Rejuran Healer (PDRN Injection)

Rejuran contains Polydeoxyribonucleotide (PDRN), derived from salmon DNA that is structurally similar to human DNA. When injected intradermally, PDRN acts as a cell growth stimulator — it binds to adenosine receptors which activates wound healing pathways, stimulates fibroblast activity, and increases production of collagen, elastin, and hyaluronic acid. It essentially "wakes up" dormant skin repair mechanisms. The results compound with multiple sessions.

Treatment takes 30–45 minutes. Topical numbing cream is applied 30–45 minutes beforehand. The injections are made via a micro-needling technique (multiple micro-injections) or a mesotherapy gun across the entire face. You will experience mild to moderate pain (4–6/10) during the procedure. Immediately after: significant swelling and papules at injection sites (looks alarming — completely normal). These resolve within 24–48 hours. Avoid makeup, exercise, and saunas for 24 hours.

Rejuran (리쥬란) was developed by Pharmaresearch Korea and launched in South Korea around 2014. It quickly became one of the most sought-after treatments in Korean dermatology clinics, earning the nickname "아기피부 (baby skin) injection" due to its skin texture-improving effects. The treatment is now available globally but remains most affordable and prevalent in Korea (₩100,000–300,000 per session). Clinical studies from Korean universities show significant improvement in skin elasticity and hydration biomarkers.
