Question: 1 / 400

What does SPF stand for in skincare products?

Skin Protection Factor

Sun Protection Factor

SPF stands for Sun Protection Factor, which is a measure of how well a sunscreen protects the skin from ultraviolet (UV) radiation, specifically UVB rays that can cause sunburn and contribute to skin cancer. Higher SPF numbers indicate a greater level of protection. For instance, an SPF of 30 means that it would take 30 times longer for the skin to start burning compared to not using any sunscreen at all.

In the context of skincare, understanding the correct term is essential for both professionals and clients when discussing sun safety and the effectiveness of sun protection products. The other listed options, such as Skin Protection Factor, Sun Prevention Factor, and Skin Performance Factor, do not accurately represent the established terminology relating to sun protection in skincare. These terms may imply different concepts that are not recognized in the context of sun protection.
