"i&#039;m 33 years old with bad forehead acne that started in my early/mid 20s. i&#039;ve been to dermatologists for years and everything i try eventually fails and seems to actually get worse in the long run. aczone has been awesome for me. it took about 3 weeks before it started working, but no side effects whatsoever. i&#039;m at about 2.5 months now and my skin hasn&#039;t been this good for many years. i love it. my skin isn&#039;t 100% perfect, but this is definitely the best thing i&#039;ve tried, and i&#039;ve tried a lot. right now, this is all i&#039;m using."
