Suntan lotion is a common term used for a lotion or sunscreen used to protect the skin from the sun's harmful rays. However, there are a variety of other synonyms that can be used to describe this product. Some common alternatives include sunblock, sunscreen, sun cream, sun lotion, and UV protection. These terms essentially describe the same product but may have slightly different variations in terms of formula, consistency, or texture. Regardless of the terminology used, it is crucial to use a proper sun protection product to protect the skin from sun damage, including premature aging and skin cancer.
