I was lucky enough to have clear skin in high school, so I never understood how awful acne really is. When I was 16, I received a Proactiv sample, liked how my skin felt, and continued to use it for years. Little did I know, hormones and acne go hand-in-hand. When I was about 21-22, 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. Proactiv did nothing. I tried every skin care line on the market for about 2-3 years, with no, or very little, results. I tried essential oils, raw honey, all natural soaps and salves, but nothing helped. I was so distressed, and frustrated. Finally, I found La Roche-Posays skin care products. Within 4 days, the inflammation decreased, the redness was fading, and my skin felt less dry. By 2 weeks, my skin was practically clear! I have been using this product for about 4 to 5 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. I get compliments on my skin regularly, and I feel confident not wearing makeup. Give this system a chance!
