There is a foul odor on both sides of the nose when rubbed, which may be the odor that appears after the oily glands on both sides of the nasolabial folds secrete products that accumulate and are broken down by bacteria. Follicular sebaceous glands are regulated by sex hormones and are independent endocrine tissues of the skin. An imbalance of estrogen and androgen levels in the body or elevated levels of androgens can increase the secretion of sebaceous glands. Without timely attention to facial skin hygiene and cleanliness, the oil secreted on both sides of the nasolabial folds is broken down by bacteria, and the sebaceous secretions with odor can be discharged by rubbing or squeezing both sides of the nose. At this time, if there are sebum, keratin plugs and other substances accumulated in the follicle mouth around the nose, can form folliculitis. Usually pay attention to keep the local skin clean, eat less spicy and stimulating food. If there is an increase in sebum or pimples on the skin, it is necessary to consult a doctor, who will provide targeted treatment according to the symptoms of skin damage.
