I'm nearly 37 years old & have been experiencing those stupid pimple problems most of my life. My face isn't really a problem anymore. But now it's my neck & chest, upper back. My acne isn't bad enough for accutane, it comes & it goes. It seems that now it's prone to breaking out AFTER my period is gone. I've been using Oxy 10 & was wondering, is it possible that it will stop working after a while. Has anyone gone WITHOUT using all these acne medicines & found that their skin goes back to normal?
