What is the primary purpose of a bronzer in tanning?

The primary purpose of a bronzer in tanning is to provide an immediate cosmetic color that enhances the appearance of the skin during and right after the tanning process. This type of product contains pigments that give the skin a darker appearance upon application. The effects are temporary, meaning that these colorants can be easily washed off with water, highlighting their use as a surface enhancement rather than a permanent change.

While other options may address aspects related to tanning, such as the longevity of a tan, UV protection, or skin hydration, those functions do not align with the primary purpose of a bronzer. A bronzer is specifically designed to provide a quick boost of color rather than to enhance or extend a tan or to offer any protective or hydrating benefits to the skin.
