It's also surprisingly gentle enough to use twice a day, meaning you'll be able to attack acne in the AM *and* the PM without making your complexion overly dry.
Promising review: "I was lucky enough to have clear skin in high school so I never understood how awful acne really is. When I was about 21-22 years old, I switched to a birth control implant, and that thing wreaked havoc on my entire life. I suddenly had horrible cystic acne. Not only did it make me self conscious and uncomfortable, but it was actually so painful — laying on my pillow hurt my face! To top it all off, my skin was also dry, and irritated. I tried every skin care line on the market for about two to three years, with no, or very little, results. Finally, I found La Roche-Posays skincare products. Within four days, the inflammation decreased, the redness was fading, and my skin felt less dry. By two weeks, my skin was practically clear! I have been using this product for about four to five years now, and I haven't had a single outbreak, EXCEPT for the time I wanted to try a different product to save money. Huge mistake, one I will not make again." —LadyHawke
