About this sunscreen
Lancaster Sun Silky Milk SPF 15 is a chemical sunscreen on a hybrid filter blend including octinoxate, avobenzone and Uvasorb HEB. The silky milk wears lightweight with a matte finish, keeps white cast low and layers well under makeup, but it tends to sting noticeably near the eyes. It is low in pore-clogging potential, so it is generally acne-friendly. Scoring 58.8/100 with moderate protection at only SPF 15, it is a light option best suited to low-sun days.
