When you inject the hyaluronic acid into your patient’s dermis, the molecules hold moisture to restore volume, supporting the skin’s surface to smooth the look of wrinkles. The special blend of hyaluronic acid creates a moldable gel, so after injection, you can sculpt the gel to the desired shape. In addition to adding instant volume to skin, the hyaluronic acid stimulates collagen and elastin synthesis. This increase in collagen and elastin fibers helps restore structure and elasticity to skin for greater resilience. The dermal filler also contains lidocaine, an anesthetic that helps reduce needle pain during treatment.
