Rejuran types explained: Healer, HB Plus, S, and Eye — which one do you need?

If you've researched skin boosters in Korea, you've probably run into "Rejuran" and assumed it's one treatment. It isn't. Rejuran is actually a small family of injectables, and the type your provider chooses changes what you'll notice in the mirror — and how much the needle will bother you. Here's what each version actually does, and an honest answer to the question everyone asks first: does it hurt?

Rejuran is built on PN (polynucleotide), a regenerative ingredient derived from salmon DNA — which is why it's nicknamed the "salmon injection." Instead of just adding volume like a filler, PN is injected into the dermis to trigger the skin's own repair response: more collagen, calmer inflammation, and gradually firmer, more even-textured skin. The effect builds over a series of sessions rather than appearing overnight.

Rejuran Healer — the all-rounder

The original, baseline formula. Healer targets overall elasticity, fine lines, enlarged pores, and general dermal density. It's the starting point for most patients who want broad "skin quality" improvement rather than a specific fix.

Rejuran HB Plus — the low-pain option

HB Plus takes the Healer base and adds hyaluronic acid plus a lidocaine anesthetic mixed directly into the formula. The hyaluronic acid brings a hydration and glow effect on top of the regenerative one, and the built-in lidocaine cuts discomfort roughly in half compared to standard Healer — which is why it's often marketed as the "low-pain" Rejuran.

Rejuran S — for acne scars

A denser, reformulated version designed for atrophic acne scarring and localized depressed or uneven texture. It's a different tool than Healer: less about overall glow, more about rebuilding structure in scarred areas.

Rejuran I (Eye) — for the under-eye area

A lower-viscosity formula made specifically for the thin, delicate skin around the eyes, aimed at fine lines and the appearance of dark circles and puffiness — areas where the standard formulas would be too dense to use safely.

Rejuran has a real reputation for being one of the more uncomfortable skin boosters, and it's worth explaining why rather than glossing over it. Unlike a filler that glides in smoothly through a cannula, PN is delivered as many individual micro-injections directly into the dermis — that repetition is what patients feel.

That said, discomfort is very manageable in practice:

• Topical numbing cream applied 20–30 minutes before treatment blunts most of the sensation.
• An automated injector device, rather than manual hand injection, delivers each point more consistently and is noticeably less painful.
• HB Plus's built-in lidocaine adds a further layer of comfort for patients who are especially needle-sensitive.

Afterward, small raised bumps (often called "embossing"), mild redness, and occasional light bruising are normal and typically settle within 2–3 days.

Most patients do a series of 3–4 sessions, spaced 2–4 weeks apart. Results are cumulative — each session builds on the last — so a single treatment isn't representative of what Rejuran can actually do.

Many patients actually combine two types in one plan — Healer or HB Plus across the full face, paired with S on scarred zones or I around the eyes.
