Can just one chemical peel make that much of a difference in hyperpigmentation? I have PIH and I am mixed race but half white. I have had 15% TCA peels before and undergo light peeling but didn't notice much difference from those. If I go higher what type of peel should I try? Also for a 25%+ of TCA, glycolic, mandelic or lactic acid peel did you have much experience with lightening of PIH?
Glycolic can work, TCA can work if strong enough, especially if you bump up the percentage and can handle it on your skin. Have you tried alternating with skin bleach akaHydroquinone, and a peel a month. IF this doesn't work the next thing to bump upto is a photofacial aka IPL which works on certain colors of pigment (takes several treatments) for red you use V-beam vascular laser.
