser<\/li>\n<li><strong>Different Rejuran formulations:<\/strong> Selecting the suitable version by skin condition (e.g., enhanced formulas with higher PN concentration or additional components). Strategy: physician assesses skin and chooses at consultation<\/li>\n<\/ul>\n<h2>Rappoel Rejuran Protocol<\/h2>\n<ol>\n<li><strong>Consultation and skin assessment (5 min):<\/strong> Review skin issues (pores\/fine lines\/redness\/dryness) \u2192 confirm barrier state \u2192 discuss expectations \u2192 plan the number of sessions<\/li>\n<li><strong>Cleansing and anesthesia (20 min):<\/strong> Makeup removal \u2192 topical anesthetic cream for 20 minutes (full-face injection needs adequate anesthesia for comfort)<\/li>\n<li><strong>PN injection (15-20 min):<\/strong> Point or linear injections into the dermis with ultra-fine needles \u2192 even full-face coverage \u2192 physician adjusts depth and density by skin condition (reduced in sensitive zones)<\/li>\n<li><strong>Soothing (5 min):<\/strong> Calming mask or ice pack to ease redness and swelling \u2192 apply repair skincare<\/li>\n<li><strong>Post-care instructions (2 min):<\/strong> No makeup or water contact that day (depending on puncture marks) \u2192 normal skincare and makeup after 24-48 hours \u2192 boost moisture and sun protection for 1 week, avoid exfoliation and sauna \u2192 next session in 3-4 weeks<\/li>\n<\/ol>\n<p>A Rejuran session takes about 30-40 minutes (including anesthesia); you can apply makeup normally the next day, texture improvement appears within 2-4 weeks, and a full course (3 sessions) lasts 6-12 months. Located 3 minutes from Gangnam Station Exit 10, with seamless English and Chinese consultation.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">What is Rejuran? How is it different from a skin booster (water injection)?<\/div>\n<div class=\"faq-a\">Core differences: (1) Rejuran’s ingredient \u2014 PN polynucleotide (salmon DNA fragments) works on ‘repair and regeneration’: activating fibroblasts, promoting collagen and elastin renewal, and repairing the skin barrier \u2014 addressing structural skin-quality problems. (2) Skin booster’s ingredient \u2014 mainly HA for ‘deep hydration’: locking moisture in the dermis for a dewy, luminous look \u2014 addressing dehydration. (3) Analogy \u2014 a skin booster is ‘watering the skin,’ while Rejuran is ‘fertilizing and rebuilding the soil’ \u2014 the former hydrates, the latter cultivates. (4) Result differences \u2014 skin booster gives an immediate dewy glow (1-3 months); Rejuran needs cumulative sessions and improves ‘constitutional’ issues like pores, texture, thickness, and barrier \u2014 with longer-lasting results. (5) In practice \u2014 Korean dermatology commonly combines both (Rejuran plus HA) for the synergistic effect of ‘repair plus hydration.’ (6) Rappoel recommends the best plan based on your main concern (dullness and dehydration \u2192 skin booster; pores, fine lines, barrier \u2192 Rejuran or both).<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is Rejuran safe? What is the ingredient? Are there side effects?<\/div>\n<div class=\"faq-a\">Safety explained: (1) Ingredient source \u2014 PN is DNA purified from salmon sperm, highly processed to remove protein impurities \u2014 structurally similar to human DNA with good biocompatibility; approved for years by Korea’s MFDS and used in many countries as a mature ingredient. (2) Allergy risk \u2014 theoretically those allergic to fish should be cautious; purified PN contains no allergenic proteins, and actual allergic reactions are extremely rare; Rappoel asks about allergy history before injection. (3) Common side effects \u2014 redness, mild bruising at puncture points, and small papules in some \u2014 usually fading within 2-5 days. (4) Rare side effects \u2014 infection (extremely rare with sterile technique) and nodules (possible with over-superficial high-volume injection; experienced physicians avoid this). (5) Safety advantage \u2014 PN is not a foreign filler and is naturally metabolized by the body; it contains no cross-linkers and has a strong long-term safety record. (6) Rappoel uses authentic certified Rejuran products, sterile technique, and experienced physicians for a safe procedure.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Does Rejuran hurt? Is anesthesia used?<\/div>\n<div class=\"faq-a\">Pain experience: (1) Sensation \u2014 full-face multi-point injection with varying sensitivity by zone: forehead and cheeks are less sensitive; eye and lip areas more so; most describe ‘mild stinging and soreness.’ (2) Anesthesia \u2014 20 minutes of topical cream is standard and greatly reduces discomfort; sensitive patients can discuss stronger anesthesia. (3) Duration \u2014 the actual injection takes 15-20 minutes across dozens to hundreds of points \u2014 a ‘cumulative micro-sting’ rather than one sharp pain. (4) After \u2014 skin feels flushed and warm (like mild sunburn), fading within hours to 1-2 days; a few have mild swelling. (5) Tolerance \u2014 most complete it comfortably under topical anesthesia; pain-sensitive patients may opt for staged sessions or added soothing measures. (6) Rappoel prioritizes comfort \u2014 adequate anesthesia, fine needles, and smooth technique keep the procedure as easy as possible.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How many Rejuran sessions do I need? How often?<\/div>\n<div class=\"faq-a\">Session count explained: (1) Single session \u2014 one session already improves texture (radiance and hydration), but ‘constitutional’ improvements (pores, texture, thickness) require accumulation. (2) Recommended course \u2014 a full course is usually 3 sessions (every 3-4 weeks); by session 3, collagen renewal accumulates into clear, stable skin-quality improvement. (3) Maintenance \u2014 after a full course, a session every 3-6 months maintains results \u2014 skin maintenance is a ‘long-term investment’ like fitness. (4) Timeline \u2014 noticeable at 2-4 weeks after session 1 (glow and hydration); pores, fine lines, and thickness improve clearly after sessions 2-3; results last 6-12 months after the course. (5) By condition \u2014 young or mildly troubled skin may feel clear improvement after 2 sessions; visibly aged or severely damaged skin may need 4-5. (6) Rappoel plans personalized courses \u2014 assessing skin first, then advising the best number and interval of sessions.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How much does Rejuran cost? How is it priced?<\/div>\n<div class=\"faq-a\">Cost explained: (1) Pricing \u2014 Rejuran is priced by ‘formulation plus treatment area’ (e.g., full face, full face plus neck, focused boosting); different versions (standard\/enhanced) have different prices. (2) Price range \u2014 Korea is Rejuran’s home country, so prices are friendlier than elsewhere; Rappoel offers reasonable transparent pricing quoted after consultation. (3) Factors \u2014 formulation, treatment area, whether combined with a skin booster or other treatments, and clinic promotions. (4) Course pricing \u2014 a full 3-session course usually comes with package discounts, more economical than single sessions. (5) Value comparison \u2014 versus spending on high-priced skincare with limited results, Rejuran directly improves skin structure from the dermis \u2014 more efficient as a ‘course mindset’ investment. (6) Rappoel’s principle \u2014 no pushing of unnecessary sessions; planning based on actual skin needs; for detailed pricing, book a free consultation.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Who is suitable for Rejuran? Who is not?<\/div>\n<div class=\"faq-a\">Suitable: (1) those with large pores and rough texture wanting fundamental improvement; (2) those with dry, poorly hydrating skin that absorbs skincare poorly; (3) early-aging skin with fine lines and lost elasticity and radiance; (4) those with redness, sensitivity, and barrier damage (Rejuran’s repair properties suit them especially); (5) those wanting faster repair and lower hyperpigmentation risk after laser or peel treatments; (6) skincare enthusiasts wanting regular ‘skin cultivation’ maintenance. Unsuitable or cautious: (1) pregnancy and breastfeeding (postpone \u2014 insufficient safety data); (2) active infection, severe acne, or skin disease in the area (treat first); (3) severe allergy to fish or DNA components (physician assessment); (4) autoimmune disease or immunosuppressant use (physician assessment); (5) bleeding disorders or anticoagulant use (evaluation needed); (6) severely aged skin expecting ‘one-session transformation’ \u2014 Rejuran accumulates over sessions and requires patience to complete the full course.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long is the recovery after Rejuran? Will it be red or bruised?<\/div>\n<div class=\"faq-a\">Recovery timeline: (1) At injection \u2014 skin flushes and warms (sunburn-like); puncture marks are tiny (mostly ultra-fine needles or cannulas). (2) Day 1 \u2014 the peak of redness and swelling; avoid makeup that day and boost moisturizing repair; a few have small bruises at puncture points. (3) Days 2-3 \u2014 redness clearly subsides; most resume normal makeup and social life (some still slightly flushed). (4) Days 4-7 \u2014 skin returns to normal, and you begin to feel finer texture. (5) Weeks 2-4 \u2014 collagen renewal kicks in; texture improvement (glow, pores) becomes increasingly visible. (6) Bruising \u2014 small red dots at puncture sites are common but tiny, concealable with makeup, fading in 5-7 days; extent depends on constitution and physician technique. (7) Care notes \u2014 avoid exfoliation, acid peels, saunas, strenuous exercise, and sun exposure for 1 week (boost sun protection); avoid irritating skincare. (8) Social planning \u2014 most return to normal social life in 2-3 days; reserve a week before major events.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can Rejuran be combined with other treatments?<\/div>\n<div class=\"faq-a\">Combination strategies: (1) Rejuran plus skin booster \u2014 the classic combo: PN repair and regeneration plus HA deep hydration, solving ‘repair and hydration’ together \u2014 common in Korean dermatology. (2) Rejuran plus pico\/carbon laser \u2014 the laser first handles pigmentation or pores; Rejuran then accelerates skin regeneration during the healing phase, lowering hyperpigmentation and dryness risk \u2014 a complete destroy-then-repair cycle. (3) Rejuran plus botox \u2014 botox relaxes dynamic lines while Rejuran improves static texture \u2014 comprehensive handling of dynamic and static wrinkles. (4) Rejuran plus Thermage\/ultrasound lifting \u2014 devices stimulate deep collagen contraction and remodeling while Rejuran supplies superficial repair nutrients \u2014 deep and superficial anti-aging in combination. (5) Rejuran plus HA filler \u2014 filler addresses local volume deficits while Rejuran improves overall skin quality \u2014 combining points and surface. (6) Sequencing \u2014 most combinations can be done in the same session or 1-2 weeks apart as the physician plans; Rappoel offers personalized ‘skin management programs’ planned in one visit.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">What is the difference between Rejuran and collagen-stimulating fillers like Sculptra?<\/div>\n<div class=\"faq-a\">Ingredient comparison: (1) Rejuran (PN) \u2014 salmon DNA polynucleotide: promotes fibroblast activity and collagen renewal and repairs the barrier; focused on ‘improving skin quality’ with gradual, natural results requiring multiple sessions \u2014 Korea’s national-level maintenance injection. (2) Collagen-stimulating fillers (PLLA\/PCL types) \u2014 poly-L-lactic acid or polycaprolactone microparticles: injected to trigger collagen encapsulation and growth, mainly for ‘filling depressions and volume’ \u2014 used for temples, nasolabial folds, and cheek hollows, with results lasting 1-2+ years. (3) Core difference \u2014 Rejuran is ‘whole-face skin cultivation’ (texture, pores, barrier, fine lines); these fillers are ‘localized volume restoration’ \u2014 different purposes and injection planes. (4) Can they be combined? \u2014 Yes: collagen stimulators fill depressions while Rejuran cultivates the whole face \u2014 but physician planning is needed to avoid overstimulation. (5) Cost differences \u2014 Rejuran requires multiple sessions (lower per-session cost, total depends on count); collagen stimulators cost more per session but last longer. (6) Rappoel recommends the best component combination based on whether your main concern is ‘skin quality’ or ‘volume loss.’<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will one Rejuran session improve my skin? When will I see results?<\/div>\n<div class=\"faq-a\">Result timeline: (1) Immediate after one session \u2014 skin looks dewy thanks to micro-trauma stimulation and the hydrating repair mask (partly temporary). (2) Weeks 1-2 \u2014 the barrier starts repairing; hydration and radiance improve and redness lessens. (3) Weeks 2-4 \u2014 collagen renewal begins; pores and skin feel start improving \u2014 the main perceivable effect of a single session. (4) After session 3 (about 3 months) \u2014 collagen accumulation reaches a tipping point \u2014 pores, fine lines, thickness, and elasticity show clear, stable improvement. (5) Maintenance \u2014 improvements persist for 6-12 months after the full course, gradually returning with natural aging. (6) Honest note \u2014 Rejuran is not a ‘one-shot skin swap’ magic but the science of ‘cumulative cultivation’; clear transformation requires completing the recommended course \u2014 Rappoel plans with a course mindset, not one-off sales. (7) Lifestyle support \u2014 adequate sleep, sun protection, and basic moisturizing amplify Rejuran’s results.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Large pores and fine lines aging your skin?
