What does melanin provide to the skin?

Melanin is a natural pigment found in the skin that is responsible for the color or tone of the skin. It plays a crucial role in protecting the skin from ultraviolet (UV) radiation by absorbing harmful rays and reducing the risk of DNA damage that can lead to skin cancer. The amount of melanin produced by melanocytes, which are specialized cells in the skin, determines the varying shades of skin color among individuals.

In contrast, smoothness pertains to the skin’s texture and is influenced by factors like exfoliation and hydration. Elasticity refers to the skin's ability to stretch and return to its original shape, largely dependent on collagen and elastin. Hydration involves the moisture content of the skin, which is affected by the skin's barrier function and the application of moisturizers. None of these factors directly relate to the role of melanin in providing pigment to the skin.
