The 6 Peptide Skin Booster Serum

Why is your skin still sagging, dull, and losing its bounce, even with a full skincare routine?

Here's the uncomfortable truth: most serums tackle one problem at a time. One product for fine lines. Another for dullness. Another for pores. Another for hydration. By the time you've layered four products, you've spent a fortune, overloaded your skin, and you're still not addressing the real issue, your skin's scaffolding is weakening. Collagen signals are slowing. Skin cell communication is breaking down.

Description:

This is the serum for people who are done compromising. Whether your skin is showing early signs of ageing, struggling with persistent dullness, battling uneven texture, or losing the firmness it once had, the COSRX 6 Peptide Skin Booster was built for exactly that kind of complexity.

Six distinct peptides, each chosen for a different function, firming, brightening, pore refinement, sebum control, soothing, and deep repair, work in concert within a featherlight, toner-weight formula. It absorbs in seconds, leaves zero residue, and starts communicating with your skin immediately.

Clinically tested for sensitive skin, acne-prone skin, and hypoallergenic tolerability, this isn't just a luxury product; it's a precision tool. And at 150ml, it's a full course of treatment, not a trial-sized promise.

Six targeted peptides. One seamless formula.

Instead of buying separate solutions for wrinkles, dullness, pores, sagging, uneven tone, and sensitivity, this single booster addresses all of them in one effortless step.

Visible lifting and firming, not just surface hydration.

The peptide complex reaches beneath the surface to support your skin's structural proteins the difference between skin that looks plumped and skin that is genuinely stronger.

Instant absorption, zero heaviness.

The toner-weight texture means no greasiness, no pilling, no waiting. It sinks in within seconds and layers beautifully under any serum or moisturiser.

Clinically proven safe, even for sensitive and acne-prone skin.

Not just "dermatologist-approved" marketing language. This formula has undergone primary skin irritation testing, sensitive skin testing, and non-comedogenic testing on acne-prone skin.

150ml of actual, meaningful product.

Not the 30ml mini that runs out in three weeks. You're getting a generous, full-sized treatment — enough to genuinely see what six peptides can do for your skin over a complete skincare cycle.

Works at every stage of the routine.

Use it as a toner-step booster straight after cleansing, or layer it under your existing serum for an amplified multi-peptide effect.
