Sometimes when we get too much sun or have a hormonal imbalance, we get something called hyperpigmentation which is when our melanocytes get kicked into overdrive and they leave brown marks behind such as freckles, age spots, dark marks, etc. Vitiligo is the complete opposite. Vitiligo occurs when melanocytes no longer produce pigment, therefore they leave white splotches behind on the skin. Usually Vitiligo is prominent on the face, hands and wrists. The patches of depigmentation usually start out small, but they often enlarge and change shape over time. Vitiligo can affect all races, but it more noticeable in those with darker skin tones. Unfortunately there is no cure for Vitiligo, but there are products out there that can help cover the unpigmented spots. Dermablend Cosmetics and Exuviance Coverblend products specialize in covering up imperfections such as scarring, uneven pigmentation, birth marks and rosacea.
