The efficacy score is driven mainly by 15% L-ascorbic acid near the top of the formula plus vitamin E, which is a well-supported antioxidant pairing for brightening and oxidative protection; the score is pulled down because the formula is fragrance-containing and otherwise fairly straightforward, with no extra evidence-backed support system beyond a standard emollient/solubilizer base.
