make sure to follow every iota of directions/warning with it
if youre going to do it for any scarring be extra careful...I had a tiny ice pick scar I tried to get with the toothpick technique and because I burned off the stuff on the top..its a good sized scar now. Think of it like, the scar was vase shaped big at the bottom with a neck and small opening...I burned off the small opening and now its just a bowl. I knew it was a risk when I did it but it didn't make me any less bummed
the first time I did it I used 30% and my skin came out amazing...you HAVE to use a heavy moisturizer for a week after and your face will look like leather and you can NOT pick off the skin thats coming off in hunks
you MUST use sunscreen after (and should be anyway)
since then Ive only ever tried lower percentages because it hurts like you can't imagine and its never come out as good
do not get it anywhere near your eyes...srsly it will destroy your corneas
