Using a new filler that contains hyaluronic acid and 0.3% of lidocaine (previously incorporated) reduces the pain and improves the patient’s comfort during the procedure. In vitro studies confirm that this product performs similarly to its lidocaine-free predecessors in terms of safety and efficacy. However, very few data is available on the duration of this improved product.

A study was conducted in order to determine if adding lidocaine affects the longevity of results when using hyaluronic acid as a filler.

During this study, 60 patients with severe bilateral nasolabial folds received either 24 mg / ml of hyaluronic acid with lidocaine, or a similar, lidocaine-free product. The results were monitored for 76 weeks.

The study revealed significantly better results for Hyaluronic Acid with lidocaine in terms of reducing pain and discomfort during and after the injection. Long-term follow-up of patients showed that 91% (52/57) presented no facial asymmetry after nearly a year. The researchers confirmed that lidocaine did not affect the filler’s longevity.
