Feng: "There is no age limit, but I think because cosmetic surgery or non-surgical cosmetic surgery involves people's psychological state, it is best to be an adult. /kloc-people over 0/8 years old have their own opinions and evaluate their own image. In this case, it is better to accept plastic surgery. Of course, some people are under 18 years old, and some parents take us for plastic surgery. After communicating with the parents and guests who had plastic surgery, we felt that his request was reasonable and could help him solve it, so we accepted it. At present, it is generally cosmetic surgery. According to the natural population, it is concentrated in the 30 s and 40 s, and the elderly also do it. However, the suffering of the old man and his thoughts are related to the needs of society. Therefore, the most obvious and concentrated population is concentrated at the level of 20-50 years old.
