What is the primary function of a lip balm?

The primary function of a lip balm is to moisturize and protect the lips. Lip balms are formulated with a variety of ingredients that create a barrier on the surface of the lips, preventing moisture loss and keeping the lips hydrated. This is particularly important as the skin on the lips is thinner and more sensitive than other areas of the skin, making it prone to drying out and chapping. Ingredients like beeswax, shea butter, and various oils are commonly used in lip balms to provide both moisture and protection from environmental factors such as wind and sun exposure.

While some lip products may offer exfoliation or color enhancement, these are not the main purpose of traditional lip balms. Exfoliation is typically associated with products specifically designed to slough off dead skin rather than a moisturizing formula. Similarly, enhancing lip color is not a function of lip balm, which is primarily restorative rather than decorative. Lastly, removing makeup from the lips is the role of makeup removers or cleansers, not lip balm.
