The 6 Peptide Skin Booster

COSRX's The 6 Peptide Skin Booster is a multi-tasking serum designed to improve overall skin condition by targeting elasticity, texture, pores, and hydration in one simple step. Infused with a powerful 6 Peptide Complex, this serum helps support collagen production, refine skin texture, and promote a firmer, smoother appearance over time. Its lightweight, fast-absorbing formula makes it especially suitable as a first-step booster, preparing the skin to better absorb the products that follow.

To brighten and balance the complexion, the formula includes niacinamide, which helps perk up dull skin, even out skin tone, and support pore and sebum care. For lasting comfort and hydration, hyaluronic acid delivers moisture deep into the skin, while allantoin helps soothe and calm, making the serum gentle enough for daily use. Together, these ingredients work to strengthen the skin barrier and maintain a healthy, well-balanced complexion.

Designed to layer seamlessly with other active ingredients, COSRX The 6 Peptide Skin Booster fits easily into any skincare routine and works well alongside exfoliants, vitamin C, or retinoids. Dermatologically tested and suitable for a wide range of skin types, this all-in-one booster leaves skin feeling hydrated, smoother, and more resilient with a visibly refined and refreshed look.
