A popular summer trend of freezing sunscreen for a cooling effect has been debunked by a pharmacist, who warns that this practice can render the product ineffective and potentially dangerous. According to the expert, sunscreen lotions are formulated with two distinct phases—an aqueous and an oily phase—that are carefully homogenized to ensure even protection. Freezing these creams causes these phases to separate, compromising the integrity and protective capabilities of the sunscreen. "If you freeze them, they separate, and then they lose their properties and are useless," explained the pharmacist in a recent video. He further added that even if one were to freeze sunscreen, it would quickly thaw upon arrival at the beach, offering no practical benefit for cooling and, more critically, no adequate sun protection. Consumers are advised to store sunscreen according to manufacturer instructions, typically in a cool, dry place, to maintain its efficacy and ensure proper protection against harmful UV rays.
