The efficacy score is driven by its ability to dissolve makeup, sunscreen, and excess sebum through a high-oil, ester-rich formula with emulsifiers that should rinse cleanly; it is not boosted by vitamin E because that is a minor support ingredient in a rinse-off cleanser, and the added fragrance slightly lowers the safety score.
