hi this is from webmd. your doctor can usually make the diagnosis of vitiligo during a physical exam. there is no known way to prevent or cure vitiligo. however several methods including cosmetics re-pigmentation using uv light therapy corticosteroid creams depigmentation of unaffected skin areas and skin grafting can be used to improve the appearance of skin severely affected by vitiligo. some people go through there whole life with this they even get it on there faces i don't think there was a cure but as you can read there is a chance. but on your penis are you a naturist by any chance? good luck
is there anything that can aid in gaining back lost skin pigmentation? . i had an allergic reaction in which resulted in the loss of skin pigmentation on my penis. it has been several months now and although the reaction has gone away the lost pigmentation has not returned. is there anything (ointment etc. ) that could aid in this?
