I used electrolysis, and that had no negative effects. My hair was/is too light for laser hair removal.

it will be fine. maybe won’t be able to go out in the sun for a day or so, maybe a little redness or sensitivity but nothing major. your technician will advise you of the side effects before hand. No big deal for hair removal though

Permanent hair reduction is effective. I have had laser on my face for another reason, and I don’t have scars.
