However, while women do not shy away from enjoying the pleasure and surprise changes brought by micro-plastic surgery, some sequelae left by micro-plastic surgery will gradually emerge. If you are also impressed by the effect of micro-plastic surgery, let's take a look at these hidden dangers first. Botox injection makes the face stiff and the contours of the left and right faces asymmetrical. Static lines can be removed by injecting Botox, and it also has a good "fine-tuning" effect on contour problems such as masseter muscle. Botulinum toxin mainly acts on muscles, so it may cause facial stiffness, limited expression and asymmetric facial contour after operation. Hyaluronic acid fills the skin with swelling and itching. Rhinoplasty with hyaluronic acid injection is a very common micro-plastic surgery. Because hyaluronic acid itself exists in human skin and connective tissue, the safety factor of this kind of microbridge is high. However, the quality of hyaluronic acid filler for injection sold in the market is uneven, which is easy to cause skin itching, swelling and other rejection reactions. Laser cosmetic purpura. Laser beauty can be used to remove wrinkles, whiten and fade acne marks. After laser treatment, the skin mucosa may appear purpura due to bleeding injury, accompanied by concave-convex feeling, which is purple at first, then dark red, and will disappear after about two weeks. The skin contour of autologous fat transplantation is uneven. Compared with other fillers, the safety factor of autologous fat transplantation is higher. Autologous fat transplantation is generally used to fill collapsed cheeks and breast enhancement. It is necessary to take your own fat tissue and inject it into the parts that need improvement after phacoemulsification. However, it is easy to have uneven skin on both cheeks after operation. White spot and thrombus of whitening needle. Whitening needle is generally suitable for stubborn spots and pigmented acne marks and scars. Because of its strong antioxidant capacity, the injection of whitening needle may destroy the activity of normal melanocytes and lead to the production of white spots. In addition, coagulation acid as a hemostatic agent may cause the problem of subcutaneous vascular occlusion.
