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.

These data were generated in a controlled, randomized, evaluator-blinded study that assessed the safety and effectiveness of two different retreatment schedules, 4.5 months or 9 months, after initial treatment of nasolabial folds (NLF). Patients were evaluated using the Wrinkle Severity Rating Scale (WSRS), a five-point scale to measure visual severity of wrinkles where five is the most severe rating (extreme). 92% of patients were naive to dermal fillers so had no residual effects from earlier treatment.

Key findings from the study include:

-- At 18 months, 97% of patients continued to show improvement in NLF correction with one repeat injection

-- Correction with Restylane(R) lasted for 18 months, regardless of retreatment schedule

-- At 18 months, patients still had a 1.7 grade improvement in WSRS over baseline

-- Adverse events were primarily swelling (24%) and bruising (19%); none were serious.
