Vitiligo is a skin disorder in which melanocytes are destroyed. These are the skin cells which make a brown pigment called melanin that colors our skin. Without melanocytes, skin pigment can't be made. The pigment is characteristically lost in patches, producing a mottled appearance, although the patches may enlarge over time.
I've had vitiligo on my hands and forearms for several years. I'm lucky, since because my skin is pale the white patches are really only noticeable in summer if the rest of my skin turns darker, and even then they are not very obvious except in certain light conditions. For people with darker skin, or for people who have vitiligo in a more visible place, such as the face, the vitiligo may be much more problematic. The darker the skin, the more obvious the contrast between the light patches and the dark skin. Another advantage that I have is my vitiligo is progressing fairly slowly. Each summer I notice that it has spread a little further over my hands and forearms. In some people the disorder progresses much more rapidly.
The cause of the melanocyte mac makeup wholesale destruction in vitiligo isn't known for certain, but it may be due to an autoimmune problem. Our immune system normally destroys bacteria and viruses. In an autoimmune disease the immune system mistakenly attacks the body's own cells. It's thought that in vitiligo the immune system destroys or injures melanocytes, causing a loss of skin pigment.
Vitiligo Symptoms and DiagnosisThere are three possible patterns of depigmentation in vitiligo (although sometimes additional classifications are used). wholesale mac makeup In a focal pattern there are only a few areas without pigment, or there may be only a single depigmented patch. In a segmental pattern depigmentation occurs on only one side of the body. The most common type of vitiligo, which I have, is known as generalized vitiligo. In this type the depigmentation develops symmetrically on both sides of the body. For example, my hand and forearm on each side of my body are affected.
