Some people think that whitening needle is once and for all, and the skin will turn white after injection. In fact, whitening needles also have their own maintenance cycle. Ok, let's take a look at how the experts of Yanshi medical beauty in Beijing introduced it. Myth 1: whitening needle is not intramuscular injection. Don't be misled by advertising pictures! Whitening needles are not injected into muscles, but enter the human body in the form of drops. The injection frequency is usually once a week, and 12 times is a course of treatment. Simply put, the ingredients of whitening needle are mostly antioxidant ingredients, including glutathione, tranexamic acid and vitamin C. Glutathione can help the body detoxify and resist oxidation. Tranexamic acid can inhibit the formation of melanin and is used in many whitening products. Of course, different doctors in different medical institutions will have different formulas, and whitening needles are also made in China and imported. Ginkgo biloba extract is added to the formula of Taiwan Province Province Edition, which can speed up the metabolic function of the body and help us get rid of bad things, thus making the skin bright, but because of this, it will also affect the blood coagulation function of the body, so attention should be paid to avoiding menstrual cycle injection when using this formula. Myth 2: whitening needle is once and for all, not once and for all. It uses the principle of anti-oxidation to inhibit the formation of melanin, and can not change a person's own physique. After whitening injection, it will return to its previous state with the gradual production of melanin. Therefore, after whitening injection, you should pay special attention to sun protection and don't let your whitening results go up in flames. Myth 3: whitening needle is absolutely safe. Some beauty and medical institutions say that whitening needles are "absolutely safe, which is equivalent to' not treating diseases if they are sick' and have the effect of refreshing and strengthening the body". But if you are responsible for your health, you can't follow the trend of stars, and all drugs should be used with caution. Only by knowing more about whitening needles can we fully understand whitening needles. After all, everything has two sides, both advantages and disadvantages. The disadvantage of whitening needle lies in whether the plastic surgery institutions and injection products you choose are regular products recognized by the state. At the same time, Beijing Yanshi medical beauty experts also pointed out that the choice of beauty should be rational, and we must go to a formal professional plastic surgery institution to ensure the safety and effect of the operation.
