About this sunscreen

Medicube No Cast Just Glow Collagen Sunscreen SPF 50 is a chemical sunscreen on an older-generation filter base of Homosalate, Octocrylene, Ethylhexyl Salicylate, and Avobenzone. As the name suggests, white cast stays low, and it wears lightweight with a balanced finish that works well under makeup. It sits low on the pore-clogging scale but may sting slightly for some users. With good protection and a score of 70/100, it is a comfortable everyday SPF 50 whose dated filters keep it out of the top tier.
