Cosmetic surgery is a voluntary or elective surgery that is performed on normal parts of the body with the only purpose of improving a person’s appearance and/or removing signs of aging. In 2014, nearly 16 million cosmetic procedures were performed in the United States alone. The number of cosmetic procedures performed in the United States has almost doubled since the start of the century. 92% of cosmetic procedures were performed on women in 2014, up from 88% in 2001. Nearly 12 million cosmetic procedures were performed in 2007, with the five most common surgeries being breast augmentation, liposuction, breast reduction, eyelid surgery and abdominoplasty. The American Society for Aesthetic Plastic Surgery looks at the statistics for 34 different cosmetic procedures. Nineteen of the procedures are surgical, such as rhinoplasty or facelift. The nonsurgical procedures include Botox and laser hair removal. In 2010, their survey revealed that there were 9,336,814 total procedures in the United States. Of those, 1,622,290 procedures were surgical. They also found that a large majority, 81%, of the procedures were done on Caucasian people. The American Society of Plastic Surgeons (ASPS) estimates that more than 333,000 cosmetic procedures were performed on patients 18 years of age or younger in the US in 2005 compared to approx. 14,000 in 1996. This is significant because it encourages younger people to continue these procedures later in life. The increased use of cosmetic procedures crosses ethnic plastic surgery in the U.S., with increases seen among African-Americans, Asian Americans and Hispanic Americans as well as Caucasian Americans. In Europe, the second largest market for cosmetic procedures, cosmetic surgery is a $2.2 billion business. Of 1191 UK newspaper articles, 89% used the term 'plastic surgery' in the context of cosmetic surgery.
