Plastic surgery technology is becoming more and more mature, providing a lot of convenience for all of you who love beauty, thin face, thin chin, rhinoplasty is a normal thing. But don’t think that plastic surgery can make us do whatever we want. In fact, in each person’s own foundation cosmetic surgery have an insurmountable bottom line. 1, cut double eyelid limit: the widest can only 10mm Double eyelid surgery design is very fine, often calculated in millimeters. The width is mostly within 10mm, usually between 5 and 8mm. Surgery beyond this limit usually has two consequences. First, eyelid ptosis, resulting in incomplete opening of the eyes or can not open the eyes; second is the panic eye, due to the double eyelid is too large, resulting in the eyes always look “staring”. 2, rhinoplasty: Oriental people should not be more than 4mm rhinoplasty pre-designed to pay attention to symmetry, balance, proportionality, the golden triangle and the golden section of the law, lines or curves, harmony and coordination, the principle of natural beauty. These potential factors determine the aesthetic proportion of the nose and face, so the Oriental rhinoplasty should not exceed 4mm. If the nose job exceeds this limit, the nose will look like an “elephant” nose, and the nose will sway from side to side. In addition, too much implantation of prosthesis will make the nose skin taut and thin. 3, injection of botulinum toxin: a maximum of 100 units Botox botulinum toxin because of the significant face thinning effect, but also can remove dynamic wrinkles, so it is very favored by the beauty seekers. However, it should be noted that the amount of Botox is not the more the better, too much may turn your face into a “plastic face”, affecting facial expression. Generally speaking, the maximum number of Botox injections should not exceed 100 units. In addition, if the injection doctor is not familiar with the facial nerve and muscle anatomy, the injection site is not accurate, the use of concentration, the dose is too large, may make the whole face become paralyzed, the face has no expression, as wearing a mask. 4, breast augmentation: each side of the filler should not be more than 400ml Chest to pay attention to the feel, texture, beauty, the size should be appropriate, not the bigger the better. A hemispherical chest looks fake. Too much or too large filler is forced into the breast, which not only has no aesthetic appeal, but also squeezes the internal physiological structure of the breast and affects the health of the body. Fillers implanted in the breast should not exceed 400 ml per side, if the implant is too large for the volume of the skin and the corresponding tissues, it may leave adverse consequences that can be detected with the naked eye or palpable under the skin, which is hazardous to health. 5, liposuction: a more than 4000ml can lead to shock About liposuction, plastic surgery textbooks advocate liposuction of up to 3000ml. But the actual operation process, the total amount of suction fat should generally be controlled within 4000 ml, even if the physical quality of the young beauty seekers, the total amount of one-time suction fat should not exceed 5000 ml. For the sculpture of the body, it is more important to the whole proportion of the body and the shaping of the curve of each part. 6, autologous fat filling: rather less than more a small number of times A lot of beauty seekers for autologous fat filling there is such a misunderstanding: consider the survival rate of autologous fat, injection of autologous fat, the more the better, do not know that this misperception will cause serious consequences. For example, too much filling will lead to fat accumulation, unevenness, epidermal bulging and other phenomena.
