About this sunscreen
Skin Authority Age Defying Moisturizer SPF 18 is a moisturiser with chemical sun protection from an older filter blend (avobenzone, ethylhexyl methoxycinnamate, ethylhexyl salicylate and benzophenone-3). It keeps white cast low with a balanced finish and stays lightweight, with low pore-clogging potential and an okay showing as a makeup base. Its low SPF 18 and moderate measured protection are the main limits, and the score of 58.7/100 reflects a light daily moisturiser rather than dedicated sun defense.
