Study Demonstrates Restylane(R) Effect Lasted 18 Months in 97% of Patients With One Repeat Injection

SCOTTSDALE, Ariz., Feb. 10 (HSMN NewsFeed) -- Recent clinical data show that Restylane(R) lasted 18 months in 97% of patients with one repeat injection. Restylane(R) is the only HA filler with an 18-month FDA-approved duration claim.
