That is at least one thing MTF don't have to worry about! LOL. Skin actually gets much better and healthier on E and T-blockers. I had horrible acne as a teen and it persisted pretty much until I decided to start HRT, and then it was all gone. Ok, I'll stop rubbing it in.
You'll probably have to add "Proactive" or the like to your transition regimen. Sorry. Welcome to male puberty.
