I'm 21 and in college and I've been really getting into fitness for the past couple years but within the past year I started developing acne on my back when I never had before and I can't show off my progress with tank tops etc. without getting conscious about showing it.
I do not sweat much at all and when I do sweat I usually do the most from my face and not my back. I never wear the same shirt two days in a row and I do not wear super tight fitting clothing.
One thought I had was perhaps my towels were causing my back acne? I tend to use the same large towel to dry off after a shower for a few days or so, same with hand towels. Should I try changing towels more often (if that's even a possible factor)?
Are there certain foods I should avoid eating?
