Tear trough is the first symptom of aging. Tear trough appears, the face will look 5 years old, recently there is a very popular “face age” software, is through some facial features to calculate the age of the face, the tear trough is one of the key points of age, remove the tear trough, for age subtraction. Tear trough is a concave groove that appears on the side of the lower eyelid against the nose, starting from the inner corner of the eye, due to the atrophy and sagging of the soft tissues at the lower edge of the orbital septum. In some cases, it can even extend to the cheeks. Because of the contrast between the depression of the tear trough and the surrounding skin, the lower eyelid tissues look a bit bloated and protruding, which can be easily thought of as bags under the eyes, but in fact, it is only the illusion that the tear trough has become deeper. Tear troughs are generally congenital, and are often more pronounced in people with thinner skin under the eyes than in the general population. However, the 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 age, the subcutaneous fat shrinks, the skin thins and sags due to reduced elasticity, and the tear troughs on the inner side of the lower eyelids become visible, and the “bags under the eyes” appear. The appearance of infraorbital hollows gives a tired look that cannot be improved by face lifting, threading, Botox, or even skin resurfacing surgery. Usually girls hide the tear troughs by applying concealer with make-up, but make-up can only hide the tear troughs when there is make-up, not a long term solution, and filler injections to improve the tear troughs turn out to be the most effective way. Choice of fillers There are many types of fillers available, and the ones that are more commonly used are autologous fat and hyaluronic acid. Autologous fat is taken from the subcutaneous fat of the abdomen or thighs, and then injected into the tear trough after standing or centrifugation, the advantage is that it is taken from our own tissues, no reaction, but the disadvantage is that there is a certain degree of uncertainty. Hyaluronic acid is the most common synthetic tissue filler, and it is important to be aware of the need to watch what happens later in the injection. Some hyaluronic acid fillers are less cross-linked or less viscous and have a tendency to absorb water after injection, so localized swelling or edema can occur after injection. Try to stay away from fillers with long-lasting particles, as granulomas, encapsulation or even sclerosis may occur due to the unpredictable properties of these fillers. Distinguish whether the signal of your facial aging is the formation of bags under the eyes or deepening of the tear trough. If it is puffy bags under the eyes to be improved by eye bag removal, and if it is the deepening of the tear trough caused by facial aging to be improved by filling the tear trough with autologous fat or fillers, treat the symptoms and choose the right procedure for you to subtract your age.
