I've had acne since 4th grade. Despite being told I'd "grow out of it", I still have it at age 23. I've tried what feels like every over-the-counter product available. I was doing moderately well using Neutrogena products when I decided to try Klear Action. After 3 weeks most of the blotchyness was gone. After 2 months I had about 2-5 pimples a month that came and WENT QUICKLY. At the 4 month mark I tried to be cheap and use AcneFree. Big Mistake. All my progress went bye-bye. I went back to Klear Action and am VERY pleased with the results. I can finally wear red or burgundy with out it bringing out redness in my face! I use it twice daily religiously and will not bother trying any other product. This truely works!
