acne
"I got acne everywhere! Face, neck, back, chest and shoulders. Within the first 2 weeks my chest was completely clear, my face was a lot less bumpy (pimples not gone yet) and my blackheads dried out completely. I used pore strips to clear those out and no new blackheads appeared. 
As far as side effects, I got dry lips but Neosporin makes an overnight lip balm that really helps a lot. I use it during the day but really slather it on at night. My muscles feel weaker and I feel physically exhausted a lot faster with a slow recovery when I go to the gym. I've been on Claravis for 5 weeks now and I'd say the positive outweighs the negative for sure."
