I have lots of dark spots on my body from ingrown hair. I exfoliate abt 3x a week and this helps to keep the spots lighter. Plus, i use kojic soap for overall exfoliation. I have used bleaching creams on my stomach. The spot lighten but not disappear. I also used two 18% TCA peels on my stomach area. The spots are lighter but the skin in the area became a lil darker. i also I experienced a chemical burn and have an addtional triangler scar. This was a home peel. Suggestions?
