I'm Asian and our skin tones are prone to PIH the extent of which varies with body area. My electrologist, like Seana, used equipment to minimise skin reaction. I also, along with my sister, undertook long facial sessions (say, 10 hours over 3-4 days). Neither of us however experienced noticeable PIH on the upper lip area despite having a lot of follicles treated in a short period of time. I guess what I'm trying to say is that it doesn't have to be this way to remove hairs, even if you have a tendency to PIH.
