Restylane

Restylane, a nonanimal stabilized hyaluronic acid (NASHA), was the first hyaluronic acid filler to receive FDA approval in 2003.

I use a lot of Restylane and Juvederm on my patients, as they are thicker than previous fillers, last longer, are more natural and mold easily. Thick lines and wrinkles require a thicker substance to build back the collages or fat in our faces that we lose when we age.

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 has a highly favorable safety profile. It is composed of non-animal stabilized hyaluronic acid. Hyaluronic acid is a substance found naturally in the human body. Restylane is fully biocompatible. There is limited risk of animal-based disease transmission or development of allergic reactions to animal proteins. No allergy testing is required before use. 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.

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 long-lasting results.
