I've had peels at spas and dermatologist offices. One time they burned my facade left me a huge dark mark at a spa.... And this is the same stuff they use. Would you rather spend 150 per peel or just DIY it yourself? Depends on how good you are at following directions I guess. Be very careful to not leave it on too long or you really can burn your face! Not good for anyone. I've done it once so far leaving for 30 seconds and already brown marks have faded slightly.. Can't wait to see the difference after a few more. I did some research on websites about doing at home peels and there's some good info to help,out there, my best advice is to BE PREPARED! I had a cold baking soda mix on hand along with a cold chamomile tea to nourish my skin after and it worked out perfectly. Good luck!! :)
