The common side effects of whitening injection are that some people will have temporary nausea and vomiting, blood pressure drop and dizziness after injection, but these are normal reactions from a professional point of view, because the L- vitamin C component contained in whitening injection needs to be dripped quickly (250ml for about 30 minutes), otherwise it will be oxidized and weaken the effect. In addition, some women will have less physiological periods, so women in menstrual period are also reminded not to carry out injection activities, so as not to cause poor menstrual blood discharge and local congestion. It is not suitable for injection during pregnancy and lactation.

In order to avoid some frequent side effects, we can start with some precautions, such as not over-sunbathing, sunbathing or spa for one month before treatment, and not doing laser, peeling off skin and changing skin with fruit acid for one week before treatment. If there are people who are sensitive to light, have skin lesions, have abnormal immune system, are pregnant or take special drugs, they need to consult a doctor first, or people with multiple inflamed and suppurative wounds are not suitable. At the same time, the injection site should not be damp as much as possible within 24 hours after operation, and the frequency of whitening injection should not be too high. Twice a week is already high density, and the whole body whitening is generally continuous 12 times.
