Sweaty skin is medically known as eruption, which can be treated by general care and medication. 1. General care: Eczema occurs in warm, moist folds, so patients need to keep the affected skin cool, pay attention to local ventilation; keep the living environment at a suitable temperature; wear wide, moisture-wicking clothes. 2. Medication: glycerite lotion can be used, which can stop itching, and keep the affected area dry with powder after cleaning; for those with local infection, antibiotic ointment can be used, such as erythromycin ointment, mupirocin ointment, and so on. If the patient has a need for medication, it must be carried out under the guidance of a professional physician, and must not be applied blindly, so as not to lead to adverse consequences.
