What is the difference between sunscreen and sunblock?
Sunscreen absorbs UV rays and scatters them. The shorter length of the rays makes them less dangerous. They are available in creams, gels and lotions, and once applied, aren’t noticeable. Sunblock reflects UV rays. At one time, the only form sunblock came in was a white, opaque gel, and it was noticeable from far away. More recent sunblock has active ingredients that are smaller and so no longer obvious when applied.
