Teach you a trick to ensure that you will know the truth the next time you try these strange methods of rhinoplasty, face-lifting, body-shaping or the latest medical technology-this is the medical paper search method. Use any academic search engine-Chinese search engine guide network, 360 academic, Baidu academic, etc. Search papers to find out if there is such a method, technology or equipment in medicine. As far as the plastic surgery industry is concerned, the most authoritative medical journal is PRS (Plastic and Reconstructive Surgery, official website). If you can't search in English, please recommend this method, technology or equipment (doctor? ) provide evidence such as paper index.
