The youthful face has a large volume of collagen, hyaluronic acid, and elastin. As we age, all three begin to break down at an elevated rate. As this occurs, we often notice that we lose fullness and integrity within the skin of the face. This may result in a "hollow" appearance in areas of the face or deepening of wrinkles.
Fillers are hyaluronic acid used to plump wrinkles throughout the face. Fillers are composed of a laboratory-created hyaluronic acid, similar to the natural hyaluronic acid present in youthful skin. When injected into the areas of hollowness or into deep lines of the face, it has an immediate effect on the fullness and plumpness in areas of injection.
The lab-created hyaluronic acid in these products has been modified slightly to last longer than your own hyaluronic acid. Hyaluronic acid is hydrophilic, which means it’s “water loving,” and as such, it attracts many times its own weight in water. Even as the hyaluronic acid begins to disappear, each molecule attaches to more water, which means it will maintain its volume and effect for between four and six months. Injections of Restylane can be expected to have lasting effects for 4 to 6 months. Juvederm can be expected to have lasting effects for up to 12 months.
Common areas for filler injection include:
nasolabial folds (the lines that run diagonally from the nose to the mouth)
glabellar lines (between the eyebrows)
wrinkles around the lips and around the eyes.
