A product with an SPF of 15, for example, would allow you to stay in the sun without burning 15 times longer than if you didn't apply sunscreen.A number indicating the degree of protection provided by a sunscreen product against the ultraviolet rays of the sun.A measurement of the effectiveness of sunscreen in blocking ultraviolet B (UVB) light. Protection from the sun is essential in the prevention of skin cancer and other skin damage. Doctors recommend sunscreens with a sun protection factor (SPF) of at least 15. They are available in sprays, gels, creams, and wax sticks. Fair-skinned people require sunscreens with higher SPFs. A high SPF indicates better protection from the effects of UVB light, which causes sunburn and an increased risk of skin cancer. However, SPF does not refer to the level of protection against the effects of ultraviolet A (UVA) light, which enhances the damaging effects of UVB. Consequently, it is best to choose a broad-spectrum sunscreen that also offers UVA protection. Sunscreens must be reapplied every 2 hours, especially if a person is swimming or sweating.An indicator of the extent to which a sunscreen absorbs UVB radiation, determining the level of defense it offers against sunburn. This measurement is expressed as a numerical value known as the SPF (Sun Protection Factor) number, where a higher SPF signifies enhanced protection. The SPF number indicates how much longer a person can stay in the sun without experiencing a sunburn."}
