Nose and chin acne is mainly due to dietary factors, endocrine factors and abnormal keratinization of follicular sebaceous gland ducts, etc. It can be intervened by general treatment, medication and other treatments. 1. Dietary factors: In daily life, a diet high in sugar and fat can exacerbate sebum production and trigger acne. In this case, we should correct the above bad dietary habits in time and maintain a light diet; at the same time, we should strengthen personal hygiene management and avoid scratching the affected area directly with our hands. 2. Endocrine factors: Excessive secretion of androgens can lead to enlargement of sebaceous glands and increase in sebum secretion, triggering acne. For this situation, in addition to strengthening hygiene management, you can also follow the doctor’s instructions to apply spironolactone, compound cyproterone acetate and other drugs for treatment. 3. Abnormal keratinization of follicular sebaceous gland ducts: This can lead to narrowing or blockage of the sebaceous gland ducts, which in turn causes acne. For this symptom, intervention with oral isotretinoin capsules and fruit acid skin resurfacing treatment can be considered as appropriate. When acne symptoms appear, you should go to a regular skin hospital in time and follow the doctor’s instructions for the corresponding treatment.
