Guangzhou Daily News (All-media reporter Ren Shanshan, correspondent Zheng Yinan, He Xupeng) Many people have had the experience of "fighting pox", and if they are not careful, they will "disfigure." Luo Diqing, chief physician of the Department of Dermatology of the East Hospital of the First Affiliated Hospital of Sun Yat-sen University, pointed out that it is necessary to clarify the root cause of acne and carry out four-level classification according to the nature of acne. More importantly, it is necessary to adhere to the daily four life management in order to effectively "reduce the burden" on the skin and finally succeed in "fighting acne".
How does pimples cause "disfigurement"?
Chief physician Luo Diqing pointed out that most people have acne has a genetic background, under the action of genetic factors, the hair follicle mouth epithelial keratosis is excessive, blocking the hair follicle opening, resulting in the secretion in the hair follicle can not come out, the formation of visible acne, of which, the acne without opening is called "whitehead acne", if the surface of the acne opening is oxidized by air, it will form a "blackhead acne".
Dr. Zhao Yukun of the Department of Dermatology of the East Hospital of Zhongshan First Hospital pointed out that some people's hair follicles are blocked because of the strong secretion of sebaceous glands. The most direct cause of excessive sebaceous gland secretion is excessive androgen secretion, increased androgen activity, there are its own endocrine diseases, such as polycystic ovary syndrome, there are also factors of life and rest eating habits, such as with the increase of life pressure, the pace of life accelerates, many people often stay up late, in a state of mental tension, anxiety, like to eat spicy fried, greasy, high-sugar food, and even consume too much milk.
Skin inflammation caused by blockage of the hair follicle mouth and the formation of cysts will lead to liquefaction and degeneration of the dermis, excessive repair will form hypertrophic scars, and insufficient repair will lead to acne pits, resulting in local "disfigurement".
Can't squeeze acne? not necessarily
After the outbreak of acne, many people habitually squeeze the acne, and some people emphasize that "you can't squeeze the acne". Chief Physician Luo Diqing pointed out that if it is a mature pustule or a shallow acne that has been opened, it can be gently squeezed under the premise of disinfecting the skin of the hand and the affected area. However, it should be emphasized that after squeezing, fusidic acid cream or azelaic acid and benzoyl peroxide should be applied topically for anti-inflammatory and antibacterial treatment.
For deep acne and inflamed acne, do not force squeeze, so as not to damage the dermal fibers and the basal layer of the epidermis, resulting in acne pits.
Battle "pox" to be graded Drugs to be selected
Zhao Yukun stressed that acne is divided into four levels, and should be "prepared" according to the grading of acne:
Grade I. (mild): sporadic or multiple acne, with scattered inflammatory papules, mainly external medication treatment, can be combined with red and blue light, chemical peeling is commonly known as "brush acid".
Secondary II. degree (moderate): oral antibiotics are added.
Grade III( severe): oral tretinoin therapy and photodynamic therapy.
Grade IV. iv(polymerization): therapy with hormone suppression of immuno-inflammatory and antiandrogenic activity.
It is particularly reminded that acne around the mouth and chin and neck, most of which occur in postpubertal people or people with endocrine disorders, is resistant to conventional antibiotic treatment and will use some anti-androgenic activity treatment options.
Life management reduces the occurrence of acne
Chief Physician Luo Diqing suggested that four life management should be done to reduce the burden on the skin and prevent acne from the source.
One is less fat, less sugar, less spicy, less dairy products on the diet; the second is not to stay up late, moderate exercise; the third is to try not to use, less use of foundation, makeup, if you must wear makeup, you must remove makeup in time and thoroughly; the fourth is sunscreen, because ultraviolet rays will stimulate the secretion of sebaceous glands, and lead to the accumulation of keratin in the hair follicles.
Depending on each person's skin condition, the anti-acne strategy can be refined like this:
1. Oily and acne type: gentle cleaning, careful choice of skin care products. Patients present with both sebaceous gland secretion and excessive keratosis of the hair follicle mouth and hair follicle catheter, and daily care should be done to clean and control oil.
Cleansing Choose a mild cleanser with amino acids, do not choose those that contain soap bases, otherwise it will destroy the sebaceous film and cause skin sensitivity.
Essence and lotion can choose refreshing and balanced oils, such as vitamin B3, plant (cucumber extract, tea tree extract, witch hazel extract, etc.), you can also choose products containing salicylic acid, fruit acid to control oil and dissolve horn plugs, or products containing antibacterial peptides and azelaic acid ingredients antibacterial and anti-inflammatory.
2. More oil and less acne type: oil control and hydration. Daily to do a good job of moisturizing the skin, fundamentally control the oil.
3. Less oil and more acne type: remove keratin, moisturize brush acid. This type is manifested as more hair follicle or corner plugs, should do a good job of removing the care of keratin accumulation, usually pay attention to moisturizing, you can use some products containing fruit acid.
