Are sun protection sprays waterproof?

Sun protection sprays may have varying degrees of water resistance, but no sunscreen is entirely waterproof. Some sun protection sprays are labeled as "water-resistant," indicating that they maintain their effectiveness for a certain amount of time when exposed to water. The level of water resistance is typically specified on the product label, stating the duration (such as 40 or 80 minutes) for which the sunscreen remains effective while swimming or sweating. It is important to note that water resistance does not mean the sunscreen is impervious to water, and it will eventually wear off. To ensure continuous protection, reapply the sun protection spray after swimming or towel-drying, even if it claims to be water-resistant.
