Abdominal etching, also known as high-definition liposuction, is a surgical procedure that enhances the appearance of the abdominal muscles, aiming to create a more defined six-pack or washboard stomach. It involves carefully removing and sculpting fat to highlight the natural contours of the abdominal muscles, particularly the rectus abdominis muscles and the linea alba. The ideal candidate for this procedure are individuals who are relatively fit but have stubborn abdominal fat that they want to reduce, and who already have a degree of underlying muscle tone.
