What causes pimples around the mouth and chin

Acne around the mouth and chin, generally referred to as pimples, acne, belongs to the follicle sebaceous gland area of the chronic inflammatory disease, the main causes include heredity, follicle sebaceous gland duct keratinization abnormalities, Propionibacterium acnes infections, and androgen level abnormalities and so on.
1. Heredity: Acne has a certain hereditary tendency. If parents suffer from acne, the possibility of their offspring developing acne will also increase.
2. Abnormal keratinization of the sebaceous gland ducts of hair follicles: This can cause the sebaceous gland ducts to become narrower and smaller, resulting in sebum not being able to be discharged in time and accumulating in the follicle opening, forming pimples and acne.
3. Propionibacterium acnes infection: also known as Acinetobacter, which is mainly found in the hair follicles and sebaceous glands of the skin, the overgrowth of Propionibacterium acnes will also aggravate the phenomenon of acne and pimples.
4. Abnormal androgen levels: Increased androgen levels in the body after puberty promote enlarged sebaceous glands and increased sebum secretion, which clogs pores with oil and shedding dead skin cells, thus forming acne and pimples.
It is recommended that patients with acne around the mouth and chin go to the hospital in a timely manner, under the guidance of the doctor to standardize the treatment, do not blindly use their own medication.
