The main ingredients are known as acid, glutathione, vitamin C, vitamin B6 and other drugs in melanin formation, catabolism and other links, which can reduce the content of melanin in the skin, thus making the skin white.
Why does not recommend a whitening injection? But why is the white needle banned in the US? Is the side effect of the whitening injection really so big?
1. The effect of whitening is not long.
The formation and metabolism of melanin in skin cells is a long-term process. A large amount of interference with melanin circulation in the short term cannot solve the problem of melanin circulation in the skin cells after the drug is stopped, so the effect of whitening injection cannot be maintained for a long time.
2. Basically ineffective in natural black
Natural black refers to the congenital skin black, whitening for a short time, the sudden increase of melanin, such as skin exposure, the effect is more obvious, the effect of natural black is not significant or no effect. So don't waste your money on your own black sister.
3. Excessive use may lead to side effects
Although these whitening injections are medically acknowledged as safe and effective and are widely used, it is not proven whether the composition of the ingredients is safe or not. Moreover, excessive and illegal use can be harmful. Excessive use of trans-acid: the use of tranexamic acid is restricted by doses, usually 2% to 3%. Because it is known that acid is whitening by inhibiting melanin formation, and melanin protects us from skin cancer, so the excessive use of clear acid may increase the risk of skin cancer.
In addition, it is known that acid and coagulant effect. Therefore, before and after the menstrual period, remind you not to injecting whitening injections containing acid.
Glutathione overdose: glutathione also has a strict dose limit when used, 323~646mg times a day, 1~2 times a day. And there may also be adverse reactions, such as nausea, vomiting, headache and rare rashes.
Vitamin C overdose: compared to the first two, vitamin C looks much more delicate. Since human beings cannot synthesize vitamin C by themselves, they need to supplement it through food. And the amount of vitamin C intake is neither too much nor too small, usually between 60mg~1g.
Excessive intake can lead to diarrhea, clotting and other diseases. More than 5g per day will lead to hemolysis and even life-threatening. The lack of intake can cause scurvy.
In addition to the above, the whitening injection in a short time in a large number of use, and may cause deep venous thrombosis, stone and other serious complications, these tendencies should be strictly restricted to use.
