What Causes Hyper Pigmentation?
Melasma appears most often because of hormonal changes (pregnancy or birth control pills, for example) and disappears after child birth or once you stop the birth control treatment. Freckles are also signs of uneven skin pigmentation and can appear anywhere on the body, especially on the face, cleavage and hands. Freckles are usually inherited from parents. Some forms of skin hyperpigmentation may be the result of acne or other skin conditions that could leave colored marks on the skin after healing. Cosmetic surgery, burns or injuries can also cause hyperpigmentation. Another cause of hyperpigmentation may be drug treatment with amiodarone, tetracycline, minocycline, bleomycin, cyclophosphamide, chloroquine and quinacrine. If you have a history of taking any of these drugs and have uneven skin tone, it would be best to see a dermatologist.
