How is Restylane different than other hyaluronic acid-based products?
Unlike rooster-derived hyaluronic acid-based products, Restylane® is free from animal proteins. This quality limits any risk of animal-based disease transmission or allergic reaction. Restylane® contains trace amount of gram positive bacterial proteins and should not be used by patients with a history of allergies to such material. Additionally, Restylane® has the highest concentration of hyaluronic acid available in a dermal filler.
