Soft tissue fillers are an excellent option for nonoperative facial rejuvenation. They are injected under the skin of the face to smooth wrinkles, furrows, and lines that occur with age.
There are many different types of facial fillers, however the most common facial fillers are hyaluronic acid derivatives. Hyaluronic acid is a natural component of the human body and is abundantly found in the skin to help with dermal hydration, collagen stimulation, and tissue repair.
Sun-damage, aging, and time result in a loss of normal collagen and hyaluronic acid in the skin, which leads to decreased volume in the face and lips, ultimately resulting in wrinkles and thin lips. Injection of HA into the soft tissue is a quick, nonoperative option to fill facial volume loss, help stimulate collagen, and help to smooth the appearance of the skin giving a more youthful look.
A variety of other dermal soft tissue facial fillers exist including different derivatives and densities.
• Radiesse™ is a calcium hydroxyapatite derivative that is suspended in an aqueous gel. The carrier gel is replaced by the body’s own connective tissue (collagen) over 3-6 months. It is FDA approved for correction of moderate to severe facial wrinkles and volume loss.
• Sculptra ™ is made of poly-l-lactic acid (PLLA). It is FDA approved for moderate to deep facial wrinkles and volume restoration in patients with HIV lipoatrophy (volume loss).
The type of filler, density, and derivative used depends on the person’s facial appearance and desired outcome.
