Key Ingredients

Here’s what powers the Cos De BAHA Tranexamic Acid Nacinamide Serum:

Tranexamic Acid

A well-known brightening ingredient used to target dark spots, acne scars, and uneven skin tone. This serum contains 5% Tranexamic Acid, a concentration commonly loved in K-beauty routines for visible brightening without strong exfoliation.

Rich in antioxidants that help protect skin from environmental stress while supporting calmer-looking skin.
