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.
