The tear trough refers to a depression in the infraorbital rim area. Patients can effectively improve the tear trough through plastic surgery such as hyaluronic acid injections and surgical excision, but the specific treatment depends on the patient’s condition. In order to improve the tear trough, patients can have local hyaluronic acid injections, which generally fill and flatten the tissues, thus making the tear trough subside. However, the specific maintenance time varies from person to person, usually not for a long time. If the results are not good, patients may also consider traditional surgical excision, which involves removing loose skin to improve the tear trough. However, surgery does not mean a permanent solution, as the tear troughs will form again as the eyelid skin loosens with age. Hyaluronic acid injections improve mild tear troughs, and in more severe or older patients, eye bag surgery can be performed along with orbital fat release and filling with autologous fat. It is recommended that patients with significant tear troughs seek prompt medical attention to evaluate their condition and follow their doctor’s instructions.
