Medical procedures, especially surgery, come with side effects. Similarly, cosmetic surgery has some risks and side effects as well. Infection and bleeding are the leading side effects of cosmetic surgery. Although these side effects do not develop in all cases, there is nominal risk in every surgery. Infection presents with redness, pus and bleeding from the site of incision, fever, sever and persistent pain and severe swelling. Other side effects vary with the type of procedure employed for cosmetic surgery.
