As our skin ages, the dermis gradually loses its major constituents: collagen, elastin and hyaluronic acid. Collagen acts as the major support protein for our skin; elastin allows our skin to stay firm and resist wrinkles; hyaluronic acid helps to trap water and add volume and shape to our skin.
Dermal fillers are being used more and more to help reverse the changes associated with aging. Because the goal is to return the dermis to its original youthful state, dermal fillers can give a more natural appearance than surgical face lifts. Dermal fillers are being used to reduce or eliminate wrinkles, raise scar depressions, enhance lips, and replace soft-tissue volume loss.
Side effects are uncommon but can include limited allergic reactions (hypersensitivity), ulceration, reactivation of herpes infection, localized bruising.
The results can last from three months to five years, depending on the filler being used.
