COSRX The 6 Peptide Skin Booster Serum

Why Does Your Skin Need a Booster?

Sometimes, moisturizer alone isn't enough. When skin feels dry, dull, uneven, or less smooth, your skincare routine may benefit from an extra first step that helps prepare the skin for what comes next.

COSRX The 6 Peptide Skin Booster Serum is a lightweight daily booster designed to be used at the beginning of your skincare routine. Its watery, fast-absorbing texture delivers refreshing hydration without leaving the skin feeling heavy or sticky.

Why Add It to Your Daily Routine?

The formula features a 6-Peptide Complex combined with Hyaluronic Acid, NAG, and Amino Acids to provide multi-benefit daily care.

Hydration – Helps replenish moisture for skin that feels dry or dehydrated.
Firmness & Smoothness – Peptides help support a smoother, firmer-looking complexion.
Skin Texture Care – Helps improve the appearance and feel of rough, uneven skin texture.
Pore & Sebum Care – Provides balanced care for skin concerned with visible pores and excess oil.
Even-Looking Complexion – Helps skin appear fresher, smoother, and more refined.
Skincare Prep – An ideal first serum step before applying your favorite essence, serum, or moisturizer.

What Makes It Different?

Instead of adding another heavy serum to your routine, this booster provides multiple skincare benefits in one lightweight step.

It is especially useful when your skin needs more than basic hydration but you still want a product that feels light enough for everyday use.

Think of it as a “first-step booster” that helps create a hydrated, smooth foundation for the rest of your skincare routine.
