I. What is “acne”?
“Acne is a chronic inflammatory disease of the sebaceous glands of the hair follicles, commonly seen in dermatology. It occurs in adolescence. Its onset is related to the imbalance of sex hormone levels in the body, excessive sebum secretion, microbial infection, abnormal keratinization of hair follicle sebaceous glands, as well as immune and genetic factors. According to statistics, 80-90% of people have suffered from “acne”, after puberty, the symptoms are often reduced or self-healing.
Why does “acne” occur in adolescence?
With the development of the human body, the gonads in the body gradually mature, and the sex hormones in the body are often maintained at a high level during puberty. The actual fact is that androgens are a key factor in the pathogenesis of “acne”, and research shows that androgens can regulate the differentiation and growth of sebaceous glands, which can stimulate sebum secretion from sebaceous glands. Therefore, “acne” is mostly seen in adolescence.
Third, what is the specific pathogenesis of acne?
Acne is the result of a combination of pathogenic factors. The face, chest and back, and scapular area are areas where sebaceous glands are densely distributed. The abnormal stimulation of androgens and other factors often leads to excessive sebum production. Studies have found that the sebaceous ducts of hair follicles in acne patients are often hyperkeratotic, narrow or obstructed, resulting in sebum and hair follicle shedding cells not being able to drain smoothly, resulting in “pimples” or “acne”. Propionibacterium acnes and oval spores of furfur can break down sebum and produce free fatty acids, which in turn stimulate non-specific inflammation in the hair follicle and its surrounding tissues.
What are the manifestations of “acne”?
The most common type of acne is the common acne, which appears on the face, chest and back, and scapular area as follicular papules with yellowish-white or grayish-brown tops, and squeezed lipid plugs (acne). In severe cases, bean-sized pustules or dark red nodules or cysts may appear (Figure A). In addition to the common type, more severe cases of acne aggregatica (Figure B), acne fulminans (Figure C), purulent sweat glands (Figure D), and perifolliculitis (Figure E) can also be seen clinically.
V. How to treat acne?

4.Light therapy such as red light, blue light therapy, etc.
The treatment of “acne” can not be “eradicated”, can not be treated?
The main clinical manifestation of “acne” is acne, inflammatory papules, pustules and abscesses, which often leave more obvious scarring, scars or pigmentation during the course of the disease, so you should actively seek medical attention.
