Around my mouth, I have all of these red marks from old zits and the such, and alot of redness as my face is very sensitive. Should I get an acid peel, or microderm kit to get rid of the discoloration? If so, what kind? Also, I need something under $40 that I can get easily, that won't hurt my already sensitive, acne prone, and allergic-to-benzoyl-peroxide, skin.. (a natural or over the counter solution to getting rid of the "ghost zits" (the red or dark purple marks after a zit) instead would be very lovely as well..) Oh and if this matters, just ignore my black avatar. This is my friends account =)
