Introduction
Introduction Acne is divided into whitehead acne and blackhead acne, whitehead acne we call it closed acne, closed acne is more difficult to cure in clinical cure. Whitehead acne occurs because the stratum corneum is too thick, and whitehead acne is an unstable acne (closed type) that easily evolves into a blister. 1. The basic damage is follicular papules, surrounded by red color, squeezed with rice-like white fat plugs, and no blackheads, grayish white papules, called whiteheads. If inflammation occurs, the acne is red and small pustules appear on the top, which can affect the appearance. After rupture and healing, there may be temporary pigmentation or mild depression, and some forms of nodules, abscesses, cysts and scars, etc., and even multiple sinus and scars after rupture, severe cases It has an orange peel face. Clinically, one or two kinds of damage are often obvious. At the same time, there is oily sebum overflow and facial and seborrheic dermatitis. At this time, the face is greasy and shiny, and erythema can also occur, and oily suede is covered. Not healed. 2. The incidence of the population is mainly 15-30 years old, because the degree of acne naturally decreases with the decline of skin oil. As you get older, the skin slowly turns from oil to dry, which is why the older the less acne. The location of the disease is more than the face, but also in the upper part of the chest and back and shoulders, chest, neck, buttocks and so on. Consciously it may be slightly itchy or painful, and the course of the disease is lingering, often one after another, new rashes continue to be secondary, and some may be extended for several years or more than ten years. 3. The problem of polymerized acne is long, and it is common in men. Common pimples, nodules, cysts, abscesses, sinuses, scars and other damages are mixed together. This acne is widely distributed. 4.85% are mild acne patients, acne is mild acne, small volume is small, such as good care, acne will not last for a long time, after the inflammation subsides, generally no scars and other sequelae. 10% are moderate acne patients, acne patients are moderate acne, large in volume, easy to form abscesses, so that pus at the top of acne, after micro-touch pain, such as good care, etc., after the infection subsides, generally will not stay Lower scar. 2 to 3% is a high-level acne, acne patients are heavy acne, large in volume, wide in distribution, long-lasting disease, severe tenderness, such as poor care, it is easy to leave scars, pits and other sequelae.

Androgen can directly stimulate the increase of sebaceous glands, promote the keratinization of hair follicles, block the pores and cause inflammation, causing acne and acne.
2. Related to the female physiological cycle: some women exacerbate the blister before the onset of menstruation. Mainly related to changes in hormone secretion.
