"For me personally, my acne has taught me so much about self-confidence and loving yourself because it can be so mentally debilitating some days," Kathleen told POPSUGAR. "I've learned to just accept that my skin is not perfect and that's just fine! A majority of people don't have flawless skin, so I always try to remember that I'm not the only one. Being confident in my own skin ultimately comes down to accepting the fact that acne is a part of me, but I sure as hell don't let it run my life."
