People often point to the bags under the eyes and say, “Look, this is the sleeper silkworm. The sleeper silkworm, also called eye moss or cicada, is a slightly elevated area immediately below the eyelashes, which looks like a baby silkworm lying across the edge of the lower eyelashes, especially when smiling. Eye bags are also located immediately below the lower eyelashes, but a little further away from the eyelid, and usually have a drooping shape. Sleeping silkworm eyes are very attractive and easily give others a feeling of closeness. Hyaluronic acid injections are the most effective and quickest way to fill the silkworm with hyaluronic acid: Injecting hyaluronic acid to fill the silkworm, slowly and evenly injecting the right amount of hyaluronic acid under the eye to fill the silkworm, to immediately tighten the eye skin and plump the effect of the silkworm, so that our eyes immediately become three-dimensional, deep and lovely. After hyaluronic acid injection, it will cause redness and swelling or bruising under the eyes, so after the injection, we will usually take the measure of applying ice packs to reduce the redness and swelling under the eyes before we can go home. During the icing process, you will also be observed for any other discomfort, and if you find any discomfort, please communicate with your doctor immediately. How long do hyaluronic acid injections last? Hyaluronic acid injections are not permanent, because hyaluronic acid is a component that will be absorbed by the body and will be absorbed and consumed with the body’s metabolism. The maintenance time of hyaluronic acid is only 6-9 months, so you need to repeat the injection if you want to keep the effect for a long time. Because injected hyaluronic acid will be slowly absorbed by the body, so if you want to maintain the effect, you need intermittent injections, once you no longer continue to inject, the effect will slowly fade away and finally disappear completely.
