Sunscreens with SPF 30, 50, 70, or 100 offer different levels of defense against the sun’s dangerous UV rays. Initially, UVB rays were thought to be the only UV rays to worry about, since they are shorter in length and cause sunburn.

UVA rays can penetrate clouds, fog and glass, and [the DNA] changes from these rays hitting your skin can be lifelong,” Dr Gregory Bays Brown, founder of ReVive skincare, tells WIRED.One of the first arenas that I’d really like to clear up for you is the differences between physical and chemical sunscreens.
