COSRX's Alpha-Arbutin Discoloration Care Hydrogel Mask is a long-wear brightening treatment mask designed to be left on for 2–3 hours, or overnight, until the hydrogel sheet turns completely transparent — a sign that the active ingredients have fully transferred into the skin. The hydrogel format holds a significantly higher concentration of actives in contact with the skin for longer than a standard sheet mask, making it a step up in brightening results.

Alpha-Arbutin tackles dark spots and hyperpigmentation at the source, Niacinamide and Acetyl Glucosamine add brightening and texture-refining support, and Glutathione and Ferulic Acid provide antioxidant protection. A 5-type Ceramide complex alongside Cholesterol and Fatty Acids strengthens the barrier throughout wear, and 5 types of hyaluronic acid deliver sustained deep hydration. Low Molecular Weight Hydrolyzed Collagen (200Da) and Adenosine support firmness and elasticity. Fragrance-free. Each pack contains 3 individual sheets (approx. 34g per sheet).

Star Ingredients

Alpha-Arbutin – tackles dark spots, post-blemish marks and hyperpigmentation for a visibly clearer, more even complexion.

Niacinamide – brightens and refines skin texture with each use.

5 types of ceramide + Cholesterol + Fatty Acids – keep the skin barrier strong throughout the long wear time.

5 types of hyaluronic acid – deliver deep, layered hydration from the very surface to deeper skin layers.

Hydrolyzed Collagen (Low Molecular Weight 200Da) + Adenosine – support skin firmness and elasticity.

How To Use

After cleansing, apply toner or serum. Open the pouch, remove the films and apply the mask to the face. Leave on for 2–3 hours or until the mask turns transparent. Remove and gently pat in any remaining essence. No need to rinse.

Recommended Skin Type
