System Verdict
This is a decent antioxidant serum, not a true vitamin C powerhouse. The efficacy score is limited by the use of ascorbyl glucoside instead of a more potent direct vitamin C form, and most of the formula is built around supportive antioxidants, peptides, and humectants rather than a high-strength, clearly doseable treatment active. It should help with mild brightening and antioxidant support, but the formula does not suggest a dramatic correction product, and the final performance depends on the actual ascorbyl glucoside percentage and pH, which are not disclosed here.
