MELANIN

Description

Melanin is a complex biopolymer pigment naturally produced by melanocytes in the skin, hair, and eyes. It plays a crucial role in protecting the skin from harmful ultraviolet (UV) radiation and free radical damage. There are two primary types of melanin: eumelanin, responsible for brown and black pigmentation, and pheomelanin, which produces red and yellow hues.

In skincare formulations, melanin is utilized for its photoprotective and antioxidant properties. It can absorb up to 99.9% of UV radiation, making it an effective natural sunscreen ingredient. Melanin also helps neutralize reactive oxygen species, reducing oxidative stress and minimizing cellular damage.

Synthetic melanin and melanin-like compounds have been developed for use in cosmetic products. These ingredients aim to enhance the skin's natural defense mechanisms against environmental stressors and promote a more even skin tone. Some formulations incorporate melanin precursors or tyrosinase inhibitors to modulate melanin production within the skin, addressing hyperpigmentation concerns.

When formulating with melanin or melanin-related compounds, it is essential to consider stability, bioavailability, and potential interactions with other active ingredients to optimize efficacy and safety in skincare products.
