Often beauty ladies consult the so-called “whitening injection”, due to the Chinese people “a white cover a hundred ugly” traditional concepts and the relentless pursuit of “white”, resulting in a variety of organizations to play the “whitening injection” brand, many people want to ask the current market “whitening injection” is really effective? “whitening injection” card, many people want to ask the current market “whitening injection” really have effect? In addition, there are some obvious side effects? Here also and everyone to popularize it. What is “whitening injection”? The so-called “whitening injection” the most common ingredients are glutathione, tranexamic acid and vitamin C, etc. In fact, these drugs are very cheap, but in some “organizations” they are combined and injected intravenously, and a nice name! “whitening injection”, it is sold as “sky-high prices”. Are “whitening injections” really effective? Theoretically, it is effective, and in practice, it should have some effect, but there is a lack of large sample randomized double-blind clinical studies. Glutathione, tranexamic acid and vitamin C, these ingredients have antioxidant, inhibit the role of tyrosinase in melanocytes (which plays an important role in melanin synthesis), reduce the formation of melanin, so as to achieve the effect of whitening, but mainly for special pigmentation diseases. It is not recommended if you have naturally darker skin. Which skin diseases can I use “whitening injection”? Mainly for melasma. For the treatment of pigmented diseases, the first step is to go to the hospital for a clear diagnosis. If it is melasma, you can try “skin whitening injection” treatment after weighing the pros and cons. If it is freckles, periorbital nevus, nevus of Ota, post-inflammatory hyperpigmentation, etc., then the “whitening injection” treatment will not be effective. Is the effect of “whitening injection” permanent? Definitely not. These treatments do have some effect on pigmented diseases such as chloasma, but since the inhibitory effect of any medication on melanin synthesis by melanocytes is temporary, there is still a possibility of recurrence in the future after stopping the medication. If a normal person is born with darker skin color, it is not recommended to use it because the effect decreases in the long term and it increases the incidence of adverse reactions. The advertisements are all lies. Special reminder Because the “whitening injection” requires a long course of use, usually more than 1-2 months to see the effect, most need to use more than 6 months to achieve the best results. Long-term use may have adverse reactions, must be used under the guidance of a professional doctor. Don’t try it easily! “Whitening injection” may have adverse reactions, serious cases can be life-threatening 1, vitamin C: whitening use of vitamin C, the general dosage is relatively large. Long-term large amounts of vitamin C may cause urinary stones, diarrhea, skin red and bright, headache, urinary frequency, gout aggravation, nausea, vomiting, stomach cramps, etc., long-term large amounts of (2 to 3g per day) can cause scurvy after stopping the drug. 2, tranexamic acid: can inhibit the role of fibrinolytic enzyme, mainly used for hemostasis, anti-metamorphic reaction, anti-inflammatory. Because tranexamic acid can compete with tyrosinase, thus inhibiting melanin synthesis, but also has the effect of inhibiting blood vessel formation, reduce erythema, so there is a clear effect on chloasma, and its “whitening” effect for vitamin C 50 times. The main adverse reactions are: loss of appetite, nausea, vomiting, heartburn, low menstrual flow, itching, skin rash. Long-term use should pay special attention to monitoring blood, prothrombin time, etc., to prevent thrombosis. 3, glutathione: side effects are relatively rare, but the role is also the weakest of the three components. Occasionally nausea, vomiting and headache, rare rash. These three ingredients are relatively “standardized” whitening ingredients, if some “institutions” in order to cater to the “customers” want to see quick results in the psychological, and in the If some “organizations” in order to cater to the “customers” want to see quick results, and in the “whitening injection” to increase the hormone or other prohibited ingredients, it is more harmful. Is there a safer treatment? With the continuous development of photoacoustic-electric technology and hydrazine, hydrazine and laser are more and more widely used in the treatment of pigmented diseases skin diseases, the effect is good, and high safety, can be the first choice. In addition, topical hydroquinone and its glycoside derivatives, azelaic acid and fruit acid chemical peeling can also be considered. Finally, I hope that everyone rational “beauty”, do not for the sake of beauty and affect the health, or even life-threatening, the loss is not worth it. At the same time, do not have unrealistic expectations, the role of the current “whitening” treatment is limited, and are temporary, in most cases, after stopping the treatment with time may recur, there is no treatment is once and for all. It is safer and more reliable to pay attention to sun protection and moisturizing of the skin on a daily basis.
