Acne is medically known as acne, and is usually caused by abnormal androgen levels, increased sebum secretion, abnormal keratinization of follicle openings, and infection with Propionibacterium acnes. 1. Abnormal androgen levels: irregular work and rest schedules and high stress levels can lead to increased androgen levels in the body and induce acne. 2. Increased sebum secretion and abnormal keratinization of follicle openings: If the patient has irregular eating habits, often eats fatty meats, chili peppers and other spicy and stimulating foods, or often stays up late at night, it is easy to lead to excessive sebum secretion, and abnormal keratinization of follicle openings can easily block the pores, making the patient’s face with acne on both sides of the jawbone. 3. Excessive proliferation of Propionibacterium acnes: If the facial skin is not cleaned properly, it is easy to lead to excessive proliferation of Propionibacterium acnes, which leads to local inflammatory reactions and induces acne. There are many reasons for acne on both sides of the jawbone, so it is recommended that acne sufferers take good care of their face and go to the hospital in time for diagnosis and treatment.
