This may sound similar a question you don't think bears repeating (because, uh, y'all've heard information technology a million times), merely it absolutely does.

She explains that these changes happen when UV calorie-free hits skin unprotected by sunscreen, causing DNA changes at a cellular level in the dermis (aka the deepest layer of the skin).
Sooo what does this hateful? Well, information technology can take a long time for this damage to become visible (read: years)—only once information technology does, that'due south when y'all can begin to notice common repercussions of UV damage (i.e., premature wrinkles, dark spots, uneven skin texture, and potentially fifty-fifty pare cancer).

Typically, chemical sunscreens are more water- and sweat-resistant, making them corking for agile lifestyles and likewise for virtually skin types, explains Dr. Chiu.
