The 6 Peptide Skin Booster

Boost your routine from the very first step with COSRX The 6 Peptide Skin Booster.

This lightweight yet powerful pre-serum is formulated with a concentrated blend of six potent peptides that target multiple skin concerns at once - texture, enlarged pores, fine lines, and loss of firmness. It works like a performance primer for your skincare, enhancing absorption and helping every product that follows work even better.

With a water-light texture that sinks in immediately, this peptide booster helps improve elasticity, refine uneven texture, and promote a smoother, healthier-looking complexion without irritation. Over time, skin appears more refined, balanced, and resilient, with minimised fine lines. 

150ml
