Melanin is a pigment that is produced by cells in the skin called melanocytes. It is responsible for the color of our skin, hair, and eyes.
The primary role of melanin is to protect the skin from harmful UV radiation. When skin is exposed to UV radiation, melanocytes produce more melanin, which helps to absorb and scatter the harmful rays, reducing the risk of sunburn and skin damage.
In skin care, melanin plays a role in the prevention of hyperpigmentation, which is the overproduction of melanin in certain areas of the skin that results in dark patches or spots. To prevent hyperpigmentation, it is important to protect the skin from UV radiation, avoid excessive sun exposure, and use products that help regulate the production of melanin, such as topical vitamin C and hydroquinone.
It is also important to be mindful of skin products that can cause skin irritation, as this can trigger the production of melanin and result in hyperpigmentation. In general, it is best to choose gentle, non-irritating skincare products, and to consult with a dermatologist if you have concerns about your skin’s appearance or health.
