Many people want to have a pair of eyes that can smile. When people smile, the orbicularis oculi muscle below the eye face forms a protrusion similar to a baby silkworm, which is often referred to as the “sleeping silkworm”. The silkworms are smooth, elastic, oval, round and smooth, and will be more obvious when you smile. People who have sleeping silkworms have extra attractive eyes. Of course, not everyone will have silkworms, some people have relatively weak orbicularis oculi muscle, will not form silkworms. Thanks to the development of cosmetic technology, plastic surgeons can help you create a pair of lovely “silkworm babies” through serpuloplasty. Fat grafting is a very popular cosmetic procedure these days. Fat particles are injected under the eyelid at the level of the orbicularis oculi muscle to create a silhouette. If the injection technique is not well mastered, the shape of the silkworm will be thick and stiff, losing its original charm and even subtracting points from the appearance. As for the question of whether the skin will become saggy after fat grafting, there are usually two reasons why the skin becomes saggy, one is due to normal aging, and the other is due to sudden and massive weight loss. After fat transplantation, the skin of the recipient area will not only not become saggy, but will also become firmer, and even the skin texture will be more delicate and brighter. For the skin in the fat donor area, the skin has a very strong self-healing function, and the skin will be rebuilt after the fat is extracted and gradually grow back together with the basal tissue, which usually does not cause skin laxity either. Especially when doing facial fillers, the amount of fat needed is very small, and after the recovery period, the tissue in the donor area, including the skin, is almost indistinguishable from the original. If you are very old and have very loose skin, this is not a problem that can be solved by fat transfer alone. If the original is relatively plump, after liposuction surgery extracts a large amount of fat, the skin may look loose in the early stage, but after a period of asking, most of them will also gradually recover.
