This is very interesting you took these videos as an example. On hairtell, there are sadly “famous” as “Marquis de Sade” clinic (as far as I remember if I am not wrong).
For the big majority of doctors in France, scars are completely normal after electrolysis hair removal treatment (by them, since only doctors can provide this treatment according to the law).
One of my French client was disfigured after some electrolysis sessions by a dermatologist located in the south of the country. Now she get better and she is happy about the results.
I spoke with several dermatologists and all told me that scars occur with electrolysis. This is why almost all prefer providing laser hair removal.
An other interesting case : I contacted an other French physician, who was mtf transgender. She was doing electrolysis for her beard (white hair) by an dermatologist. She has a lot of scars on her face, pretty bad. But as a physician herself, she thought this is normal... I tried to convince her, but doctors don’t like to be wrong...
