The efficacy score is driven by the mineral UV filter zinc oxide plus a silicone/ester base that should help spreadability and film formation; the added humectants can improve comfort, but the botanical extracts, ascorbic acid, and tocopherol are present too low to materially change performance, so they do not push this into elite territory.
