System Verdict
Decent hydrating moisturizer with a modest brightening claim, not a true vitamin C treatment. The efficacy score is held back because the main brightening active, 3-O-Ethyl Ascorbic Acid, sits mid-list rather than dominating the formula, so this is more of a supportive antioxidant/hydration cream than a high-powered brightening product. Glycerin and polyglutamic acid do real work for hydration, and the emollient base is sensible, but there is no evidence of a high-dose, low-pH vitamin C system or any stronger treatment actives.
