Restylane is the top selling injectable dermal filler in the world. Like Juvederm, Restylane is also a hyaluronic acid, designed to restore volume and smooth facial wrinkles. Restylane uses the body’s own moisture to sustain its shape at the injection site. While hyaluronic acid gradually degrades, each Restylane molecule binds with water within the body, thus increasing the volume for enduring results. Restylane is void of any animal proteins, and allergy testing is not required prior to use, making it a safer, more viable option as a filler to a wider range of patients.
