My daughter a very bad break out a few months ago. It was to the point that she was too embarrassed to go to school, and started skipping out, I discovered, via calls from her school. It WAS bad, and covered her shoulders and chest as well as her face. We tried everything the drugstore had, but even the supposedly 'best' ones did very little. We were both feeling very disheartened when we finally got to trying this product. But then,within days, there was a noticeable improvement. My daughter did complain of skin dryness and flaking, but was ecstatic that the oxy was working! I purchased a moisturizing gel to help with her dryness and flaking, and between the two products she is nearly 100% acne free, and her skin looks great! Moms beware, however.. the peroxide will bleach your face cloths and towels, so designate one for the purpose!
