What is the primary function of melanin in the skin?

Melanin primarily functions to absorb UV radiation, protecting the skin from the harmful effects of the sun's rays. When the skin is exposed to UV light, melanin absorbs this radiation and helps prevent damage to the DNA in skin cells, which can lead to skin cancers and other skin disorders. This protective mechanism is particularly important for reducing the risk of sunburn and photoaging.

Understanding the role of melanin is crucial for estheticians as it highlights the importance of sun protection in skincare routines, especially for individuals with different skin tones. The amount and type of melanin produced in the skin can vary widely among individuals, influencing their pigmentation and susceptibility to sun damage.
