Everyone desires flawless clear skin and perfect complexion. But factors such as free radicals, hormonal changes and sun exposure can damage your skin leading to patchy pigmentation and dark spots, making you look older.
Our skin has melanocytes. These are cells that produce pigment called melanin which gives skin its color. The number of melanocytes present in our skin determines our skin colour. Melanin apart from giving skin its color, protects our skin from the damaging effects of sun radiation. The more our skin is exposed to sunrays, the more melanin is produced by melanocytes. This excess melanin is then deposited under the skin, which leads to skin tan, darker patches or pigmentation.
