For example, blood can collect under the skin, leaving a blue-black mark, which fades gradually. Nerve injuries can also occur, although these are rare. Sometimes, face lifts can give a mask-like look to the face, resulting from nerve injuries. Like all other surgeries, cosmetic procedures also carry a risk whenever general anaesthesia is used. It is essential to find a good surgeon and to discuss the pros and cons before going in for cosmetic surgery.
Word of mouth is a good way.
If you can talk to people who have gone through such procedures, you can get a first hand account. Your own family physician may be able to refer a good plastic or cosmetic surgeon to you. There is no harm in asking questions. Find out everything you want to know. Ask for Before-After photographs.
