Sun protection factor (SPF) is a number on sunscreen labels that shows how long skin can be in the sun and maintain a low risk for sunburn. The higher the SPF number, the longer it protects a person from the sun's burning rays.
It is important to read the information on the sunscreen label about the SPF factor listed on the label and how much protection it gives the skin. The sunscreen should be applied according to the directions on the label so it is most effective in protecting the skin from the sun's ultraviolet rays.
No sunscreen gives total protection, but "broad spectrum" sunscreens that contain ingredients such as avobenzone, benzophenones, cinnamates, salicylates, sulisobenzone, titanium dioxide and zinc oxide usually protect from ultraviolet A and B (UVA and UVB) rays. The label of the sunscreen product will say what types of UV rays it protects the skin from.
Sweating heavily, swimming or doing other water activities reduces the SPF because sweat or water on the skin will reduce the amount of protection the sunscreen provides. Sunscreen needs to be reapplied more frequently during these activities.

Avoid controversial sunscreen ingredients. Some (not all) researchers have raised red flags about two absorbable sunscreen ingredients: oxybenzone and retinyl palmitate (a form of vitamin A). Both are found in hundreds of sunscreens. The concerns? Very briefly, oxybenzone, which has been used in sunscreens as a partial ultraviolet A/ultraviolet B (UVA/UVB) shield since 1978, has been called a hormone disrupter that mimics the effects of estrogen in lab studies. Retinyl palmitate has triggered genetic mutations when exposed to sunlight in the lab. In other words, one or both might have a cancer connection. The dangers of these ingredients have been disputed by the American Academy of Dermatology and others.
