Acne, or acne, is the most common chronic inflammatory follicular sebaceous gland disease in dermatology, often occurring on the head and face, and may appear on both sides of the nose. It usually occurs due to endocrine disorders, excessive oil secretion, and bacterial infections caused by factors such as poor diet and late nights: 1. Endocrine disorders: Long-term mental stress, late nights, and unhealthy eating habits can easily lead to imbalances in human hormone levels and disruptions in hormone production and metabolism, which may lead to acne on both sides of the nose; 2. The action of androgens during puberty may lead to the appearance of excessive oil secretion. The sebaceous glands are highly functional, and oil cannot be discharged in a timely manner. A large amount of oil accumulates in the hair follicles, which may block the pores and cause acne on both sides of the nose; 3. Bacterial infection: Poor hygiene habits and other reasons lead to mite infections that block the pores, or bacterial infections that produce inflammatory reactions, resulting in acne on both sides of the nose. A variety of microorganisms in the hair follicles, especially the proliferation of Propionibacterium acnes, can induce or aggravate inflammation; 4. Other: excessive keratinization of the hair follicle opening, blocked ducts, which affects oil discharge, or excessive use of oily cosmetics, which aggravates the burden on the skin, can lead to the occurrence of acne. In addition, patients with polycystic ovary syndrome as well as Cushing’s syndrome may also have symptoms of acne on the lateral wall of the nose. The patient does not have to worry too much about the acne on both sides of the nose, it can disappear on its own after a period of time by regular and light diet, adjusting the work and rest, proper exercise and exercise, and proper use of cleaning products to keep the local skin clean.
