I'm over 30 and I have acne only on my jaw line what can I do for it and could my husbands whiskers irritate and cause acne?

Hormonal likely. Typically, when I see a woman over 25 with tender, long-lasting deep cysts around the jaw, it is hormonal. There is a medication called spironolactone that works well as an rx after some blood tests. The blood tests are usually normal but your skin can bee too sensitive causing the acne. I also recommend organic foods free from hormones and avoiding foods high in sugar (high glycemic).
Proactiv. If it is mild that will work for you. Irritation can definitely lead to acne. Treatment can be retinoids, chemical peels, antibiotics, laser and ipl treatments.
