I also removed a mole with ACV and it left a red spot for quite some time. I found that applying VCO daily and a little Lugols occasionally helped to fade it. It is hardly noticeable at all now. And I expect it to disappear completely eventually.

I will advice u that as your spot in the face to treat it the best u can.

I would use a cream that is cheap (6 euros) and called bepanthol has provitamin B5 which has the property to regenerate skin. They use it with tattoo's so to avoid scaring.

Also this cream hydrates your skin.

Next I would do a research to find and another maybe more expensive and better cream something with aloe vera or similar herb to use with conjuction.

Do it.

You want to have the minimal scar possible. Creams and massage will avoid the scaring.

Don't use Iodine - it isn't a scar and you don't want to dehydrate it more or to peel a skin layer deeper. If was this spot to your body it wouldn't be such a prob but now it's your face.

Massage the spot with that creams.

Its hypertrophic scar if its raised, if its flush with the surrounding skin then its just a burned skin and i think it will take more a year or more to fade, u can use creams on it it doesn't matter, time is the best healer here.
