What is a common benefit of using after-tan moisturizers?

Using after-tan moisturizers is beneficial primarily because they help prolong and enhance the tan. These products are designed to hydrate the skin, which can become dry after tanning. When the skin retains moisture, it maintains the depth and richness of the tan, allowing it to last longer. Additionally, many after-tan moisturizers contain ingredients that can enhance the appearance of the tan, providing a healthy glow and minimizing the potential for patchiness or fading.

The other options do not accurately portray the purpose of after-tan moisturizers. Some may mistakenly think that these products would eliminate a tan completely or solely exist for hydration, overlooking their role in maintaining and enhancing the tan. Furthermore, the idea that after-tan moisturizers would increase the intensity of UV rays is false, as they are not meant to increase UV exposure but to support skin health post-tan. This role of enhancing and prolonging the tan gives a clear advantage to using after-tan moisturizers.
