Unlike lightly pigmented white skin, people of color like; ethnic Africans, East Indians and Pakistanis often suffer from uneven skin tones. They are also more prone to marks, spots, and darkened skin patches or hyperpigmentation, considerably more so than their lighter skin counterparts.
This hyperpigmentation occurs because of the increase number of melanin producing cells in dark skin and these cells are easily stimulated. So, any condition or event like trauma that affects the skin can readily cause an uneven release of the pigment Melanin leading to the dark spots. Scrapes, pimple squeezing, prolonged sun exposure, or mechanical trauma all have the capacity to cause hyperpigmentation in dark skin. Even normal aging can lead to hyperpigmentation in African Americans, also known as being “two toned”. However, most hyperpigmentation occurs within the surface layers of the skin. As such it can easily be removed by the cosmetic procedure of microdermabrasion which gently exfoliates and removes the top-most layer of skin. Also removed in the top most layer of skin are dead skin cells, dirt and debris to leave behind supple, fresh, younger looking skin.
