"i am 22 years i was given a sample of onexton from my dermatologist so i could get started until i got mine mailed to me. let me just say this stuff is amazing! my breakouts were significantly smaller and less noticeable with the first application. after a week my face was close to completely clear to where i just used it about twice a week. the reason i&#039;m giving it a 9 and not a 10 is because it did dry me out a bit but nothing you can&#039;t control with a good moisturizer. over all in love with this stuff."
