Try using a topical anitseptic, I'm currently using one and I've definely seen an improvement in the acne on my back and shoulders, that damn test does it to me every time!!! Go to your local pharm and ask for Hibclens, apply after showering with cotton guaz pads, let dry and then either let it on or wipe the areas with wetted cotton balls. This definetly worked for me. Also, see if you can get any sort of antibiotics, they will help the situation. One more thing shower with a lufa and anitbacterial soap. Good luck!
