Acne, or acne vulgaris, may be related to high androgen levels, clogged follicle pores, and infections. 1. High androgen levels: After puberty, the level of androgen in the body may be too high, leading to an increase in sebum secretion, and the shedding of dead skin cells as well as oil may clog the pores, making it easy to form acne. 2. Follicular pore blockage: Due to the large number of pores in the eyebrow area, if you don’t pay attention to daily care, the abnormal keratinization of the cells around the follicular pore can lead to the follicular opening becoming smaller, narrower and blocked, and the sebum can’t be discharged normally, which will lead to the formation of acne easily. 3. Infection factors: such as frequent eyebrow tattooing or eyebrow area has been damaged, the hair follicles are damaged, which will easily lead to the propagation of Propionibacterium acnes, causing inflammation, which will cause acne above the eyebrow. It is recommended to go to the dermatology department of the hospital for appropriate examination to identify the specific causes and carry out targeted treatment.
