Hmm, what also comes to my mind- and something i will try when i get a scar is this:
Get a ripe pineapple- cut it and save the skins. morning and evening rub on the scars- and let sit for about 10 minutes. Rinse then rub the scars with a cotton ball of raw unrefined apple cidar vinegar ( one brand sold is "Bragg's)
at night, cover the scars with raw honey and cover with bandages- the more raw the better.
Do this faithfully- even for over a month. Dont use any chemical commercial facial cleansers or creams.
