The hands age and, over time, they begin to show wrinkles, veins and age spots. Laser treatments are used to lessen age spots.

Dermal fillers contain collagen and are injected under the skin to fill-in the wrinkles, plumps the hand, make the veins less prominent and create more youthful looking hands.
