The 6 Peptide Skin Booster Serum

Multi-Concern All-in-One Peptide Booster

Imagine: one serum that combines six powerful peptides to address multiple skin concerns simultaneously. The COSRX The 6 Peptide Skin Booster Serum has the light, watery texture of a toner — but the potent power of a concentrated serum. It absorbs instantly, is non-sticky, and leaves your skin stronger, smoother, and more radiant every day.

What does this serum do for your skin?

• Fine lines & wrinkles — Firmer and more elastic thanks to the 6 Peptide Complex
• Loss of radiance — Visibly more glow and vitality with Niacinamide
• Uneven skin tone — Refined and more even with Hyaluronic Acid & Peptides
• Sagging skin — Visibly lifted and firmer thanks to Peptide Blend & Adenosine
• Rough texture — Smoother skin surface with Panthenol & Peptides

Why choose 6 peptides instead of 1?

Most serums contain only 1–2 peptides targeting a single concern. The COSRX The 6 Peptide Booster serum simultaneously addresses pores, sebum, firmness, tone, texture, hydration, and soothing — in one light, non-sticky formula suitable for all skin types.

Suitable for

All skin types, especially skin with multiple concurrent concerns such as fine lines, uneven texture, and loss of firmness.
