Rejuran PDRN + Skin Booster Combined Injection in Seoul: Dual Regeneration and Deep Hydration Protocol at Gangnam Station






Rejuran PDRN + Skin Booster Combined Injection in Seoul: Dual Regeneration and Deep Hydration Protocol at Gangnam Station



Skin boosters and Rejuran are two of the most popular injectable skin treatments in Korean dermatology, yet many don’t understand their fundamental difference in purpose: skin boosters deliver 「deep hydration」 by injecting hyaluronic acid and nutrients directly into the dermis for immediate plumping; Rejuran delivers 「PDRN regenerative repair」 — polynucleotides extracted from salmon DNA that promote cellular repair and collagen neogenesis, rebuilding the skin barrier and elasticity. Their synergy is like 「fix the foundation before renovating」 — Rejuran repairs the damaged dermal infrastructure first, while skin boosters provide the moisture and nutritional support. Combined treatment significantly outperforms either alone. Rappoel Dermatology presents the 「PDRN Regeneration + Deep Hydration」 dual-injection protocol, addressing barrier damage, extreme dryness, and dull texture with a complete repair-to-plump solution.

Why Combine Rejuran and Skin Booster — Not Choose One?

  • Rejuran repairs the deep layer, booster hydrates the superficial layer: PDRN stimulates dermal fibroblast proliferation and tissue regeneration; HA absorbs water for immediate volume and plumping — different targets, complementary, not interchangeable
  • Damaged skin 「rejects hydration」: When the skin barrier is compromised, standalone HA hydration is less effective due to rapid transepidermal water loss. PDRN barrier repair first, then hydration, doubles the result
  • PDRN creates a better 「soil」 for lasting hydration: Rejuran promotes microvascular regeneration and tissue repair, improving the dermal microenvironment. Subsequent booster hydration lasts longer in this optimized substrate
  • One appointment, dual benefit: Combined injection can be completed in a single visit, saving travel and time

Ideal Candidates for the Dual-Injection Protocol

  • Compromised skin barrier: Sensitivity, redness, stinging, flaking, 「skin that won’t hold moisture」
  • Severe dehydration: Makeup caking, prominent fine lines, rough and tight skin texture
  • Photoaged skin: Sun-induced loss of elasticity, dullness, enlarged pores
  • Early aging (30+): Accelerated collagen loss, declining luminosity and elasticity with age
  • Post-procedure repair: Skin in recovery after laser or RF treatments — dual injections accelerate healing and prolong results

Rappoel Dual-Injection Protocol

Phase 1: Rejuran PDRN Regenerative Repair (initial treatment, repeatable every 3-4 weeks)

Using Rejuran Healer or Rejuran i, a micro-needle multi-point intradermal injection technique delivers PDRN uniformly across the entire facial dermis. PDRN activates the adenosine A2A receptor pathway upon entering the dermis, stimulating fibroblast proliferation and collagen synthesis while exerting anti-inflammatory repair effects. Procedure duration: 20-30 minutes. Immediate mild erythema resolves in 1-2 days. Regenerative effects become visible progressively, with noticeable improvements in elasticity, smoothness, and firmness at 4 weeks.

Phase 2: Skin Booster Deep Hydration (same session or 1 week apart)

Using an HA + amino acid + vitamin complex booster formulation, delivered via DermaShine/multi-needle injection device at precise superficial-to-mid dermal depth (1.0-1.5mm). Procedure duration: 15-20 minutes, hundreds of micro-injection points. Immediate hydration plumping with visible luminosity and dewiness. Mild erythema resolves in 1-3 days.

Optimal Treatment Rhythm (two options)

Option A: Fast-Track (Same-Session Combined)

Rejuran PDRN injection first (deep dermal regeneration), followed by skin booster (superficial hydration and sealing) in the same appointment. Ideal for short-stay visitors to Seoul. Recovery: 2-4 days of mild erythema; results visible within 1 week.

Option B: Layered Accumulation (1-2 weeks apart)

Session 1: Rejuran PDRN, allowing 1-2 weeks for initial tissue repair activation. Session 2: Skin booster delivers hydration into the optimized dermal substrate. Ideal for those with adequate recovery time seeking maximum cumulative results. Recovery: 2-3 days per session, with progressive improvement visible between sessions.

Rappoel Dermatology recommends Option A for first-time clients and Option B for maintenance. The initial Rejuran course consists of 3 sessions (at 3-4 week intervals), with skin boosters administered at each or every other Rejuran session. All products are authentic and administered by experienced physicians. Located 3 minutes from Gangnam Station Exit 10, with Chinese and English consultation available.

Frequently Asked Questions

Can Rejuran and skin booster be done on the same day?
Yes — and Rappoel recommends same-session combination (Option A). Injection sequence: Rejuran first (deep dermal PDRN regeneration at 1.5-2.0mm depth), then skin booster (superficial-to-mid dermal hydration at 1.0-1.5mm depth). The two depths do not interfere. The advantage is a single swelling and recovery window, though it requires adequate skin tolerance. The physician will assess suitability for same-session combination.
How much better is Rejuran + skin booster vs. skin booster alone?
Skin booster alone: immediate plumping is noticeable, but hydration typically lasts only 2-4 weeks as the skin’s underlying structure and barrier haven’t improved. Rejuran + skin booster: PDRN repairs the dermal architecture first, creating a better microenvironment — hydration is not only immediately visible but lasts 4-8 weeks. The analogy: standalone booster is like 「pouring water into a leaky bucket」; Rejuran + booster is like 「patching the bucket first, then filling it.」 Combined results typically outperform standalone treatment by 30-50% across radiance, elasticity, and smoothness.
How red will my skin be after dual injection? When can I use makeup?
Rejuran produces a uniform papular micro-erythema pattern (hundreds of tiny injection points); skin booster produces diffuse redness. Combined post-treatment erythema is moderate, resolving in 2-4 days. Rappoel guidance: (1) no water contact or makeup for 24 hours; (2) gentle lukewarm water cleansing from day 2; (3) light makeup from day 3 (sheer serum + mineral powder); (4) avoid heavy makeup and vigorous cleansing for 1 week. For important social events, allow 3-5 days recovery.
How many sessions for noticeable results?
Rejuran PDRN regeneration is cumulative: Session 1 → subtle skin elasticity improvement and fine line softening at ~4 weeks; Session 2 (at 4-week interval) → significant improvement in luminosity and smoothness; Session 3 (at 4-week interval) → regenerative peak of the initial course. Recommended protocol: 3 Rejuran + 2-3 booster sessions within 3-4 months, then maintenance every 3-6 months (1 Rejuran + 1 booster). Effects compound with each session; consistent investment yields the most lasting results.
What’s the difference between Rejuran and skin booster brands?
Rejuran by PharmaResearch (Korea): core ingredient PDRN (polynucleotides) extracted from salmon DNA. Product lines include Rejuran Healer (full-face regeneration), Rejuran i (periocular), Rejuran S (scar repair), Rejuran HB (enhanced full-face). Skin booster brands include DermaShine, Aquashine, Bellacel, and others with various compound formulations. Rappoel uses authentic Korean Rejuran and selects the most suitable booster formulation based on individual skin type and needs.
