Dermal fillers are injectable substances designed to restore volume, smooth out wrinkles, and enhance facial contours. When it comes to smile lines, also known as nasolabial folds, dermal fillers work by filling in the crease where the skin has lost elasticity and volume over time. This results in a more youthful appearance by softening the lines and creating a smoother transition from the nose to the corners of the mouth.

In addition to improving smile lines, dermal fillers can also enhance the lips. By adding volume and definition, they can create a fuller lip look, balance asymmetry, or even improve the shape of the lips. This can significantly enhance facial aesthetics, giving a more vibrant, youthful appearance.
