I'm a 20 year-old Indian girl with olive skin and thick hair. ha laser hair removal when I was 17(I had12sittings) and I noticed moderate hyperpigmentation around legs and underarms I stopped with laser sessions. I have many ingrown hairs on legs which are not in the form of inflamed raised bumps, but are like brown spots with hair trapped deeper under the skin it's impossible to squeeze the hair out. My hyperpigmentation has reduced, I apply Tretinoin(0.025%).
