Facial sores can be caused by bacterial infections, such as folliculitis or boils, which may be caused by Staphylococcus aureus. Most patients develop acne during puberty, and some middle-aged people may also develop sores on their faces. The reason for acne is that the increase in androgen levels causes the sebaceous glands to secrete a lot of sebum and increase sebum secretion, and the ducts that excrete sebum are overly keratinized and blocked. This results in an anaerobic environment. At this time, Propionibacterium acnes multiplication increases inside the hair follicle, which in turn causes an inflammatory reaction, resulting in edema, redness, swelling, and pus. If the inflammation affects the adjacent hair follicles and surrounding conditions, a hard nodule or lump will form on the face. Patients with sores and hard lumps on the face are advised not to squeeze them with their hands and need to visit a regular hospital where the doctor will prescribe anti-inflammatory drugs of the antibiotic type to subside them according to the situation.
