What Are Hyaluronic Acid Fillers?

Hyaluronic acid fillers are injectable gels made from cross-linked hyaluronic acid, a naturally occurring sugar that attracts and retains water.

They are commonly used for:

• Lip enhancement
• Chin augmentation
• Nose contouring
• Cheek enhancement
• Jawline definition
• Under-eye hollows
• Temple restoration
• Nasolabial folds
• Marionette lines
• Facial rejuvenation
• Hand rejuvenation

Because hyaluronic acid is gradually broken down by the body, treatment results are temporary and maintenance sessions are typically recommended.

How Hyaluronic Acid Fillers Work

Hyaluronic acid binds large amounts of water, helping restore volume and improve facial contours.

Treatment may help:

• Restore lost facial volume
• Smooth facial folds
• Improve facial symmetry
• Enhance facial contours
• Improve skin hydration
• Create softer facial transitions
• Produce natural-looking facial rejuvenation

Different filler products vary in firmness, elasticity, cohesivity, and longevity depending on the treatment area.
