The stimulation of melanocytes in the skin leads to the development of pigmentation. Melanocytes are the cells that release melanin, which is the pigment you can see in your skin after being in the sun and a tan is developing. Different skin types are more prone to producing patches of pigmentation, and these can be stimulated by changes in hormones, trauma, and chemical alterations to the skin. Treatment methods for pigmentation patches will vary depending on the individual involved but they can include topical creams and laser treatments. Often referred to as sun spots, age spots and liver spots, pigmented lesions are often a concern for people who are looking at clearing their complexion. These can be easily treated for those people who are committed to staying out of the sun and wearing sunblock. After professional diagnosis, pigmented lesions can be treated and maintained long-term.
