Q: How is Restylane different than other
hyaluronic acid-based products?

A Unlike rooster-derived hyaluronic acidbased
products, Restylane is free from animal
proteins. This quality limits any risk of
animal-based disease transmission or allergic
reaction. Restylane contains trace amounts
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.
