Restylane is a safe and natural cosmetic dermal filler that restores volume
and fullness to the skin to correct facial wrinkles and folds, such as
nasolabial folds.

Restylane is a cosmetic dermal filler made of hyaluronic acid, a natural
substance that already exists in the human body. The hyaluronic acid in
Restylane is a crystal-clear gel called NASHA™ or Non-Animal Stabilized
Hyaluronic Acid. NASHA is completely biocompatible with human hyaluronic acid.

Restylane maintains its shape using the body's own moisture. The hyaluronic
acid in Restylane is hydrophilic or "water loving." As hyaluronic acid
gradually degrades, each molecule binds to more water and over time, the same
volume can be maintained with less hyaluronic acid. This ability of hyaluronic
acid to bind to water is what helps provide lasting results.

Unlike rooster-derived hyaluronic acids and bovine collagen products,
Restylane is free from animal proteins. This limits any risk of animal-based
disease transmissions or development of allergic reactions to animal proteins.
