999 Dermaplanin is actually a hormone, the main component of the drug is dexamethasone, which is actually a medium-acting glucocorticoid. For this drug, it is generally still widely used in the clinic, mostly mainly for inflammatory skin lesions, such as dermatitis, eczema, or contact dermatitis due to contact with allergens. However, because the drug is after all a purely hormonal topical drug, it should not be used for a long time if the patient’s skin has certain inflammatory damage. If used for a long time, it may cause localized hormone-dependent dermatitis or secondary infections such as fungal infections and bacterial infections.
