Over time, the level of fat and collagen decreases in people. Therefore, it causes loss of volume on face, resulting in pits and wrinkles.
Hyaluronic acid used in filling applications reduces pits and wrinkles on the face by drawing water around the area where it is injected.
Fill applications are completed in about half an hour. It starts to show full effect after 2 weeks. This effect lasts up to 12-18 months depending on type of filling substance and area of application.
