The appearance of acne in this part of the face at the edges of the contour depends on the situation, and generally two conditions can cause patients to exhibit acne in this area. The first is common acne. Patients will not only have acne in these locations on the face, but also on the edges of the face, which is a common chronic inflammatory reaction in the hair follicle area. However, there are also patients who do not have visible acne on their face, or who have visible acne on their face, but there is a clear difference between acne on the face and the appearance of these acne manifestations on the edges of the face. Malassezia folliculitis is caused by Malassezia, which is a fungal infection. The patient is often not able to identify it carefully at home, and must go to the dermatology department of a regular hospital for this condition.
