I want to know if anyone has had a chemical peel or microdermabrasion on their face to treat any skin condition such as: fine lines and wrinkles, acne and acne scars, redness, large pores, etc, conditions that maybe couldnt be corrected by medication (as in my case) please answer only if you have had it or know someone who has, What happened? what were the results? How long did they last? What was the cost? thank you
