Hello,
After reading your post, I feel that the lesion that you are having is due to scarring and pitting of the skin which is a rare side effect of electrolysis and occurs due to carelessly or rapidly done electrolysis or due to the sensitiveness of the skin to electrolysis.
TCA peels can significantly improve freckling, blotchy or uneven pigmentation
and shallow acne scars. Laser treatment also helps in diminishing the scars.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
