Melanin play an important role in pigmentation or depigmentation of skin. If body produce too much melanin it causes hyper-pigmentation and in inverse case if produces low melanin it causes hypo pigmentation in skin.
Hypo-pigmentation or depigmentation, ratio of such problems is less than that of hyper-pigmentation problems. Normally such skin condition causeswhite patches on skin.
In depigmentation the skin becomes lighter as compared to its surrounding.Example of skin condition causes depigmentation are nevus depigmentosus (quite stable scars may appear any part of body), Pityriasis Alba (a common condition in children), Idiopathic guttate hypomelanosis, vitiligo andwhite scars due to injuries.
