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.*
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.
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 Safety Information
Restylane® is indicated for treatment of moderate to severe facial wrinkles and folds, such as nasolabial folds. After your treatment, you might have some redness or swelling. This will normally last less than seven days. Avoid excessive sun and UV lamp exposure, and extreme cold weather until any redness or swelling disappear. If you are pregnant, breastfeeding, have severe allergies, or under 18, you shouldn’t use Restylane. Ask your physician if Restylane is right for you.
