@explainingall: Through a UV camera, sunscreen appears as a dark or black layer on the skin. This is because sunscreen is designed to absorb and block ultraviolet (UV) light, preventing it from reaching the skin. UV cameras capture light beyond the visible spectrum, revealing how well a sunscreen blocks UV rays. Areas covered with a sufficient layer of sunscreen look dark, while uncovered skin appears lighter since it reflects UV light. This effect highlights the effectiveness of sunscreen in protecting against UV radiation. #sunscreen #LearnOnTikTok #explainingtheuniverse
