Some people still look old after removing the bags under the eyes, some people are not old but not young, we only focus on facial wrinkles, sagging skin, but little attention to the tear trough. Even 46.2% of people still don’t know what tear trough is! Tear troughs, nasolabial folds, and marionette lines are the famous “three eight lines” in the medical aesthetics industry. Tear troughs are the first symptom of aging. What is a tear trough? Tear trough is a groove that starts at the inner corner of the eye and appears on the side of the nose of the lower eyelid, making people appear frustrated, tired and old. In some cases, it can even extend to the cheeks. Because of the contrast between the sunken tear trough and the surrounding skin, the lower lid tissues look bloated and bulging, making them easily perceived as bags under the eyes, but in fact that is just an illusion given by the deepening tear trough. How do tear troughs form? Tear troughs are usually congenital and are caused by the atrophy and sagging of the soft tissue at the lower edge of the orbital septum. Tear troughs are often not obvious when you are young, because young people have more subcutaneous fat and tighter skin, so there is only a vague outline. However, as we grow older, the subcutaneous fat shrinks, the skin becomes thinner and sags due to reduced elasticity, and the tear trough on the inner side of the lower eyelid becomes obvious, so the “bags under the eyes” appear. Tear trough removal prefers injectable fillers Tear trough makes people present a tired expression, and these cannot be improved by face lift, buried thread, Botox. Injectable fillers turn out to be the most effective way. If the problem is entirely tear trough, hyaluronic acid injection is the way to go. If there is a combination of bags under the eyes, the bags should be removed first, and then an appropriate amount of fat from the bags should be implanted. Although the principle is simple, the operator’s delicate technique and rich experience are required to fill in beautifully and smoothly. For mild and moderate conditions, one is enough, but for more serious depressions, 2 to 3 are needed. Suitable people: Those with atrophy and sagging of the soft tissue at the lower edge of the orbital septum. Effect of filler: Tighten the sagging skin and make the face appear flat and smooth. Hyaluronic acid filler injects hyaluronic acid in the form of filler into the tear trough to augment the skin and smooth out the collapsed skin, making the eyes look fuller and more radiant. Hyaluronic acid is available in a variety of molecular weights. To achieve the desired cosmetic effect, hyaluronic acid of different molecular sizes and different skin depths are selected for injection. The amount of small molecule hyaluronic acid used to fill tear troughs is around 0.5 to 1.0 cc, depending on the degree of depression.
