After that, Ms. Jin went to the beauty salon every two weeks to "brush the acid". Later, because I was busy at work, I bought related products online and brushed low-concentration "acid" at home. In her view, although "brush acid" has never been disfigured, "brush acid" is indeed exaggerated or not positively recognized. "I think there is indeed an exaggeration, saying what will happen after brushing, but it actually takes a certain amount of time, and it is impossible to do it immediately after brushing." Ms. Yu said.
In the information released by the State Administration of Medical Supplies, it is suggested that "brush acid" may cause adverse reactions. Higher concentration of "acid" will irritate and destroy the skin to some extent. With the increase of "acid" concentration and the extension of residence time, the probability of adverse reactions will also increase.
The so-called "brush acid" is actually a chemical "skin rejuvenation" technology. The deeper the effect of "skin changing", the more obvious the effect and the greater the probability of adverse reactions. Temporary erythema, swelling, tingling, burning pain and other discomfort may occur during the treatment, and scabbing and pigmentation may occur after the operation. In addition, there are rare burns, erosion, abnormal pigment, miliary papules, scars and so on.
Yan Yan said that "brush acid" is a formal medical behavior and belongs to the treatment category of medical beauty. From its scientific principle, it is a controllable injury to the skin. Therefore, not everyone can operate. "This is a kind of injury, but this kind of injury is controllable. It plays a therapeutic role by accelerating skin metabolism. However, in the process of' brush acid', it is not the same for everyone to adjust the concentration of' acid', the residence time and the intensity used by doctors according to the patient's condition. The stop time is controlled by the doctor. If it is not well controlled, it will cause harm if it is not stopped in time. "
The popular science article published by the State Administration of Medical Supplies specifically mentioned that "brush acid treatment" needs to be operated by trained professionals in hospitals or clinics with medical qualifications, and the "acid" used is not cosmetics. At present, there are many kinds of "acids" used in "brush acid treatment", and some "acids" cannot be used in cosmetics.
Some "acids", such as acid and salicylic acid, can be added to cosmetics, but there are strict use restrictions and technical requirements. For example, the content of salicylic acid in cosmetics should not exceed 3%. Yan Yan said: "The brush acid we are talking about is actually the brush acid in the medical sense. It doesn't mean that applying acidic skin care products at home is called' brush acid', so' brush acid' must be done in the hospital. The concentration of' acid' in household skin care products is very low, so this kind of' acid' is not brush acid defined by our hospital, and may not play a good therapeutic role. However, if you brush excessively and endlessly at home and can't adjust it according to your own situation, it will stimulate other problems. Therefore, if' brush acid' wants to use household acid, it is also recommended that patients consult their doctors according to their own conditions, such as the frequency of' brush acid', how long it takes, and whether its skin is suitable for' brush acid', because not all skin is suitable. "
The State Administration of Medical Supplies suggests that some cosmetics can achieve certain cleaning and exfoliating effects, but they are essentially different from "brush acid treatment". Cosmetics are forbidden to express or imply medical functions, avoid improper claims such as "skin rejuvenation" and prevent misleading consumers.
