Acne vulgaris occurs in young people. They appear as red “pimples” on the face, chest, and back, and can have white heads. Some “pimples” are the color of skin and are the size of a pinpoint, so they are called acne. In terms of differentiation, facial eczema can also occur as patches of small bumps. Eczema is very itchy and can be severe enough to cause water to run. Some people with acne also itch, but most people have pain or no sensation. For the treatment of acne, for less severe lesions, “red bumps with white heads” can be treated with topical Listerine and Bansal; for pinpoint-sized bumps of skin color, topical Darvon can be used. For patients with more pronounced inflammation and more lesions, oral minocycline can be used in addition to the above topical medications. For cystic acne, or cystic alopecia folliculitis that leads to hair loss, Tylenol can be used under medical supervision. Oily skin, irregular menstruation, dry stools, staying up late, and emotional stress and depression can easily trigger acne. Patients with oily skin should pay attention to washing their faces with warm water when they have a lot of oil. Female patients with irregular menstruation should go to the obstetrics and gynecology department to regulate their menstruation. Everyone should pay attention to a light diet and eat less chili, greasy and sweet foods. Keep your bowels open. Do not stay up late and be in a calm mood.
