About this sunscreen
Intradermology Synergy 6 Nx-gen SPF 50 is an older-generation chemical formula using Butyl Methoxydibenzoylmethane, Ethylhexyl Methoxycinnamate, Octocrylene and titanium dioxide. It keeps white cast low, feels lightweight with a balanced finish, and is low on pore-clogging, though it can sting moderately near the eyes. Protection is good and it works well under makeup. With a score of 63.8 out of 100, it is a middling pick that sits well under makeup but relies on an older filter blend.
