Generally, normal women's nipples are uniform cylindrical, with a certain proportion of thickness and length to areola and breast, standing forward, symmetrical on both sides and full of beauty. However, the nipple is too long and too thick, losing its normal proportion and even drooping, and its appearance is not beautiful. When female friends face such problems, they can be improved by nipple reduction surgery. Nipple reduction refers to the method of surgical excision, which removes the nipple that is too high or too long, shrinks it and sews it into a nipple of appropriate size. The common nipple reduction methods include unilateral nipple resection and partial nipple resection to reduce the nipple.
