Ahhh! The dreaded acne. As teenagers, this is something to be expected perhaps. Still, it is an unwelcomed house guest that we can't wait to see go! Maybe you are in your 20s and are noticing these blemishes appear on your skin overnight. 30s and still seeing problems along with a change of hormones and overwhelming stress. And 40s! What?!?! Say that it can't be true that you can get acne in your 40s.
