what causes severe acne in adults
Acne in adult women is often hard to treat. One study showed that 80 percent of women prescribed antibiotics for acne receive no benefits from the drugs, Shinkai said. In these cases, the acne may stem from normal hormonal changes, such as those that occur around the menstrual cycle, or from a true hormonal disorder. For many of these women, medications that target hormones, rather than skin bacteria, would provide the most help, Shinkai said.
