Dermal fillers help to diminish facial lines and restore volume and fullness in the face. With age, our skin becomes more susceptible to wrinkles and sagging skin. Years of muscle movement ( squinting, chewing, smiling ) contribute to tissue breakdown of the skin. The tone of the muscles in our face increases. This increase in tone along with a decrease in collagen metabolism results in wrinkles. Wrinkles are made worse by smoking and sun exposure.
