Other forms: sunscreens
Sunscreen is the cream that protects skin from burning in the sun. Apply sunscreen, factor fifty sunscreen, reapply the sunscreen.
Most people use far less than the amount the factor number is tested with, which means the real protection is well below the label. It must go on before you go out and again every couple of hours. The factor measures burning rays only unless it says broad spectrum.
