Although whitening needles can whiten human skin in a short time, long-term use will still have related side effects. One of the main components of whitening needle is tranexamic acid, which has the risk of causing menstrual bleeding. Very few people with special physique who are allergic to vitamin injection may also cause allergic reactions by using whitening needles. In addition, long-term injection of whitening needle may cause liver and kidney damage. At present, there is no whitening needle approved for clinical treatment in China, so beauty seekers should be cautious when carrying out related cosmetic treatment.
