The tear trough is very deep since childhood, looks the same as drug addiction, how can not cover, eye cream bought do not know how much, thousands of hundreds of eye masks do not help, super old. Many people have the problem of tear troughs, so that the beauty is greatly reduced, and then the good-looking eyes encounter tear troughs are also no longer luster, photo looks old and haggard, what makeup is no spirit. Many people think that tear troughs appear only when they are old, but in fact, they are not. Tear troughs are generally congenital, and people with thinner skin under the eyes often have them more pronounced than the average person. The tear troughs are usually congenital, and people with thinner skin under the eyes often have a more pronounced appearance than the average person. Tear troughs Tear troughs are a groove that starts at the inner corner of the eye and appears on the nasal side of the lower eyelid. The junction of different muscles around the eye, the different tightness of the skin on the lower lid and cheek, and the strength of the muscle ligaments can all lead to tear troughs. In some cases, it can even extend to the cheeks. Tear troughs are not the same as bags under the eyes. Because of the contrast between the sunken tear troughs and the surrounding skin, the lower lid tissues look a little bloated and protruding, so it is easy to think of them as bags under the eyes, but in fact that is just the illusion of deepening tear troughs. For people with tear trough ligaments that are not very strong and do not have bags under the eyes, but only skin depressions, only a small amount of hyaluronic acid injection is needed. When hyaluronic acid is injected into the tear trough area, it will fuse with the original hyaluronic acid in the tear trough area, and the skin will expand and the tear trough will rise and flatten. 2.Eye bags type tear trough If the tear trough depression is because the tear trough ligament is relatively strong, or even a little bit of eye bag problem has appeared, it is recommended to deal with eye bags and relax the tear trough ligament first. Through scarless eye bag surgery, you can operate from the conjunctiva inside the eye to remove the eye bag fat, and fill in the tear trough area by transposing the eye bag fat while relaxing the tear trough ligament. In this case, there is usually no need to inject hyaluronic acid. 3.Older tear troughs Older tear communication is often not just a tear trough depression is obvious, but also accompanied by heavy eye bags, skin laxity, fat loss, etc. Often only rely on eye bags and fill tear troughs and other ways can not completely solve the problem, but also more difficult, at this time need to carry out comprehensive treatment, need to combine with facial lifting projects. Hyaluronic acid filling injection process 1.Mark the injection location, take photos and sterilize; 2.Inject 2% lidocaine plus epinephrine 0.03～0.05ml intradermally at the marked location, with slight finger pressure; 3.After 10～20 minutes, the anesthesia site becomes pale, use 30G1/2 syringe to enter the needle at the central anesthesia point, cap to the closest to the nose; 4.Inject hyaluronic acid first to the orbicularis oculi muscle at the deep surface of the maxillary embedding point, and then inject outward to the deep surface of the orbicularis oculi fixed ligament. Use a combination of staggered injection and linear injection technique, and the injection position should not be too shallow; 5. Perform a backward injection in the dermis and inject small drops of hyaluronic acid in a slow and orderly manner, with the injection volume of 0.1~0.45ml on each side of the lower lid, with 0.2~0.3ml being more common; 6. Exit the injection needle for hyaluronic acid filling and use even strength finger pressure to make the injectable spread out evenly. Tear trough filling injection technique is not as simple as a shot Filling tear trough seems to be simple, just as simple as a shot, but in fact it requires extremely high injection skills and rich experience, whether it is deep filling or shallow modification, there are many considerations. The depth of injection, the amount of injection, the angle of the needle and so on, and also should choose the right product. 1, push injection should be slow, while pushing injection while shaping Injections must be slow, and need to push the drug while shaping. Because the skin at the tear trough is thin, so that the filler can be evenly spread in the depression of the tear trough to achieve the best results. 2.Injection level on the periosteum Tear trough filling is recommended to be injected to the deeper layer and injected to the periosteum. If only injected in the epidermis, it is easy to have a slight bruise; if injected close to the periosteum, it is more natural and not easy to have bruise, but still need to consider the individual face condition to decide the injection position. 3, play in the shallow early effect is good, long term problems Some doctors will find that if you play deep how can not lift the tear trough, will choose to play shallow flat lay up, although the early effect is very good, but it is easy to have problems. However, the skin of the tear trough is very thin and the orbicularis oculi and the subcutaneous tissues are difficult to peel off, so it is easy to hit the orbicularis oculi when injecting, forming a fiber package, and the fiber package has no blood flow, so it is easy to gather into a ball. Also, there is melanin in the superficial layer of the skin, so if the injection is too shallow, the melanin will be active and pigmentation will occur. If the injection is too much, it is easy to form hard knots. 4, if you must inject shallow, you can only inject a small amount of deep injection into the needle point less, the bruising rate is low. If not played against the periosteum, it is easy to be carried by the orbital diaphragm fat, and when hitting the orbital diaphragm fat, it will expand a lot and cause pseudo eye bags. If the injection is too much, redness and swelling will easily occur. If you must inject shallow, you can only inject a very small amount and massage evenly. 5, pre-operative ice and post-operative pressure is important The tear trough is rich in blood vessels, it is easy to bruise, pre-operative ice so that capillary constriction, can be a good prevention of bleeding. At the same time, pressure should be applied in time after the injection, even if there is no bleeding, to prevent bruising a few days after the injection. 6.How to avoid bruising? Among the injections try to get a good grasp of the area into the needle, it is best not to have too many needle eyes, because there are many small capillaries at the tear trough, once touched, bruising will occur, if it appears it usually takes about 5-10 days to fade, so be sure to avoid it. In areas where the tissue is very thin, almost a layer of skin without any fat layer, injection must be careful, especially on the issue of injection volume, especially to draw attention.
