Acne is also known as acne vulgaris, which occurs around the mouth and nose. Acne is usually associated with an exuberant secretion of sex hormones during puberty, especially androgens, which can lead to an exuberant secretion of sebum, and if accompanied by the involvement of Propionibacterium acnes or abnormal ductal keratinization, it will form acne, resulting in the appearance of pimples underneath the nose and on top of the mouth.
In addition, staying up late, eating a spicy diet or living a stressful life and other factors can also cause acne under the nose and above the mouth and other skin problems, so you should try to maintain a good regular work and rest habits, quit smoking, quit drinking, and eat a light diet.
