A gel-based filler consists hyaluronic acid, a natural constituent of the dermis, the second layer of skin. Naturally occurring hyaluronic acid lends structure, firmness, and volume to the skin. Although abundant in youth, the passage of time and exposure to environmental factors such as ultraviolet light exposure decreases the presence of hyaluronic acid in the skin. Hyaluronic acid attracts water to the area of placement, “plumping” the treated areas and decreasing the presence of facial lines, wrinkles, and folds.

Hyaluronic acids have now become the gold standard of fillers, meaning they set the bar for which new fillers must be compared in the FDA approval process. Fillers last for approximately 6 to 12 months. The product undergoes isovolumic degradation, meaning that as filler is broken down in the skin, the hyaluronic acid particles attract more water, allowing consistent wrinkle correction over the life of the filler. Mild swelling and bruising are the most likely side effects following injection. These side effects can be minimized with proper injection technique.
