"i have been dealing with adult acne for years.  the product does work but i had to give it a little time.   it&#039;s been close to a month and my skin is almost clear.  i did have a few breakouts last week but were gone 2 days later.  i also experienced some dryness and peeling after washing my face with proactiv and applying onexton right after.  the other thing i noticed was unbearable  stomach and leg cramps the first day of my period.  i usually get cramps but 1 tylenol normally does the trick; not this time.  my cheeks are a little rosier than normal and my chin, which is where i apply most of the medicine, is turning a bit yellow (weird).  i think it&#039;s worth a shot but get in tune with your body in case there are any side effects"
