Loss of pigment?

I wonder if anyone else has the same prob as me. A while ago i got like a heat lump on my upper eyelid which i scratched and picked at ( stupid i know) and it turned into a little sore. I applied sudocrem and it eventually went but i am now left with a mark where it originally was. It looks like i have no pigment in my skin there anymore as it is kinda white/cream in colour. A friend of mine said i had caused trauma to the area by scratching etc and its happened because the eyelid skin is so tissue like? It looks worse now i have a tan as that area has not tanned. Anyone else had this?

sounds like vitiligo to me

Yes I have them all over my body where ive scarred in the past,check out vitaligo on the net,ie lack of pigment.
