Skin boosters and Rejuran are two of Korea's most popular injectable skin treatments for glow, hydration, and texture. Here's what they do, what they cost, and what US patients should know.
Beyond lasers and creams, Korea is known for injectable skin treatments that improve hydration, texture, and glow from within — most famously skin boosters and Rejuran. They're gentle, popular with locals, and priced far below US clinics. (See also our K-beauty dermatology guide and melasma & laser toning guide.)
Skin boosters are micro-injections of hydrating and skin-conditioning ingredients — most often hyaluronic acid (e.g., Juvéderm Volite) — spread across the face. Rather than adding volume like filler, they improve hydration, elasticity, and a natural glow.
Rejuran ("연어주사," the salmon-DNA injection) uses polynucleotides derived from salmon DNA to support skin repair, calm inflammation, and improve fine texture and resilience. It's popular for overall skin quality and delicate areas like under the eyes.
Korean dermatologists administer these injections in extremely high volume, with careful technique and honest expectations. You pay the clinic's own per-session price — with no foreigner markup.
| Treatment | United States | South Korea |
|---|---|---|
| Skin booster (per session) | $400–$700 | $150–$300 |
| Rejuran (per session) | $400–$600 | $150–$350 |
Illustrative ranges in USD; most protocols run a short series of sessions.
Expect tiny injection points and possible mild swelling or small bumps that settle within 1–3 days. There's little to no true downtime, which makes these easy to combine with a short trip. Results build gradually over a series of 2–4 sessions, spaced a few weeks apart.
