Skin Booster — REJURAN Healer (Salmon DNA / PDRN)

REJURAN Healer is a Korean polynucleotide (PDRN) injectable derived from purified salmon DNA. Micro-droplets placed superficially in the dermis trigger fibroblast activity, repair UV-damaged skin, and produce the 'glass skin' look — improved tone, tightened pores, softened fine lines, and stronger barrier function over a 3–4 session course.

REJURAN sits in a category called 'regenerative skin boosters' — it's not a filler (it doesn't add volume) and it's not classic mesotherapy (it doesn't deliver vitamins). Instead, it delivers polynucleotides — short DNA fragments extracted from salmon — that act as a biological signal to the skin's own fibroblasts to upregulate collagen, elastin and hyaluronic acid synthesis, and to repair photoaged tissue. The clinical mechanism is well-published: • Polynucleotide fragments bind to A2A adenosine receptors on fibroblasts • This triggers fibroblast proliferation and migration into damaged tissue • Collagen Type I and III synthesis increases • Inflammatory cytokines decrease — making REJURAN useful for sensitive / rosacea-prone skin where retinoids and lasers can flare At Gen Z Clinic, REJURAN Healer is delivered via 30-gauge needle in a series of micro-droplets (commonly called 'mantoux' technique) across the face — typically 30–50 injection points per session. Each session uses 1–2 vials. The recommended course is 3–4 sessions spaced 4 weeks apart, with maintenance every 6 months. Day-of: small white bumps appear at each injection point and resolve over 2–6 hours. Mild bruising is common at the bony ridges (forehead, jaw). Most clients are presentable the next day. There is no UV restriction beyond ordinary sunscreen. Differentiation vs other skin boosters: • REJURAN repairs damage (radiation, UV, post-laser, post-surgery scars) • Skinvive / Belotero Revive hydrate and improve elasticity • Profhilo (HA hybrid) tightens via bio-remodelling Best results often come from combining REJURAN with one of the others. Gen Z Clinic uses authentic Korean-imported product (PHARMARESEARCH PRODUCTS).
