Is caffeine bad for the skin?

It seems like I'm getting fewer breakouts too, haha. Maybe it's just my imagination, though.

Is caffeine bad for the skin?

My skin has been breaking out even more lately because of my period, but I'm also wondering if it's because I've started drinking coffee again.

I'm curious about how caffeine affects the skin haha.
