About this sunscreen
Pharmaclinix Sun Blockex is an SPF 50 sunscreen that pairs mineral Titanium Dioxide with an older-school chemical filter blend including Octocrylene and Avobenzone. It keeps a low white cast with a balanced, lightweight finish, though the medium sweat-sting rating suggests keeping it clear of the eyes. With good protection and a lower score of 63.2/100, it is a basic option that trails the stronger picks in this group.
