A cosmetic surgery facelift is a generally safe procedure but as with all types of surgery there are risks and possible side effects or complications that one should be fully aware of before deciding to undergo this, or any type of cosmetic surgical procedure.
One complication of any operation can be excessive bleeding. Others include possible infection, loss of hair to some areas, skin necrosis, and either temporary or permanent nerve impairment in the area. A sense of numbness may be felt for a few months during the healing process, but some patients may have even more drastic nerve issues or may never regain normal sensation.
