This is my second time buying this glycolic acid peel from Skin Obsession. I've never had any issues or problems using it. I use it every 2-3 weeks and leave the acid on for 5 minutes (timed) and wash off with baking soda mixed with cool water. Then I apply a thick layer of face lotion. The next day my skin feels very smooth. I find that it helps active acne dry up and fades old acne red spots. My skin complexion has definitely improved since I started using this product. Also, the free microdermabrasion crystals they throw in with the purchase are amazing! Obviously this peel isn't going to be as good as one you'd get from a professional - they put a numbing agent in the peel so its not painful and can be left on longer. You're not going to experience actually peeling of your skin from this product. But around here a chemical peel is about $300 so I'm going to stick with this cheaper option!
