The term ‘skin booster’ covers a broad category of injectable skin treatments delivered into the dermis — but the active ingredients and mechanisms vary significantly. Hyaluronic acid skin boosters, Rejuran PDRN boosters, and collagen peptide injections each target different skin concerns and suit different patient profiles. At Rappoel Dermatology in Seoul, we assess each patient’s skin condition before recommending the most appropriate option — or combination.

Frequently Asked Questions
How is a skin booster injection different from applying HA serum?
Topical HA sits on the skin surface and cannot penetrate the dermis. Injectable boosters deliver active ingredients directly into the dermis — hydration efficiency is over 100x greater.
Can Rejuran and HA booster be combined in one session?
Yes. Many patients choose a ‘Rejuran deep repair + HA booster surface hydration’ combination to achieve both structural improvement and immediate luminosity.
What age is appropriate for skin boosters?
From age 20+. Ages 20–30: HA boosters for maintenance hydration. Ages 30+: Add Rejuran for collagen stimulation. Ages 40+: Collagen boosters or comprehensive multi-ingredient combinations.
When can I wash my face after treatment?
Wait 4–6 hours before cleansing. Use a gentle cleanser and avoid rubbing injection sites. Normal skincare resumes the following day.
If I can only visit Seoul once, which booster should I choose?
For longest-lasting benefit (6–12 months), Rejuran is the top recommendation. For a special event within days of treatment, HA booster delivers the fastest visible glow (3–5 days).
