"Hey, doctor, save my face." Recently, Xiao Wang, a girl in her 20s in Hangzhou, went to the dermatology department of Zhejiang Provincial People's Hospital with a red and swollen face.
The department received nearly 100 cases of contact dermatitis of varying degrees caused by improper brushing of acid in one year, mainly after 90 and 00.

Xiao Wang told the doctor that he listened to a "beauty blogger" recommendation, shopped 30% of the high concentration of fruit acid online, and brushed acid at home with the video of a beauty blogger on the Internet, resulting in hot redness, scabs, redness and swelling on the face, and could not see people.
Xiao Wang said that 30% of the high concentration of fruit acid just felt a burning sensation on the face, followed by a flushed face, red cheeks and white cheeks. The next day, the face began to scab. Consciously the problem is more serious, Xiao Wang quickly sought medical treatment.
"This is the 'contact dermatitis' caused by brush acid stimulation, 30% of the fruit acid has reached the concentration of medical brush acid, there is a strong peeling, corrosive and irritating, resulting in Xiao Wang's facial redness, scabs." Although it will improve after treatment, there is still a risk of leaving pigmentation and skin sensitivity. Tao Xiaohua, director of the Department of Dermatology of Zhejiang Provincial People's Hospital, said.
Tao Xiaohua introduced that the so-called "brush acid" is a chemical peel, also known as chemical peeling, which is to apply chemical preparations to the surface of the skin, resulting in controllable damage to the skin to promote new skin regeneration. The type of chemical agent, its concentration, and the duration of its stay on the skin can all affect the depth of the peel. According to the different depths of action of chemical skin resurfacing, it can be divided into shallow skin resurfacing, intermediate skin resurfacing, and deep skin resurfacing. The deeper the skin resurfacing effect, the more pronounced the effect, and the greater the chance of adverse reactions.
"Problems like acne, closed-mouth pimples, etc., acids can be used appropriately. But 'applying acid' and 'brushing acid' are not a concept. This year, the State Food and Drug Administration specially issued a document on popular science, the use of acid-containing ingredients of skin care products called acid, at home can be moderately coated acid; medical concentration of acid, such as more than 20% of the fruit acid, 30% of salicylic acid brush acid, brush acid is a medical behavior, must be carried out in the hospital. Tao Xiaohua said that when carrying out "brush acid" treatment in medical institutions, professionals will choose the appropriate concentration and program according to the actual situation of the patient, and can scientifically observe and judge the reaction process of the skin in the treatment, and give intervention or timely termination when necessary, "Like Xiao Wang, using high-concentration medical acid products at home is absolutely not recommended."
