I don't know if you can change the coloration in your skin. But my kids suffer from server eczema and I use a product calle skin-e-dip. I bought it on line at skin-e-care.com It has done miracles for them. My son will let his feet get to the point of cracked and bleeding he is limping and with the cream in one day he is walking better and in a week it is almost cleared up. The cream is amazing! I reccomend it to everyone. They have an affiliate program and I am looking into becoming an affiliate. Take care
