So I had a really severe bout of chicken pox last year. It left a lotta marks all over my body, in spite of me not touching/scratching it. Now while rest of the body is not an issue, there's this little patch in my face where it looks like my skin has been eaten out and there's some discoloration. It's stayed like that for the whole year. I don't know how to get rid of this, can someone please help?
