What does SPF in tanning products stand for?

SPF stands for Sun Protection Factor. This measurement indicates the level of protection a tanning product offers against ultraviolet (UV) radiation, specifically UVB rays, which are primarily responsible for sunburn and contribute to skin cancer. The higher the SPF number, the greater the level of protection provided. For example, a product with SPF 30 allows you to stay in the sun 30 times longer without burning compared to using no sunscreen at all, assuming proper application.

Understanding SPF is essential for safe tanning practices, as it helps consumers choose the appropriate level of sun protection based on their skin type and the intensity of sun exposure. This knowledge is critical for promoting skin health and preventing damage from ultraviolet rays.
