i've been using the retin-a .1 on my forehead every night for almost two weeks. i think it's going fine, and i know it will take longer to see full results. i would like to use it on the rest of my face if it works well on my forehead. the past couple of weeks i've been getting a few more pimples than usual around my mouth/cheeks...could be my period? a couple have left red marks for longer than i'm used to, but they're fading. i also have been using pur minerals (as opposed to my normal bare minerals) for the last 3 days, so i'm hoping that isn't a problem because i like it so far!
