SPF, which stands for Sun Protection Factor, is a common term used to refer to the measure of how well a sunscreen product protects the skin from harmful UV radiation. However, there are several synonyms for the term SPF that one can use in the context of sun protection. These include sunblock, sun cream, sun lotion, and UV protector. While the term SPF is commonly associated with the numbers that indicate the level of protection in sunscreens, these synonyms can help diversify the language used when discussing sun protection products. No matter what term you use, it's important to prioritize sun protection to keep your skin healthy and safe.
