COSRX The Alpha-Arbutin 2 Discoloration Care Serum 50ml

Dark spots that linger after a breakout, a little too much sun, or simply time — this COSRX serum was made to tackle them head-on. No empty promises, just a verifiable list of active ingredients and results you can actually see over time. The slim 50 ml bottle fits seamlessly into any skincare routine without taking over.

Texture and actives — Alpha-Arbutin is dosed at 2% — a concentration rarely found in mainstream skincare — to work directly on existing melanin deposits. It's paired with Tranexamic Acid, Ferulic Acid, and Niacinamide, three ingredients that each play their part in evening out skin tone and protecting against oxidative damage. Madecassoside, derived from Centella asiatica, helps soothe any irritated areas. For hydration, the formula brings together Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, and Sodium Hyaluronate Crosspolymer — three forms of hyaluronic acid with different molecular weights, delivering moisture at both the surface and deeper layers. The texture feels smooth and lightweight, neither watery nor heavy, and absorbs cleanly with no residue.

How to use it — Apply the serum after cleansing, on clean skin that's still slightly damp to help it absorb. Spread it evenly across the entire face, or focus it on specific areas depending on what your skin needs that day. When particular spots need extra attention, the product directions suggest layering two to three applications one after the other, letting each one absorb before the next. It goes on before your moisturiser and, during the day, under your SPF — which is essential when you're working on skin tone.
