I have been dealing with gross, dark acne scars in unpleasant places my whole life. i have tried everything. id soak my skin in vinegar DAILY, untill i learned about acid peels. I decided not to take any chances with it being too week, so on ebay i purchased a pack, two 1oz bottles, 50% and 70%, for only about 15-16 dollars free shipping(check out the seller, sharefair)
anyway, i went straight for the strongest stuff. i HAVE been over using it(full peels once every few days, and spot treating my scars with the 70) and yeah it gets pretty irritated when you do it so often.i actually burnt a hole in my belly(its oing away though) but if you follow directions(once a week, leave on for 2-6 minutes depending on tolerance) you shouldn't have any problems. so far im noticing my scars are definately a lot lighter, im not getting my usual pimply razor burn(im italian. i have to shave), im not getting new pimples, and my skin feels AMAZING. i am addicted!
do not let doctors fool you, they are after your $$. you can do acid peels by yourself no problem, for cheap! none of that silly $50+ per peel. you can get a whole 1 oz bottle for around 8 bucks on ebay, which is about 15 peels worth. just follow the instructions, if you need help elect a trusted friend. please don't waste your money needlessly! this works just as good! also, don't be fooled into buying a neutralizer. just mix some baking soda and water and pat it on if you really need it. wish you all luck in your quests for good skin!
and a side note, if you get one thats too strong, just dilute it with water! no need to go back and buy a weeker one. you'l get more for your money if you buy the 70 and dilute it. and do NOT use undiluted 70 on your face!
