Tanning lotion is a cosmetic product designed to enhance the skin's appearance by promoting a bronzed look. It typically contains ingredients that either accelerate the tanning process or provide a temporary color. Many formulations include moisturizers to keep the skin hydrated and may also contain sun protection factors (SPF) to shield against harmful ultraviolet (UV) rays. There are two main types of tanning lotions: self-tanners, which create a tan without sun exposure, and sun tanning lotions, which are used while sunbathing. Users should choose a product based on their desired results and skin type, ensuring safe and effective tanning practices.
