If you changed your birth control, and you've been diligently using anti-acne skin care products for weeks, but you're still not seeing a reduction in chin acne, it's time to make an appointment with a dermatologist. "In the office I have topical prescriptions including Aczone, Retin-A, Tazorac and Onexton, which are all helpful in adult women," says Zeichner.

If you're pregnant and dealing with chin acne, you might feel stuck with it until you deliver — most anti-acne ingredients are off limits when you're expecting. But if you're willing to add a weekly dermatologist visit to your already full dance card of doctors' appointments, Ingleton recommends weekly blue light treatments. The LED kills acne-causing bacteria, and it's perfectly safe while you're pregnant.

If you've done it all, and you're still not seeing results, know that — like teenage acne — this too shall pass. Our hormones are constantly changing as we age, and our skin changes right along with them.
