I have always struggled with back acne really bad. I wash my back every single day, twice a day and I just can never get it to go away. Last year before prom my mom had the idea to try using Calamine lotion on my back acne (yes, the stuff you put on bug bites!) IT WAS THE BEST IDEA EVER! It is now before homecoming and I am doing It again. Not only did it dry everything up, it also helped get rid of tons of my acne scars from picking when I shouldn't have. Please try it if you need a remedy for acne!
