Re: Acne on chest/back...31 years old...help!
Hello missouri, I used to have the same problem as you.
I found that putting foundation on my back dries them up, and they tend to go away in a few days. I know it sounds strange, but it has worked a charm on me for years. Of course you cannot use oily foundations. (Id avoid l'oreal as it's more oily, along with brands that are not well known)
I use it from the company maybelline, it takes a few days but as the days go by you can notice that they are going down. maybelline is also the best product in regards to foundation as it is safer then competitors.
It's worth a shot if anything, best of luck!
