COSRX The Alpha-Arbutin Discoloration Care Hydrogel Mask is a hydrogel mask designed to brighten, even out, and smooth the complexion, ideal for dull skin, pigmentation spots, or acne scars. The formula featuring Alpha-Arbutin, niacinamide, N-acetylglucosamine, low-molecular-weight hydrolyzed collagen, hyaluronic acid, ceramides, and soothing ingredients delivers comprehensive care for radiance, hydration, and refined texture. As it works, the mask turns transparent, signaling that the essence is gradually absorbed by the skin, leaving the complexion fresher, clearer, and more radiant. Benefits: Helps reduce the appearance of pigmentation spots and acne scars. Visibly evens out skin tone. Imparts radiance to dull skin. Leaves skin smoother, more hydrated, and more comfortable. Helps refine the appearance of pores. Supports a clearer, fresher, and more radiant look. After cleansing, apply toner or serum. Open the pouch, remove the protective films, and place the mask on the face. Leave on for approximately 2–3 hours or until it turns transparent, then remove and gently massage in any remaining essence until fully absorbed. For more intensive results, it can also be worn overnight. During the day, follow up with a sun protection product.
