"I am a 23 year old female that has ALWAYS had problems with oily skin. A friend recommended this to me, and after reading the description I didn't really feel like this product applied to my issues, but out of an act of desperation I tried it anyway. I put it on once in the morning, once at night. It look a couple weeks to start really working, but it was like my face no longer knew what oil was. Even after a long tired day at work, or if I missed a couple days of using it, I still had no oil on my face! It didn't come back until I ran out and didn't use it for a couple weeks. The friend who recommended it to me only has to use it once a year to keep her skin under control. If you have an oily face, you need this!"
