35yrs old - 5ft 10inches. I developed psorisis after a chemical contact with my skin in a sensitive area (hence no photos). This dryness went on for a number a weeks and as a result the area lost pigmentation and has being referred to possibly being in a vitilago state because of the time that has passed. I wonder if there are any treatments or light based treatments etc which could be tried to achieve even tone again or pigment restoration.
