Choosing the Best SPF in Sunscreen

SPF stands for Sun Protection Factor. The higher the SPF number, the better protection against the sun's harmful UVB rays. The SPF number lets you know how much longer you can stay out of the sun without burning. For example, if it takes 15 minutes for a person to burn, an SPF 15 will allow them to stay out in the sun 15 times longer without burning.

How High Should SPF Be?

Experts recommend an SPF 15-30 with UVA and UVB ray protection. Higher SPFs provide only a smaller amount of protection (about 1-2%).

Fair skinned people who are sensitive to the sun may want to choose an SPF of 25-30. People with darker or olive toned skin should buy an SPF15 or higher to protect from burning. Keep in mind that darker skin is not immune to the damaging effects of the sun. It may not burn as easily, but is still affected by the sun's rays.

Experts recommend an SPF 15 with "broad spectrum" protection for daily sunscreen use.

It is important to follow manufacturer's instruction for application.
