Product Details Brand: The Ordinary Key Ingredients: Alpha Arbutin (2%) and Hyaluronic Acid (HA). Size: 30 ml / 1 fl. oz. Main Benefits Fades Dark Spots: Alpha Arbutin is a safe skin-brightening ingredient that helps reduce the look of spots and hyperpigmentation. Evens Skin Tone: It works by inhibiting tyrosinase, an enzyme that helps with melanin production, leading to a more uniform complexion. Hydrating: The addition of Hyaluronic Acid ensures the serum is hydrating and helps the skin retain moisture, preventing the "drying" feeling some treatments can cause.
