Walker Plastic Surgery uses several brand name injectable fillers.
Hyaluronic Acid Fillers
Uses: Lips, Lip Line, Nasolabial Folds, Marionette Lines, Frown Lines, Crows Feet, Cheeks
Both Juvederm and Restylane are hyaluronic acid based fillers. Hyaluronic acid is a natural complex sugar found in all living organisms and creates volume and elasticity in the skin.

Juvederm smoothes wrinkles and restores volume – reversing the signs of aging. It can also be used to enhance facial features such as your lips and cheeks for added fullness and definition with a natural look. Juvederm provides correction for quite a long time (up to a year).

Restylane is a safe, natural, and well suited to plump thin lips and fill facial creases. It may also be appropriate for some surface wrinkles and concave scars. The fullness achieved from Restylane treatment may last six months or longer.
Calcium Hydroxylapatite Fillers
