What function does lip balm serve during tanning sessions?

The primary function of lip balm during tanning sessions is to protect the lips from drying and burning. Tanning, whether through sun exposure or artificial tanning methods, can lead to skin dehydration and increase the risk of sunburn, particularly on sensitive areas like the lips.

Lips have thinner skin compared to other parts of the body, making them more susceptible to damage from UV rays or heat. Applying lip balm creates a barrier that helps to lock in moisture, preventing excessive drying and reducing the risk of chapping or burns. This protective measure is essential because the lips lack oil glands and are unable to produce moisture on their own, making them vulnerable during tanning sessions.

While some lip balms may offer a slight enhancement to color or a pleasant fragrance, their primary purpose in this context is to maintain hydration and provide protection.
