Acne, commonly known as pimples, acne vulgaris and acne vulgaris, is a common chronic skin disease. According to authoritative statistics, 95% of males and 85% of females suffer from acne to varying degrees during puberty, so it is aptly called “pimples”. The causes of acne are complex, but in general, the follicle-sebaceous gland unit of the skin changes under the action of various factors. What is the follicle-sebaceous gland unit? Hair follicles open on the surface of the skin, hair growth in the follicles, sebaceous glands through the sebaceous ducts connected to the follicles and sebum into the follicles, and then through the mouth of the follicles will be transported to the surface of the skin sebum in the surface of the formation of the “oil film”, the oil film on the skin has a certain role in the protection. In fact, the hair follicle is a pipeline system, dirt produced, through the first level of the pipeline, and ultimately discharged, but if the pipeline is clogged in any place, or dirt discharge too fast, more than the pipeline’s discharge limit, will lead to the accumulation of dirt, and problems. In the same way, if the follicle opening or sebaceous gland duct is clogged, or if the sebaceous gland produces too much sebum, causing sebum to accumulate in the follicle opening or sebaceous gland duct, black or white head acne will form. At the same time, the accumulated sebum becomes the culture medium for bacteria to grow, and the bacteria will multiply and cause localized inflammation of the hair follicles. When the inflammation is mild, it appears as red, inflamed pimples; when it is severe, it may appear as more serious nodules or cystic acne. Does acne happen to everyone? The chances of developing acne are high, and studies have shown that 80-90% of adolescents have suffered from acne. This is closely related to the significant changes in body development and hormone levels during puberty. Acne not only occurs in adolescents, foreign research shows that the incidence rate of people over 20 years of age are: 20-29 years old, male 42.5%, female 50.9%; 30-39 years old, male 20.1%, female 35.2%; 40-49 years old, male 12.0%, female 26.3%; 50 years of age and older, male 7.3%, female 15.3%. It can be seen that acne has a higher incidence not only during puberty, but also after puberty. Therefore, do not make the mistake of thinking that acne only develops during puberty and that it will subside after puberty and leave it untreated, delaying the condition. According to the different infections, different problems, acne is divided into several categories: 1, punctate acne blackheads pimples is the main damage of acne (pimples), is stuffed in the follicle sebaceous gland mouth of the cheese-like semi-solid, exposed in the follicle mouth of the outer end of the black, such as the pressure to squeeze, visible head is black and the body of the yellowish-white semi-transparent sebaceous plugs are discharged. 2, papular acne lesions to inflammatory pimples, mainly millet to pea-sized hard pimples, light red to dark red. In the center of the papule, there may be a blackhead or an undarkened sebaceous plug at the tip. 3, pustular acne to pustular manifestations of the main, pustules for grain to mung bean size, for follicular pustules and papules at the top of the formation of pustules, broken pus is more viscous, after the healing of the left shallow scar. 4, nodular acne when the inflammation site is deeper, pustular acne can develop into thick-walled nodules, varying in size, light red or purplish red. Some are deeper in location and have significant elevation while in a hemispherical or conical shape. They can be long-lasting or gradually absorbed, and some abscess and ulcerate to form significant scarring. 5, atrophic acne papules or pustular damage destroys the glands, causing pit-like atrophic scarring. The ulcerated pustules or naturally absorbed papules and pustules can cause fibrous changes and atrophy. 6.Cystic acne forms sebaceous cysts of varying sizes, often secondary to suppurative infections, and often exudes blood-tinged jelly-like pus after rupture, while inflammation is often not serious, and later forms sinus tracts and scarring. 7, polymerization of acne is the most serious kind of damage, lesions polymorphic, there are a lot of pimples, papules, pustules, pustules, cysts, and sinus tracts, keloid scars, keloid scars occur in clusters. 8, malignant acne damage for millet to broad bean size greenish red or purple-red papules, pustules or nodules, light and soft, and contains pus and blood, they do not heal for a long time, and later healed leaving tiny scar, and do not feel pain, infiltration is also very little. Different parts of acne are manifestations of physical problems: 1. Nose: Acne on the nose is related to fire. People who eat a lot of fried, fatty foods and have an innate hot body will get acne on their nose. 2, cheeks: pimples on the cheeks may be due to bad moods, late nights and other reasons. Because emotional management directly affects the liver and gallbladder, liver and gallbladder meridians through the cheeks, emotional anxiety, nervousness before menstruation will cause liver qi stagnation. 3, forehead: forehead acne may be caused by endocrine disorders. For example: irregular menstruation, eating supplements containing hormones. In addition, there are breast lumps, uterine fibroids, hormone levels were abnormal, eat more soy foods will cause hormone levels rise, easy acne. 4, chin: chin acne is mostly caused by eating spicy, fatty foods. Because the human body’s digestive system of gastrointestinal meridians mapped on the skin of the chin, gastrointestinal discomfort, the chin has a performance. Acne is mainly caused by endocrine factors in the body, followed by the skin not being thoroughly cleansed. There are also other causes such as diet and psychological factors. Acne skin care precautions: 1. Avoid steaming your face, and don’t use a hot towel on your face or put ice on your acne. All these behaviors will lead to a rapid change in temperature, which can easily cause skin inflammation and is not conducive to the fading of acne. 2, usually eat more fruits and vegetables, supplemental vitamins, you can take oral vitamin B6 + vitamin A. Vitamin B6 orally helps to modulate the function of the sebaceous glands; vitamin A has the role of inhibiting keratinization of hair follicles and the generation of lipid peroxides. 3, acne patients generally have follicle sebaceous gland duct keratinocyte hyperplasia phenomenon, hyperplasia keratinocytes blocked the duct, another sebum can not be discharged, the formation of pimples. Doing a good job of facial cleansing can reduce the occurrence of ductal blockage. 4, acne patients must pay attention to sun protection, avoid sun exposure to cause inflammation of the skin lesion area of hyperpigmentation. 5, moisturizing is a major problem for acne skin. Because after cleansing the skin surface lipid reduction, sebaceous glands in the negative feedback will secrete more oil, will be another already blocked follicle sebaceous glands to form pimples, or aggravate the lesions. So after cleansing must pay attention to hydration and moisturizing, to maintain the balance of oil and water. 6, away from cigarettes, a lot of smoking will make the oil secretion exuberant. 7, avoid staying up late, the best skin metabolism toxin time is 10:00 p.m. – 1:00 p.m., so it is important to rest before 10:00 p.m..
