A classmate from grade school recently DM'd me, asking if I’d write a MediumBlonde post on how to create an effective anti-acne skincare routine for teens. And while MB is not a parenting blog, I figure most of us probably do (or will soon) have a teen or two in our lives (son, daughter, niece, nephew, grandchild, even a friend) who could use help combating acne without wrecking his or her skin.
