Why Do Adults Still Get Acne?
Why do adults still get acne? Up to 50% of women in their twenties experience it — and it has nothing to do with dirty skin. In this episode of So That's Why, Jen (PhD in biochemistry and molecular biology), Chris (formulation scientist with 30+ years of experience), and Matt unpack the four biological processes behind every breakout and explain why they keep being triggered throughout adult life. They dig into the specific adult drivers — hormonal shifts, cortisol, and the blood sugar pathway — bust the persistent myths around pore size and hygiene, and cover what the evidence says about treatment, including the timeline that most people get badly wrong. Whether you've been dealing with adult acne for years or suddenly started breaking out again, this episode explains the actual biology at play.
