Dermal fillers help to diminish facial lines and restore volume and fullness in the face. As we age, our faces naturally lose subcutaneous fat. The facial muscles are then working closer to the skin surface, so smile lines and crow’s feet become more apparent.
Common fillers including hyaluronic acid (marketed as Juvederm), Radiesse and Restylane, are particularly suited for fine lines and wrinkles around your mouth.
The facial skin also stretches a bit, adding to this loss of facial volume. Other factors that affect the facial skin include sun exposure, heredity and lifestyle.
