Pigmentary Disorders
The colour of the skin is affected by skin pigmentation disorders. Some pigmentation diseases affect only specific areas of the skin, while others affect the entire body. Skin that has too much melanin is dark, whereas skin that has too little melanin is pale. Skin darkening can be caused by Addison's illness, pregnancy, or sun exposure. Vitiligo, on the other hand, produces lightening of skin regions. Albinism is a skin-color-related genetic disease. A person with albinism may be colorblind, have skin that is lighter than normal, or have patchy skin that is missing colour in particular areas. Albinism, Melasma, Pigment Loss After Skin Damage, and Vitiligo are some of the most common pigmentary disorders.
