"being 60 years old and still having acne, i&#039;ve been able to try lots of otc and prescription medicines for bad skin, from antibiotics to retin-a to a tons of other products.   aczone is the only thing that has actually worked.  i&#039;ve. been using it for over a year now and love it.  the product never made my skin worse like many products i have tried. it got better right away and has been clear now since i started using it."
