After I started on Met and got AF again after 2 1/2 years of no period at all, I did notice some pimples about a week before AF came. I usually have very clear skin unless I'm stressed, (like the one monster pimple that showed up on my WEDDING DAY, grr.) It may have more to do with your hormones finally functioning correctly... I imagine it can sort of be like going through puberty again, now that you mention it. HTH!
