Skin booster (스킨부스터).

Microdroplet injections of a non-volumizing product into the dermis, aimed at improving hydration, elasticity, fine line density, and overall skin quality. Unlike fillers, the point is not to change shape — it's to change tissue behavior.

Rejuran (리쥬란, polynucleotide from salmon DNA) is the flagship Korean product — originally developed for scar healing, now a mass-market skin treatment. Profhilo (hybrid HA) is the Italian gold standard for hydration. Juvelook (PLLA microspheres) stimulates collagen. SkinVive (Juvederm's micro-HA product) is newer. Most clinics offer 2–3 of these.

Typically 3–5 sessions spaced 2–4 weeks apart, followed by maintenance every 4–6 months. Often combined with laser toning or low-fluence picolaser in the same visit.

Small bumps at each injection point for 12–24 hours — longer with some products. Occasional minor bruising. Makeup can usually be applied the next day.

Rejuran: ₩250,000–₩400,000 per session. Profhilo: ₩350,000–₩600,000 per session. Juvelook: ₩300,000–₩500,000 per session. Packages of 3–5 sessions are typically priced 10–20% below single-session totals.

"Which product do you recommend for my specific concern, and why not the others?" A good skin-booster consultation should result in product-level specificity, not a generic menu.
