COSRX The Vitamin C 13
19000163791

Bright and fluid on the skin, this water-based serum focuses on dullness, uneven tone and visible discoloration. The lightweight texture absorbs without a sticky finish and supports a clearer-looking complexion while adding antioxidant care to a daily routine.

The formula contains 13% ascorbic acid together with 3-O-ethyl ascorbic acid for targeted vitamin C care. Glutathione and niacinamide complement the brightening effect, while panthenol, squalane and sodium hyaluronate help maintain comfort and hydration as the serum works on dark spots and signs of photoaging.

It is well suited to routines focused on luminosity, freckles, blemish marks and early signs of aging. With consistent use, skin is supported toward a more even, refreshed appearance without the weight of a rich serum texture.
