In these cases, surgery is often necessary for medical reasons in addition to aesthetic concerns. Another common reason for cosmetic surgery is to enhance one's appearance and improve self-esteem. Many people choose to undergo surgery to address physical features that they are unhappy with, such as a disproportionate nose, small breasts, or sagging skin. By improving these features, patients can feel more confident and comfortable in their own skin. Some individuals also opt for cosmetic surgery as a way to turn back the clock and combat the signs of aging.
