The under-eye area is known as one of the most sensitive areas due to the blood vessels and fatty tissue under the thin skin layer. Dark circles under the eyes may occur for various reasons such as fatigue, intense work schedule, stress, insomnia, gravity or exposure to toxic substances. A younger and livelier appearance can be achieved in a short time with the under-eye light filling process. While local anesthesia or topical anesthetic creams can be used around the eyes before the procedure, the process can be made more comfortable. If there is any dirt, it is cleaned. Afterwards, the filling process begins with all the necessary small touches. While the filling process is being applied, light is slowly applied to the area and the duration of this process usually varies between 15-30 minutes. Under-eye light filler heals completely within 2 weeks.
