How Long Does PRP Last? Complete Course Guide | Rappoel Dermatology Seoul<\/h1>\n<div class=\"sub\">The standard PRP course is 3-4 sessions spaced 4-6 weeks apart, with results lasting 12-18 months. As an autologous treatment it carries zero rejection risk, but the result still varies by age and individual biology \u2014 younger patients with good baseline may need only 3 sessions; significant aging may require 4+ sessions with other treatments.<\/div>\n<\/p><\/div>\n<div class=\"highlight\">\n<p><strong>Direct answer:<\/strong> The standard PRP course is 3-4 sessions spaced 4-6 weeks apart; results last 12-18 months. The actual number of sessions depends on age and skin condition: patients aged 30-40 with mild aging usually follow 3 sessions; those aged 40-50 with noticeable aging often need 4; patients 50+ with significant aging may require 4+ sessions combined with other treatments. PRP uses the patient’s own blood, so zero rejection is the headline advantage, but results still vary by biology.<\/p>\n<\/div>\n<p>‘How many PRP sessions do I need? How is it different from skin booster?’ are the two most common PRP questions at Rappoel Dermatology near Gangnam Station. PRP uses the patient’s own blood-derived high-concentration platelet plasma and is considered one of the most ‘natural’ non-filler injection treatments. This article consolidates the real clinical session count, timeline, side effects, and best-fit patient profile.<\/p>\n<h2>What is PRP? How it differs from skin booster and Rejuran<\/h2>\n<p>PRP (Platelet-Rich Plasma) is a treatment that draws the patient’s own blood, centrifuges it to obtain growth-factor-rich plasma, and reinjects it into the skin. Platelet growth factors stimulate collagen production, skin repair, and angiogenesis. How PRP differs from other skin injection treatments:<\/p>\n<ul>\n<li><strong>Skin booster (HA + nutrients):<\/strong> external ingredients \u2014 relies on HA hydration and nutrients, immediate effect but short maintenance (1-3 months)<\/li>\n<li><strong>Rejuran (PDRN, salmon DNA):<\/strong> external repair ingredient \u2014 relies on PDRN stimulating cell regeneration, gradual effect lasting about 6-12 months<\/li>\n<li><strong>PRP (autologous serum):<\/strong> autologous growth factors \u2014 uses the patient’s own blood-derived growth factors to stimulate collagen; gradual effect, lasting 12-18 months; zero rejection is the headline advantage<\/li>\n<\/ul>\n<p>Simple memory: skin booster ‘hydrates immediately’; Rejuran ‘uses external repair’; PRP ‘uses your own blood to stimulate your own repair.’<\/p>\n<h2>How many PRP sessions? Three categories by age and skin condition<\/h2>\n<p>The number of PRP sessions is mainly determined by ‘age’ and ‘skin condition.’ Rappoel’s clinical session recommendation:<\/p>\n<ul>\n<li><strong>Ages 30-40, good skin (mild pores, fine lines):<\/strong> standard 3-session course is enough \u2014 skin still has natural repair ability, small stimulation brings clear improvement<\/li>\n<li><strong>Ages 40-50, declining skin (large pores, noticeable fine lines):<\/strong> 3-4 sessions recommended \u2014 skin repair ability has declined, more stimulation is needed for stable improvement<\/li>\n<li><strong>Age 50+, significant aging (deep wrinkles, dull tone):<\/strong> usually 4+ sessions \u2014 may combine with skin booster, Rejuran, Thermage FLX, etc.<\/li>\n<li><strong>Adjunctive use (combined with other treatments):<\/strong> single PRP combined with laser, Ultherapy, Thermage \u2014 accelerates repair and boosts overall effect<\/li>\n<\/ul>\n<p>Key concept: PRP is a ‘gradual self-repair stimulation’ treatment \u2014 results need time to accumulate and vary by individual biology, similar to Sculptra but with higher safety due to fully autologous source.<\/p>\n<h2>When will PRP results appear? Complete timeline<\/h2>\n<p>Unlike most fillers, PRP is a ‘gradual’ treatment and needs time to accumulate. The complete effect timeline:<\/p>\n<ul>\n<li><strong>Immediately after:<\/strong> mild redness and swelling at injection sites; the injection volume makes skin slightly full \u2014 this is not the final result, fading in 1-2 days<\/li>\n<li><strong>1-2 weeks:<\/strong> redness fully resolves, skin feels more stable than before<\/li>\n<li><strong>4-6 weeks (at session 2):<\/strong> growth factors from session 1 enter active phase; skin feels thicker and brighter; physician assesses whether to adjust session 2 dose<\/li>\n<li><strong>3 months:<\/strong> collagen regeneration and skin repair become visible; pores, fine lines, and tone improve<\/li>\n<li><strong>6 months:<\/strong> full effect \u2014 this is PRP’s real appearance<\/li>\n<li><strong>12-18 months:<\/strong> effect gradually fades; consider the next full course<\/li>\n<\/ul>\n<h2>PRP’s limitations and who should not get it<\/h2>\n<p>Although PRP has ‘zero rejection,’ it is not for everyone, and results are not universally satisfying:<\/p>\n<ul>\n<li><strong>Results vary greatly by biology:<\/strong> platelet concentration and growth factor activity vary with the patient’s health status and age \u2014 chronic lack of sleep, smoking, or malnutrition may reduce effectiveness<\/li>\n<li><strong>Who should not get PRP:<\/strong> pregnant or breastfeeding patients, blood disorders (e.g., thrombocytopenia, hemophilia), patients on anticoagulants, those with infection or inflammation at injection sites, autoimmune disease patients<\/li>\n<li><strong>Limited-effect patients:<\/strong> 60+ with significant aging \u2014 PRP alone has limited effect, needs to combine with other treatments; patients with unrealistic expectations \u2014 PRP is not ‘instant fullness’<\/li>\n<li><strong>Treatments PRP cannot replace:<\/strong> PRP cannot replace Botox for deep wrinkles, ultrasound lifting for obvious laxity, HA filler for obvious volume loss \u2014 it is ‘adjunctive rejuvenation,’ not ‘comprehensive rejuvenation’<\/li>\n<\/ul>\n<h2>How to choose between PRP and Rejuran?<\/h2>\n<p>PRP and Rejuran both belong to ‘gradual skin rejuvenation’ treatments, but their source and mechanism differ:<\/p>\n<ul>\n<li><strong>PRP (autologous serum):<\/strong> source is the patient’s own blood, growth factors are diverse \u2014 advantage is ‘zero rejection’; lasting 12-18 months; suits patients pursuing ‘natural, no foreign substances’<\/li>\n<li><strong>Rejuran (PDRN, salmon DNA):<\/strong> source is external PDRN, structure is stable \u2014 advantage is ‘predictable effect, stable quality’; lasting about 6-12 months; suits patients pursuing ‘stable quality, predictable effect’<\/li>\n<li><strong>Cost and sessions:<\/strong> PRP requires blood draw and centrifugation, so the per-session cost is higher; Rejuran is relatively cheaper per session<\/li>\n<li><strong>Best fit:<\/strong> PRP is more effective for dull tone and large pores; Rejuran is more effective for fine lines and sensitive skin repair. The choice should be made with a physician based on individual skin and expectations<\/li>\n<\/ul>\n<p>Many patients alternate PRP and Rejuran to combine the ‘autologous’ and ‘external stable’ advantages, but this requires physician planning.<\/p>\n<h2>What a real PRP session looks like at Rappoel<\/h2>\n<p>Beyond individual biology, PRP’s effect largely depends on centrifugation purification and injection depth. Rappoel’s standard procedure:<\/p>\n<ul>\n<li><strong>Step 1 \u00b7 Consultation and blood check:<\/strong> physician learns the patient’s skin condition and expectations; if the patient has blood disorders or is on anticoagulants, the physician evaluates suitability<\/li>\n<li><strong>Step 2 \u00b7 Blood draw:<\/strong> about 10-20ml of venous blood is drawn into a special tube<\/li>\n<li><strong>Step 3 \u00b7 Centrifugation:<\/strong> use a certified PRP kit and centrifuge to separate high-concentration platelet plasma \u2014 centrifugation speed and time directly affect PRP purity<\/li>\n<li><strong>Step 4 \u00b7 Photo documentation:<\/strong> frontal and lateral before-photos as baseline for the course<\/li>\n<li><strong>Step 5 \u00b7 Numbing:<\/strong> topical anesthetic for about 20-30 minutes<\/li>\n<li><strong>Step 6 \u00b7 Layered injection:<\/strong> physician injects in layered fashion into subcutaneous or dermal depths using a skin booster gun or cannula<\/li>\n<li><strong>Step 7 \u00b7 Post-care:<\/strong> explains post-treatment precautions and schedules the next session (4-6 weeks later)<\/li>\n<\/ul>\n<p>Rappoel uses certified PRP kits and centrifuges; the purity and concentration of each batch are strictly controlled \u2014 this is the key to stable PRP effect.<\/p>\n<h2>Post-PRP precautions and common side effects<\/h2>\n<p>Because PRP is autologous, side effects are minimal, but post-care is still important:<\/p>\n<ul>\n<li><strong>Common and temporary side effects:<\/strong> mild redness, swelling, and bruising at injection sites (1-2 weeks); short-term tenderness at injection sites<\/li>\n<li><strong>Rare but worth noting:<\/strong> local infection (very rare, related to aseptic technique), allergic reaction (very rare even with autologous serum, but still worth noting)<\/li>\n<li><strong>Day of treatment:<\/strong> normal work is fine but avoid strenuous exercise and high-heat environments<\/li>\n<li><strong>First week:<\/strong> avoid saunas, steam rooms, hot yoga; do not press hard on injection areas; intensify moisturizing and sun protection<\/li>\n<li><strong>Interval to next session:<\/strong> at least 4 weeks; most patients follow 4-6 weeks to complete the course<\/li>\n<\/ul>\n<p><strong>Related reading:<\/strong> the comprehensive PRP introduction is at <a href=\"https:\/\/rappoel-clinic.com\/prp-skin-rejuvenation-en\/\">PRP skin rejuvenation in Seoul<\/a>; Rejuran skin booster course frequency is at <a href=\"https:\/\/rappoel-clinic.com\/rejuran-pdrn-skin-regeneration-en\/\">Rejuran PDRN skin regeneration in Seoul<\/a>; the full PRP vs Rejuran comparison is at <a href=\"https:\/\/rappoel-clinic.com\/rejuran-pn-skin-booster-repair-en\/\">Rejuran skin booster in Seoul<\/a>.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How many PRP sessions do you need?<\/div>\n<div class=\"faq-a\">The standard course is 3-4 sessions spaced 4-6 weeks apart. Patients aged 30-40 with mild aging usually follow 3 sessions; those aged 40-50 with noticeable aging often need 4; patients 50+ with significant aging may require 4+ sessions combined with other treatments. PRP is a ‘gradual self-repair stimulation’ treatment \u2014 full results usually appear 3-6 months after the course ends, which is fundamentally different from skin booster (immediate effect).<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long does PRP last?<\/div>\n<div class=\"faq-a\">Average 12-18 months. The effect reaches completion 3-6 months after the course ends and then gradually fades as the skin naturally turns over. Duration depends on age, skin condition, and lifestyle \u2014 younger patients with good maintenance can reach close to 18 months; older patients with irregular lifestyle may see around 12 months.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How soon will PRP results appear?<\/div>\n<div class=\"faq-a\">1-2 weeks after treatment redness resolves and skin feels more stable; 4-6 weeks (at session 2) skin feels thicker and brighter; 3 months pores, fine lines, and tone show clear improvement; 6 months the effect reaches completion. ‘Immediate fullness after injection’ is not PRP’s characteristic \u2014 it is a gradual treatment that accumulates over time.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is PRP safe? Will there be rejection?<\/div>\n<div class=\"faq-a\">Because PRP uses the patient’s own blood-derived plasma, zero rejection is the headline advantage. Common side effects are only mild redness, swelling, and bruising (1-2 weeks); serious side effects are extremely rare. But PRP is not for everyone \u2014 blood disorders (e.g., thrombocytopenia, hemophilia), anticoagulants, and autoimmune disease patients should avoid PRP.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How do I choose between PRP and Rejuran?<\/div>\n<div class=\"faq-a\">PRP (autologous serum) has the advantage of ‘zero rejection and natural source,’ lasting 12-18 months, more effective for dull tone and large pores. Rejuran (PDRN) has the advantage of ‘predictable effect and stable quality,’ lasting about 6-12 months, more effective for fine lines and sensitive skin repair. Many patients alternate PRP and Rejuran to combine both advantages, but this requires physician planning.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Who should not get PRP?<\/div>\n<div class=\"faq-a\">Pregnant or breastfeeding patients, those with blood disorders (e.g., thrombocytopenia, hemophilia), patients on anticoagulants, those with infection or inflammation at injection sites, and patients with autoimmune diseases should avoid PRP. PRP effect may be reduced in patients with chronic lack of sleep, smoking, or malnutrition \u2014 platelet concentration and growth factor activity are affected by health status.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">What if PRP ‘fails’ or the effect is not obvious?<\/div>\n<div class=\"faq-a\">Four common reasons: course not completed (standard is 3-4 sessions; 1-2 sessions alone has limited effect); time not reached (full effect needs 6 months); individual biology (platelet activity, health status); insufficient clinic centrifugation technique (PRP purity directly affects effect). Choosing a certified PRP kit and an experienced physician is the key to ensuring effect.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can PRP be combined with other treatments?<\/div>\n<div class=\"faq-a\">Yes, and common combinations actually enhance the overall effect: Botox (1-week interval), skin booster (2-4 weeks apart), Rejuran (often alternated, 2-4 weeks apart), Thermage FLX\/Ultherapy (1-3 months apart), Pico laser (PRP accelerates repair; usually given 1-2 weeks after laser).<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How is PRP different from skin booster?<\/div>\n<div class=\"faq-a\">PRP is ‘autologous growth factor injection’ \u2014 uses the patient’s own blood-derived platelet growth factors, zero rejection, gradual effect, lasting 12-18 months. Skin booster is ‘HA + nutrient injection’ \u2014 external ingredients, mainly relying on HA hydration and nutrients, immediate effect but short maintenance (1-3 months). Their mechanisms differ and they are often combined \u2014 skin booster hydrates, PRP repairs.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long until normal life after PRP?<\/div>\n<div class=\"faq-a\">Normal work is fine the same day but avoid strenuous exercise and high-heat environments. The first week avoid saunas, steam rooms, hot yoga; do not press hard on injection areas; intensify moisturizing and sun protection. Most redness and bruising fade within 1-2 weeks.

As an autologous treatment it carries zero rejection risk, but the result still varies by age and individual biology \u2014 younger patients with good baseline may need only 3 sessions; significant aging may require 4+ sessions with other treatments.<\/div>\n<\/p><\/div>\n<div class=\"highlight\">\n<p><strong>Direct answer:<\/strong> The standard PRP course is 3-4 sessions spaced 4-6 weeks apart; results last 12-18 months. The actual number of sessions depends on age and skin condition: patients aged 30-40 with mild aging usually follow 3 sessions; those aged 40-50 with noticeable aging often need 4; patients 50+ with significant aging may require 4+ sessions combined with other treatments. PRP uses the patient’s own blood, so zero rejection is the headline advantage, but results still vary by biology.<\/p>\n<\/div>\n<p>‘How many PRP sessions do I need? How is it different from skin booster?’ are the two most common PRP questions at Rappoel Dermatology near Gangnam Station. PRP uses the patient’s own blood-derived high-concentration platelet plasma and is considered one of the most ‘natural’ non-filler injection treatments. This article consolidates the real clinical session count, timeline, side effects, and best-fit patient profile.<\/p>\n<h2>What is PRP? How it differs from skin booster and Rejuran<\/h2>\n<p>PRP (Platelet-Rich Plasma) is a treatment that draws the patient’s own blood, centrifuges it to obtain growth-factor-rich plasma, and reinjects it into the skin. Platelet growth factors stimulate collagen production, skin repair, and angiogenesis. How PRP differs from other skin injection treatments:<\/p>\n<ul>\n<li><strong>Skin booster (HA + nutrients):<\/strong> external ingredients \u2014 relies on HA hydration and nutrients, immediate effect but short maintenance (1-3 months)<\/li>\n<li><strong>Rejuran (PDRN, salmon DNA):<\/strong> external repair ingredient \u2014 relies on PDRN stimulating cell regeneration, gradual effect lasting about 6-12 months<\/li>\n<li><strong>PRP (autologous serum):<\/strong> autologous growth factors \u2014 uses the patient’s own blood-derived growth factors to stimulate collagen; gradual effect, lasting 12-18 months; zero rejection is the headline advantage<\/li>\n<\/ul>\n<p>Simple memory: skin booster ‘hydrates immediately’; Rejuran ‘uses external repair’; PRP ‘uses your own blood to stimulate your own repair.’<\/p>\n<h2>How many PRP sessions? Three categories by age and skin condition<\/h2>\n<p>The number of PRP sessions is mainly determined by ‘age’ and ‘skin condition.’ Rappoel’s clinical session recommendation:<\/p>\n<ul>\n<li><strong>Ages 30-40, good skin (mild pores, fine lines):<\/strong> standard 3-session course is enough \u2014 skin still has natural repair ability, small stimulation brings clear improvement<\/li>\n<li><strong>Ages 40-50, declining skin (large pores, noticeable fine lines):<\/strong> 3-4 sessions recommended \u2014 skin repair ability has declined, more stimulation is needed for stable improvement<\/li>\n<li><strong>Age 50+, significant aging (deep wrinkles, dull tone):<\/strong> usually 4+ sessions \u2014 may combine with skin booster, Rejuran, Thermage FLX, etc.<\/li>\n<li><strong>Adjunctive use (combined with other treatments):<\/strong> single PRP combined with laser, Ultherapy, Thermage \u2014 accelerates repair and boosts overall effect<\/li>\n<\/ul>\n<p>Key concept: PRP is a ‘gradual self-repair stimulation’ treatment \u2014 results need time to accumulate and vary by individual biology, similar to Sculptra but with higher safety due to fully autologous source.<\/p>\n<h2>When will PRP results appear? Complete timeline<\/h2>\n<p>Unlike most fillers, PRP is a ‘gradual’ treatment and needs time to accumulate. The complete effect timeline:<\/p>\n<ul>\n<li><strong>Immediately after:<\/strong> mild redness and swelling at injection sites; the injection volume makes skin slightly full \u2014 this is not the final result, fading in 1-2 days<\/li>\n<li><strong>1-2 weeks:<\/strong> redness fully resolves, skin feels more stable than before<\/li>\n<li><strong>4-6 weeks (at session 2):<\/strong> growth factors from session 1 enter active phase; skin feels thicker and brighter; physician assesses whether to adjust session 2 dose<\/li>\n<li><strong>3 months:<\/strong> collagen regeneration and skin repair become visible; pores, fine lines, and tone improve<\/li>\n<li><strong>6 months:<\/strong> full effect \u2014 this is PRP’s real appearance<\/li>\n<li><strong>12-18 months:<\/strong> effect gradually fades; consider the next full course<\/li>\n<\/ul>\n<h2>PRP’s limitations and who should not get it<\/h2>\n<p>Although PRP has ‘zero rejection,’ it is not for everyone, and results are not universally satisfying:<\/p>\n<ul>\n<li><strong>Results vary greatly by biology:<\/strong> platelet concentration and growth factor activity vary with the patient’s health status and age \u2014 chronic lack of sleep, smoking, or malnutrition may reduce effectiveness<\/li>\n<li><strong>Who should not get PRP:<\/strong> pregnant or breastfeeding patients, blood disorders (e.g., thrombocytopenia, hemophilia), patients on anticoagulants, those with infection or inflammation at injection sites, autoimmune disease patients<\/li>\n<li><strong>Limited-effect patients:<\/strong> 60+ with significant aging \u2014 PRP alone has limited effect, needs to combine with other treatments; patients with unrealistic expectations \u2014 PRP is not ‘instant fullness’<\/li>\n<li><strong>Treatments PRP cannot replace:<\/strong> PRP cannot replace Botox for deep wrinkles, ultrasound lifting for obvious laxity, HA filler for obvious volume loss \u2014 it is ‘adjunctive rejuvenation,’ not ‘comprehensive rejuvenation’<\/li>\n<\/ul>\n<h2>How to choose between PRP and Rejuran?<\/h2>\n<p>PRP and Rejuran both belong to ‘gradual skin rejuvenation’ treatments, but their source and mechanism differ:<\/p>\n<ul>\n<li><strong>PRP (autologous serum):<\/strong> source is the patient’s own blood, growth factors are diverse \u2014 advantage is ‘zero rejection’; lasting 12-18 months; suits patients pursuing ‘natural, no foreign substances’<\/li>\n<li><strong>Rejuran (PDRN, salmon DNA):<\/strong> source is external PDRN, structure is stable \u2014 advantage is ‘predictable effect, stable quality’; lasting about 6-12 months; suits patients pursuing ‘stable quality, predictable effect’<\/li>\n<li><strong>Cost and sessions:<\/strong> PRP requires blood draw and centrifugation, so the per-session cost is higher; Rejuran is relatively cheaper per session<\/li>\n<li><strong>Best fit:<\/strong> PRP is more effective for dull tone and large pores; Rejuran is more effective for fine lines and sensitive skin repair. The choice should be made with a physician based on individual skin and expectations<\/li>\n<\/ul>\n<p>Many patients alternate PRP and Rejuran to combine the ‘autologous’ and ‘external stable’ advantages, but this requires physician planning.<\/p>\n<h2>What a real PRP session looks like at Rappoel<\/h2>\n<p>Beyond individual biology, PRP’s effect largely depends on centrifugation purification and injection depth. Rappoel’s standard procedure:<\/p>\n<ul>\n<li><strong>Step 1 \u00b7 Consultation and blood check:<\/strong> physician learns the patient’s skin condition and expectations; if the patient has blood disorders or is on anticoagulants, the physician evaluates suitability<\/li>\n<li><strong>Step 2 \u00b7 Blood draw:<\/strong> about 10-20ml of venous blood is drawn into a special tube<\/li>\n<li><strong>Step 3 \u00b7 Centrifugation:<\/strong> use a certified PRP kit and centrifuge to separate high-concentration platelet plasma \u2014 centrifugation speed and time directly affect PRP purity<\/li>\n<li><strong>Step 4 \u00b7 Photo documentation:<\/strong> frontal and lateral before-photos as baseline for the course<\/li>\n<li><strong>Step 5 \u00b7 Numbing:<\/strong> topical anesthetic for about 20-30 minutes<\/li>\n<li><strong>Step 6 \u00b7 Layered injection:<\/strong> physician injects in layered fashion into subcutaneous or dermal depths using a skin booster gun or cannula<\/li>\n<li><strong>Step 7 \u00b7 Post-care:<\/strong> explains post-treatment precautions and schedules the next session (4-6 weeks later)<\/li>\n<\/ul>\n<p>Rappoel uses certified PRP kits and centrifuges; the purity and concentration of each batch are strictly controlled \u2014 this is the key to stable PRP effect.<\/p>\n<h2>Post-PRP precautions and common side effects<\/h2>\n<p>Because PRP is autologous, side effects are minimal, but post-care is still important:<\/p>\n<ul>\n<li><strong>Common and temporary side effects:<\/strong> mild redness, swelling, and bruising at injection sites (1-2 weeks); short-term tenderness at injection sites<\/li>\n<li><strong>Rare but worth noting:<\/strong> local infection (very rare, related to aseptic technique), allergic reaction (very rare even with autologous serum, but still worth noting)<\/li>\n<li><strong>Day of treatment:<\/strong> normal work is fine but avoid strenuous exercise and high-heat environments<\/li>\n<li><strong>First week:<\/strong> avoid saunas, steam rooms, hot yoga; do not press hard on injection areas; intensify moisturizing and sun protection<\/li>\n<li><strong>Interval to next session:<\/strong> at least 4 weeks; most patients follow 4-6 weeks to complete the course<\/li>\n<\/ul>\n<p><strong>Related reading:<\/strong> the comprehensive PRP introduction is at <a href=\"https:\/\/rappoel-clinic.com\/prp-skin-rejuvenation-en\/\">PRP skin rejuvenation in Seoul<\/a>; Rejuran skin booster course frequency is at <a href=\"https:\/\/rappoel-clinic.com\/rejuran-pdrn-skin-regeneration-en\/\">Rejuran PDRN skin regeneration in Seoul<\/a>; the full PRP vs Rejuran comparison is at <a href=\"https:\/\/rappoel-clinic.com\/rejuran-pn-skin-booster-repair-en\/\">Rejuran skin booster in Seoul<\/a>.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How many PRP sessions do you need?<\/div>\n<div class=\"faq-a\">The standard course is 3-4 sessions spaced 4-6 weeks apart. Patients aged 30-40 with mild aging usually follow 3 sessions; those aged 40-50 with noticeable aging often need 4; patients 50+ with significant aging may require 4+ sessions combined with other treatments. PRP is a ‘gradual self-repair stimulation’ treatment \u2014 full results usually appear 3-6 months after the course ends, which is fundamentally different from skin booster (immediate effect).<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long does PRP last?<\/div>\n<div class=\"faq-a\">Average 12-18 months. The effect reaches completion 3-6 months after the course ends and then gradually fades as the skin naturally turns over. Duration depends on age, skin condition, and lifestyle \u2014 younger patients with good maintenance can reach close to 18 months; older patients with irregular lifestyle may see around 12 months.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How soon will PRP results appear?<\/div>\n<div class=\"faq-a\">1-2 weeks after treatment redness resolves and skin feels more stable; 4-6 weeks (at session 2) skin feels thicker and brighter; 3 months pores, fine lines, and tone show clear improvement; 6 months the effect reaches completion. ‘Immediate fullness after injection’ is not PRP’s characteristic \u2014 it is a gradual treatment that accumulates over time.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is PRP safe? Will there be rejection?<\/div>\n<div class=\"faq-a\">Because PRP uses the patient’s own blood-derived plasma, zero rejection is the headline advantage. Common side effects are only mild redness, swelling, and bruising (1-2 weeks); serious side effects are extremely rare. But PRP is not for everyone \u2014 blood disorders (e.g., thrombocytopenia, hemophilia), anticoagulants, and autoimmune disease patients should avoid PRP.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How do I choose between PRP and Rejuran?<\/div>\n<div class=\"faq-a\">PRP (autologous serum) has the advantage of ‘zero rejection and natural source,’ lasting 12-18 months, more effective for dull tone and large pores. Rejuran (PDRN) has the advantage of ‘predictable effect and stable quality,’ lasting about 6-12 months, more effective for fine lines and sensitive skin repair. Many patients alternate PRP and Rejuran to combine both advantages, but this requires physician planning.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Who should not get PRP?<\/div>\n<div class=\"faq-a\">Pregnant or breastfeeding patients, those with blood disorders (e.g., thrombocytopenia, hemophilia), patients on anticoagulants, those with infection or inflammation at injection sites, and patients with autoimmune diseases should avoid PRP. PRP effect may be reduced in patients with chronic lack of sleep, smoking, or malnutrition \u2014 platelet concentration and growth factor activity are affected by health status.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">What if PRP ‘fails’ or the effect is not obvious?<\/div>\n<div class=\"faq-a\">Four common reasons: course not completed (standard is 3-4 sessions; 1-2 sessions alone has limited effect); time not reached (full effect needs 6 months); individual biology (platelet activity, health status); insufficient clinic centrifugation technique (PRP purity directly affects effect). Choosing a certified PRP kit and an experienced physician is the key to ensuring effect.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can PRP be combined with other treatments?<\/div>\n<div class=\"faq-a\">Yes, and common combinations actually enhance the overall effect: Botox (1-week interval), skin booster (2-4 weeks apart), Rejuran (often alternated, 2-4 weeks apart), Thermage FLX\/Ultherapy (1-3 months apart), Pico laser (PRP accelerates repair; usually given 1-2 weeks after laser).<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How is PRP different from skin booster?<\/div>\n<div class=\"faq-a\">PRP is ‘autologous growth factor injection’ \u2014 uses the patient’s own blood-derived platelet growth factors, zero rejection, gradual effect, lasting 12-18 months. Skin booster is ‘HA + nutrient injection’ \u2014 external ingredients, mainly relying on HA hydration and nutrients, immediate effect but short maintenance (1-3 months). Their mechanisms differ and they are often combined \u2014 skin booster hydrates, PRP repairs.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long until normal life after PRP?<\/div>\n<div class=\"faq-a\">Normal work is fine the same day but avoid strenuous exercise and high-heat environments. The first week avoid saunas, steam rooms, hot yoga; do not press hard on injection areas; intensify moisturizing and sun protection. Most redness and bruising fade within 1-2 weeks. The interval to the next session is at least 4 weeks; most patients follow 4-6 weeks to complete the standard course.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Wondering if PRP fits your skin?
