About this sunscreen
Mash Sunprotection Lotion SPF 45 is a chemical sunscreen built on an older filter set of Benzophenone-3, Octocrylene and Titanium Dioxide. It wears with a balanced finish, keeps white cast low and feels lightweight, and is generally low on pore-clogging. Protection is rated only moderate and the score is 48.3/100, so it is best treated as a basic everyday option rather than a high-protection pick.
