Here we will first talk about acne. For example, most people who grow on their backs are called folliculitis, and the pathogenesis of folliculitis and acne. First, the sebaceous gland secretion is relatively strong. Because of the secretion of hormone levels in adolescence, the secretion of sebaceous glands is relatively strong, and then the hair follicles become keratinized. After keratinization, sebaceous glands cannot be secreted. Secondary bacterial infections often lead to propionibacterium infection. But it is easy to combine fungal infection in the chest and back, such as Pityrosporum furfur. If Pityrosporum furfur is combined, antifungal drugs may be added, such as oral itraconazole, some may use physical therapy or red blue light, and some may also use ointment, such as anti-inflammatory ointment, such as benzoyl peroxide, and fungal ointment, such as ketoconazole.
