acne
"Okay I just switched from using Differen which helped my skin but didn't completely cure it. I have always had mild to moderate acne. I went to my dermatologist and  I started using Retin-A every other night for the past weeks and few days. I'M BREAKING OUT LIKE THERE'S NO TOMORROW. This is awful and I have to go to school during this. I really hope this is just the initial breakout, and I'm not one of the people who end up saying this left my skin worse then when I started. I'm going to give it another month or two."
