Thank you for the update. There isn’t anything about the treatment that sounds concerning. We sometimes have to treat follicles twice, and the tugging could simply be your electrologist trying to remove the hair and realising it needs to be treated again. Treating follicles on the face is usually more painful or uncomfortable, but if your electrologist had truly overtreated you, it would be quite obvious with your skin reaction immediately following treatment.
Where most clinics say “redness fades within a day”, they’re typically referring to the very apparent “sunburnt” look that appears across the treatment area. You can expect redness around the treated follicles to persist for a few days, to a week or more depending on several factors.
Any discolouration remaining after that point is, as you say, PIH, which I can see on both sides of your face. PIH is basically a guarantee for every client to at least some degree. Some will get it worse than others due to ethnicity and skin tone, the energy levels during treatment, the area being treated etc. Some will only have mild PIH. The good news is that it always fades over time, and you don’t need to do anything to fix it.
As others said above, you have nothing to worry about. If you want to prove it to yourself, you can wait for your skin to return to normal before you continue with any more treatments.
