Enriching the earlobe is a method to make the earlobe that is too thin and too small plump and round through various medical means. Autologous fat-rich earlobe will not cause changes in the endocrine environment of human body, will not cause damage to the tissue of the injection site itself, and will not have adverse effects on future life. Because it is autologous tissue, its biological characteristics are far superior to any prosthetic material, so it is non-toxic and harmless to itself and will not produce immune reaction and rejection. Fat particles are easy to obtain and rich in tissue sources.
