Sweat patches, also known as florid chafing, are superficial skin infections caused by Malassezia, and are treated with general therapy, topical medications such as ketoconazole cream, and oral antifungal medications. Malassezia furfur is a superficial infection caused by Malassezia violating the stratum corneum of the skin, which often manifests itself as a pore-centered punctate, round, or oval rash, which can later increase in size and merge, and is covered with furfuraceous scales. The general treatment of pityriasis versicolor includes frequent bathing, changing clothes, and keeping the skin clean and dry. The general treatment of florid chaff rash is mainly with topical antifungal drugs, such as 2% ketoconazole lotion, 2.5% selenium disulfide lotion, as well as bifonazole cream, ketoconazole cream, miconazole cream and so on. You can wash with the lotion before applying the cream or ointment. Antifungal medications such as itraconazole can also be taken orally if the lesions are large or recurring. All of the above medications should be used under doctor’s supervision to minimize the occurrence of adverse reactions in children after use. If there is any discomfort, it is recommended to consult a doctor promptly.
