acne
"I have been using Epiduo for over 1 year now and besides the side effects, it has helped my face, chest and back acne tremendously!  For the first few months of using it, I had terrible dry, flakey and very red irritating skin. I didn't care as much then but it really became a problem when I began to wear foundation. I now know to moisturize  constantly and ONLY APPLY A THIN LAYER! 
Overall, thanks to Epiduo I barely have any acne on my chest. My back is no longer severely bad but now moderate and controlled. My moderate facial acne is so much better ! Only downfalls: sometimes my skin was terribly burnt and dry. Also really expensive but worth it!"
