Dermal Fillers are soft tissue fillers that get absorbed naturally by the body in order to create a smoother and fuller appearance on the face. Also known as wrinkle fillers, these are used to enhance facial features like lips, cheeks, chins and sometimes even the back of the hands. Successful results will depend on the underlying tissue structure and the volume and type of filler used. The time that the effect lasts depends on the filler material and the area where it is injected.
