Sunscreens contain UV filters that block radiation from penetrating below the outer skin later, called the epidermis.
But over time, the filters themselves penetrate deeper into the skin, allowing more UV radiation in...the sun's damaging effect is multiplied when the sunscreen has been on too long.
Meanwhile, the scientists have passed along the advice of the Skin Cancer Foundation, which recommends reapplying sunscreen every two hours, and especially after sweating or swimming.
