Hi, I have used salicylic acid face wash heavily along with Benzoyl Peroxide, my skin type is really sensitive. My under eyes have gonna really red and burt and left me with deep wrinkles when smiling, one of the eyes have completely recovered as it didn't have much deep wrinkles, although the other eye looks really wrinkly and the wrinkles look deep, I am only 21 and my skin was like baby's skin, didn't have any wrinkles before the bp use.
