Pregnant women with perioral dermatitis should pay attention to the cleanliness of the face, avoid the use of glucocorticoid drugs on the face, and use medication for treatment if necessary. Perioral dermatitis is an inflammatory skin disease that occurs on the upper lip, chin, nasolabial folds, nose and other places. It may be related to long-term topical glucocorticoid use and excessive use of facial cosmetics. When a pregnant woman develops perioral dermatitis, she should first pay attention to facial cleanliness, use mild, non-irritating toiletries, and reduce the use of cosmetics. If there is long-term use of glucocorticoid drugs, should be discontinued or gradually reduced, the skin lesions can subside on their own. If necessary, you can use topical erythromycin, metronidazole, clindamycin and other drugs for treatment. The use of medication during pregnancy should be consulted in detail and used under the guidance of a doctor.
