I am 40 years and have recently been experiencing "40 year old acne" issues. I was having a new pimple pop up almost every day. I researched the net extensively and found a very thorough review of Zenmed products, comparing them to other acne products. So I decided to try it. I have been applying a small amount of the Derma Cleanse Acne Gel to my chin and neck in the areas I have been most prone to break outs each night before going to bed. Since using this product now for about 3 months, I have only had the occasional isolated breakout so I am thrilled with the results. I also was testing this product out on myself before my sons, who are approaching the age of teenage breakouts, would need to have a preventative acne product. I will definitely be purchasing the Acne Gel for them as well. I believe this might be the best product on the market!
