The formation of under-eye grooves may be due to heredity, age, and staying up late for a long time. 1. Genetic factors: If one or both parents have more obvious eye grooves, the probability of children’s inheritance is relatively higher. If it affects the aesthetic appearance, you can go to a regular hospital and use fat filler to improve it. 2. Age factor: with the increase of age, the loss of skin moisture and collagen, it is easy to form the end of the eye groove. It is recommended to eat more collagen-rich food, or eye collagen filler, etc., can be improved. 3. Stay up late for a long time: If you stay up late for a long time playing with your cell phone, your eyes do not have enough rest, which may lead to the formation of under-eye grooves. It is recommended to rest more, ensure enough sleep, or inject hyaluronic acid under the guidance of the doctor to improve.
