Nose acne may be caused by folliculitis, acne, seborrheic dermatitis, mite dermatitis and other reasons. 1. Folliculitis: Nasal hair follicles are infected by bacteria, fungi and other pathogens, resulting in inflammation of the hair follicles, which may be localized in red pimples accompanied by itching, pain and other symptoms. 2. Acne: Acne is a chronic inflammatory skin disease of the sebaceous glands of the hair follicles. It is considered to be related to hormone levels and the proliferation of Propionibacterium acnes, which may lead to localized pimples, nodules and pustules. 3. Seborrheic dermatitis: Seborrheic dermatitis can occur in any seborrheic area, such as in the nose, may lead to localized erythema, papules, with itching. 4. Mite dermatitis: Mite dermatitis is usually associated with dermatitis caused by mite bites and contact with mite secretions. It is usually characterized by localized itching, edema, and pimples. It is recommended to pay attention to daily care, change the bad habits of life and diet, and go to the dermatology department of the hospital if necessary. Doctors will take into account the patient’s specific situation and formulate an appropriate treatment plan.
