Ms. Zhao accidentally used a kind of cosmetic, and subsequently, her skin became itchy. In order to relieve the itching, she used another kind of ointment. What she did not expect was that after more than two years, not only had the itching not been cured, but unsightly "black beard" also appeared on her chin. Recently, Ms. Zhao went to the hospital for treatment, and the doctor diagnosed her with "hormone-dependent dermatitis".
