Dr. Shannon Heck is a dermatologist who sees many patients with acne. She says that while we don't know what causes acne, we do know that there are some factors that will make acne flare up. Genetics, stress and menstruation are a few of those factors.
Hormones are another factor. It's not unusual for women in their 40s and older to find themselves revisited with acne due to the re-shuffling of hormones for that age group. They may have the added bonus of hair beginning to sprout in undesirable places because of these hormone changes.
When these women come in to see Dr. Heck they are often surprised to be experiencing this relapse into pimples, along with the unexpected hair growth. Dr. Heck is not. She sees it all the time.
