SPF stands for Sun Protection Factor, the numeric value stating the level of effectiveness provided by sunscreen in preventing sunburn and other harmful conditions caused by exposure to the sun. While SPF specifies the level of protection from UVB rays, the new required testing and labels for Broad Spectrum sunscreen ensure that UVA protection also increases in tandem with higher SPF values. However, even high SPF products must be applied and reapplied according to the label directions in order to achieve and maintain proper sun safety.
