Eyes play a pivotal role in the overall beauty of the face, however, even the most beautiful eyes can be overshadowed by the appearance of tear troughs, so there is an increasing demand for tear trough injections. However, the tear trough is a more difficult area to master than other parts of the face, and it is also one of the areas most prone to complications. Therefore, how can you avoid complications when performing tear trough injections? What are the injection techniques that need to be mastered to completely solve the problem of tear trough injections? Tip 1: Remove Tear Troughs by Addressing the Causes Tear troughs are categorized as young, old, and bags under the eyes, and not all types of tear troughs can be resolved with filler injections. Not all types of tear troughs can be solved by injecting fillers. Young tear troughs and old tear troughs can be improved by injecting fillers in a “filler” way. The difference between the two is that the younger tear troughs are mainly due to the ligaments being too tough by nature, causing the skin to be pulled and indented. In this case, the indentation is directly in the skin, and the amount of filler is very small and needs to be very precise, making it unsuitable for autologous fat fillers. Under-eye bags type tear troughs, on the other hand, need to undergo under-eye bag removal surgery first, for the situation to see if you need to solve the problem of tear troughs. Tip 2: Elderly tear trough should be comprehensive treatment Above 40 years of age, tear trough depression is obvious, accompanied by skin laxity is obvious, often only fill the tear trough, and can not completely solve the problem, at the same time the difficulty is also larger, at this time the need for comprehensive treatment, need to be combined with the face lifting injections. Tip 3: Choose the right product If you choose hyaluronic acid to fill the tear trough, you should choose a product with a small cross-linking degree or small molecular weight. Because of the thinness of the skin in this part of the tear trough, if you choose a product with a high degree of cross-linking or a high molecular weight, it will be easy to produce “lumps” or hard to touch. Tip 4: Prefer deep rather than shallow, prefer less rather than more The tear trough is recommended to be injected into the deeper layers, into the periosteum. Deeper injections have fewer entry points and lower bruising rates. If you don’t hit against the periosteum, it is easy to be moved by the orbital diaphragm fat, and if you hit the orbital diaphragm fat, it will be swollen to a great extent, resulting in pseudo bags under the eyes. Redness and swelling are easy to occur if injected too much. If you must inject superficially, only inject a very small amount and massage evenly. Some doctors will find that if they play deep, the tear trough can not be lifted up, and they will choose to play shallow flat laying up, although the early effect is very good, but it is easy to have problems. Because playing shallow should not hit the dermis, should hit the fascia, but the tear trough skin is particularly thin, orbicularis oculi muscle and subcutaneous tissue is difficult to peel away, so the injection is very easy to hit the orbicularis oculi muscle, the formation of fibrous parcels, fibrous parcels and no blood transport, easy to get together into a ball. There is melanin in the superficial layer of the skin, if the injection is too shallow, it will make the melanin active, and there will be discoloration. If the injection is too much, it is easy to form hard knots. Tip 5: Remember not to inject into the following places 1, do not touch the opening of the tear duct, where there are large blood vessels, such as bruises and hematomas will last for half a year, regardless of whether the injection is deep or shallow; 2, avoid injecting into the orbital and orbicularis oris muscle, because the rotation of the eyeballs will lead to the movement of the fat at the bottom of the orbital septum, which is easy to form pseudo bags under the eyes. When injecting, you can let the client’s eyes look upward, and at the same time take the left hand fingers against the orbital rim, in order to sense the position of the injected product at any time, and avoid injecting into the orbital area. Tip 6: Push the injection slowly, while pushing the injection while molding The injection must be slow, and need to push the medicine while molding. Because the skin at the tear trough is thin, so that the filler can be evenly spread on the tear trough depression, in order to achieve the best results. Tip 7: preoperative ice and postoperative pressure is very important The tear trough is rich in blood vessels, it is easy to bruise, preoperative ice so that capillary contraction, can be very good to prevent bleeding. At the same time, you should press in time after injection, even if there is no bleeding, you should press immediately to prevent bruising for a few days after injection.
