Acne is mainly related to androgen levels, mostly in young men and women. Due to strong androgen secretion, sebaceous glands secrete a large amount of oil and clog pores, causing acne.

2. Abnormal keratinization of cells around hair

follicles leads to small hair follicles, oil secretion does not come out, acne will form secondary acne.

3. Excessive proliferation of Propionibacterium acnes

Due to excessive proliferation of Propionibacterium acnes, Propionibacterium acnes will hydrolyze triglyceride in sebum to stimulate inflammation around hair follicles or hair follicles, resulting in local papules, pustules, nodules and abscesses.
