Evidence Quotes

Highly Effective:

"I had such a bad breakout of large acne on my chest and face - unusual for me at 34. For a couple weeks, I always had a few pimple patches on at a time. After just a couple days of using this in the shower, I felt like it was getting noticeably better. Now after a week, it's all gone, and staying gone."

"My daughter has been through 2 rounds of Accutane and still has acne. She says this really works. Her trick is to let it sit on her skin for a couple minutes before ringing and then moisturize."

Requires Caution:

"This product is great for clearing up acne. However, I might have left it on too long or didn't rinse properly because the first time I used it I got a rash all over my face. Now I use a small amount in the shower and make sure I rinse it ALL off."

"This stuff is strong. Don't use it if you don't have a skin care routine! Also watch what you wear when you use it. It has peroxide in it and bleached a black shirt of mine."

Ineffective Cases:

"Been using for last few months this past year but NO change (does NOT work for people with dry sensitive skin) or it's simply just me."

Risk Factors:
