The COSRX The 6 Peptide Skin Booster Serum is a lightweight first-step treatment designed to improve skin texture, boost hydration, and support overall skin health. Formulated with a 6-peptide complex, this multi-functional serum helps target common concerns such as dullness, enlarged pores, uneven texture, and early signs of aging.

Its fast-absorbing, water-like texture prepares the skin to better absorb the products that follow, making it an ideal first step after cleansing.

Key Benefits

Improves skin elasticity
Peptides help support collagen production and reduce the appearance of fine lines.

Refines pores and controls oil
Targeted peptides help regulate sebum production and improve the appearance of enlarged pores.

Brightens and smooths skin
Ingredients like copper tripeptide and oligopeptides help improve skin tone and texture.

Soothes sensitive skin
Peptides such as palmitoyl tripeptide help calm irritation and support the skin barrier.

Who It’s For

Ideal for anyone experiencing dull skin, uneven texture, enlarged pores, or early signs of aging. Suitable for all skin types, including sensitive skin.

How To Use

After cleansing, apply a small amount to the face as the first step of your skincare routine. Gently pat into the skin until absorbed, then follow with toner, serum, and moisturizer.

Pro Tip

For extra hydration and a smoother “glass skin” finish, apply two to three thin layers before continuing with the rest of your routine.
