COSRX The 6 Peptide Skin Booster Serum

Boost hydration, firmness, and overall skin radiance with COSRX The 6 Peptide Skin Booster Serum, a lightweight toner-like serum designed to help improve the look of fine lines, uneven texture, dullness, roughness, and loss of elasticity. Its fast-absorbing texture makes it an ideal first-step serum for daily use, helping prep the skin for the rest of your skincare routine without stickiness or heaviness.

Formulated with a 6 Peptide Complex, niacinamide, sodium hyaluronate, N-acetylglucosamine, allantoin, and adenosine, this multi-benefit serum helps support smoother, firmer, and more balanced-looking skin. The peptide blend helps target multiple early aging concerns, including elasticity, texture, and visible pores. Niacinamide helps improve the look of uneven tone and supports a brighter-looking complexion, while sodium hyaluronate helps draw in moisture for plumper, more refreshed-looking skin. Allantoin helps comfort the skin, and adenosine helps support a smoother appearance.

This booster serum is a great choice for anyone looking for a K-beauty peptide serum, first-step anti-aging serum, or a lightweight skin booster that helps support hydration, radiance, firmness, and texture all at once. It layers easily under ampoules, serums, and moisturizers, making it a versatile addition to both morning and evening routines.
