Distinguish beauty
There is a Chinese saying "one white covers a hundred ugliness".
In our country, fair skin is regarded as the standard for beauty.
In order to "white into a light", beauty lovers are also doing everything. Now they are no longer satisfied with applying whitening cream, sunscreen, umbrellas, eating lemon... Instead, they pin their hopes on the "whitening needle". A fast food whitening product that can change into "Snow White" in seconds with a single shot.
In this regard, Li Gang, chief physician of plastic surgery at the Second Hospital of Tianjin Medical University, told a reporter from Science and Technology Daily that there are currently no formal whitening injection products on the market in China, and all injection-type whitening products are not reliable and may even endanger health.
The ingredients of the water whitening injection
"Flowing water whitening needles, iron-made ingredients. No matter how the name of the whitening needle changes, it is nothing more than these three core ingredients at work: reduced glutathione, tranexamic acid (tranexamic acid), and vitamins. C." Li Gang introduced that these three drugs were mixed together and injected into the human body through a vein by infusion. A course of treatment was about 10 infusions, once every 3 days, and the administration was completed within 1 to 2 months.
Among these three ingredients, reduced glutathione is a common hepatoprotective drug.
"The reason why it has a whitening effect is because there is a sulfhydryl group on the molecule of reduced glutathione." Li Gang explained that there are many oxygen free radicals in the human body, and these substances will destroy the cells that delay skin aging. , Thereby accelerating the aging of the skin, and also accelerating the production of melanin.
This sulfhydryl group can'attract' oxygen free radicals, and even adsorb these oxygen free radicals, thereby preventing the synthesis of melanin and whitening the skin.
Tranexamic acid is a common hemostatic drug, usually used as a hemostatic drug in the perioperative period.
"The production of melanin requires the participation of tyrosine and tyrosinase to allow melanocytes to synthesize melanin. Tranexamic acid is very close to the molecular structure of tyrosine, so it can compete with enzymes to convert tyrosine into melanin. The process is blocked, that is, the process of melanin synthesis is blocked, so as to achieve the whitening effect." Li Gang said.
Compared with the other two whitening ingredients, vitamin C is a familiar whitening substance. For example, it is often said that eating more lemon, grapefruit, and kiwi fruit can whiten because these fruits are rich in vitamin C.
"Vitamin C has strong antioxidant properties and can scavenge oxygen free radicals in the human body." Li Gang introduced. In addition, vitamin C can inhibit the activity of tyrosinase, block the production of melanin, and reduce the melanin that has been formed to nothing. The melanin precursor can improve the dullness of the skin and achieve a whitening effect.
Health costs after rapid whitening
"Currently, there are no formal whitening needles in the domestic market. Most of these products on the market come from South Korea, Japan and other places, and they have not obtained the sales qualification certificate in Mainland China. They are all "three-no" products." Li Gang said, so whitening In my country, there is no clear operation process and description of drug ingredients for needles.
Reporters inquired on the official website of the State Food and Drug Administration and found that there are no products such as whitening injections that have been registered as drugs.
"In addition, the ingredients contained in these whitening needles have not been approved by my country's Food and Drug Administration for indications. Long-term use will cause some adverse reactions and even serious complications." Li Gang emphasized.
"Reduced glutathione is the strongest antioxidant. Many organs of the human body need it. Therefore, it is only necessary to infuse it frequently and in large amounts.
The whitening effect can only be achieved when the supply of various organs is ensured.
"Li Gang introduced, but long-term over-infusion of such substances can cause symptoms such as anorexia, mild nausea, and severe gastrointestinal mucosal damage and kidney damage.
Clinically, an important complication of the use of tranexamic acid is the promotion of blood clotting. Long-term use can lead to amenorrhea or thrombosis.
"Generally speaking, it is not recommended for elderly women or pregnant women." Li Gang emphasized.
Vitamin C has an antioxidant effect, but if you consume too much, you will experience dizziness in the slightest, and scurvy and other diseases in severe cases.
According to the "Dietary Guidelines for Chinese Residents (2012 Edition)", the daily recommended intake of vitamin C for Chinese residents is 100 mg.
Daily vitamin C dosage exceeding 600 mg can cause frequent urination. Ingestion of more than 1,000 mg can cause skin redness, increase bowel movements and cause abdominal cramps and diarrhea.
"Because vitamin C is a water-soluble vitamin, it cannot accumulate in the body. The excess will be metabolized by the kidneys in the form of oxalate. Excessive intake may cause kidney stones or urinary tract stones." Li Gang introduced, long-term overdose of vitamins C will also have symptoms such as gum swelling, bleeding, subcutaneous petechia, joint and muscle pain, and hair follicle keratosis.
"Besides, what's even more frightening is that in order to save costs, many women who love women buy the above-mentioned medicines by themselves and find someone to dispense them privately," said Li Gang.
It is understood that whitening injections are highly profitable. The cost of injections of reduced glutathione, tranexamic acid, vitamin C and other medicaments themselves is not high. However, in many beauty institutions, it costs a lot to inject a whitening injection. Around a thousand yuan.
Since the whitening needle is generally a fixed standard formula, this also makes many women dare to "take the risk."
"It is more harmful to inject the medicine privately by yourself, so I often hear feedback such as'not obvious white' and protruding blood vessels throughout the body." Li Gang explained that these women are likely to become white under the action of vitamin C, but vitamins The half-life of C in the human body is half a month. After the needle is stopped for a period of time, after vitamin C is metabolized by the human body, if you do not pay attention to sun protection, the melanin will re-precipitate, and the skin will easily "turn to dark"; "Protrusion of blood vessels" is due to chronic phlebitis caused by long-term injection of such drugs.
It is safer to use the smearing method to whiten
So, if you want the skin to turn white quickly, is there a safer and more effective way?
In this regard, Li Gang believes that black skin is not a disease, and it is not white or beautiful. This kind of "appearance anxiety" is completely unnecessary. Don't pay the price of health in order to become white.
"If you have to whiten, then safety must be the first thing." Li Gang suggested that the doctor's principle of treatment must be to apply medicine without taking medicines, to take medicines without injections, and for injections without infusions.
In comparison, it is safer to use smearing for whitening.
In addition, it should be noted that while whitening, sun protection is more important. Li Gang suggests that you should try to apply sunscreen products or use a parasol before going out to prevent the production of melanin is the basis for whitening.
Li Gang emphasized that don't blindly believe in online rumors and advertisements, especially if a whitening product is said to be effective, it is best to stay away from it, because behind the magical effect, heavy metals such as lead and mercury may be at work.
"This is the same reason that tomatoes ripened by auxin are not as good as they grow naturally," he said.
A report released by the World Health Organization shows that some whitening products have complex ingredients, including hydroquinone, which can inhibit the production of melanin in the skin, steroids used to treat severe dermatitis, and the toxic metal element mercury.
Long-term use of such whitening products may damage the kidneys, causing skin rashes, discoloration, or scars.
Finally, Li Gang suggested that, theoretically, the ultimate white skin color of the human body is the color of the skin on the inner thigh. "People who are born with dark skin should not be tossing about. The powerful power of genes cannot be changed by external products. We do not reject whitening within the normal range, but do not easily be fooled by illegal businesses. Everyone should have confidence in their appearance. , It can be beautiful even if it's not white." He said.
