Evaluation of the Filler Performance on the Nasolabial Folds of Aliaxin® EV With and Without Lidocaine 0.3%

Evaluation of the filler performance on the nasolabial folds of Aliaxin® EV with and without lidocaine 0.3%: comparison within subjects (half face method)

Comparative, randomized, mono-centre spontaneous trial, under dermatological control, that foresaw the comparison within subjects of the investigational product versus investigational product with Lidocaine 0.3% (half face method); assignation of right or left face side to the two injective treatments was choose by the Investigator according to a previously defined randomisation list.

Primary end point of the study was to evaluate the filling and bio-revitalizing activity on nasolabial folds of the product Aliaxin® EV Essential Volume, in women aged 40-65 years.

It was also aim of this study to show if the addition of Lidocaine 0.3% to the investigational product (extemporaneous mixture) could have reduced the discomfort/pain sensation perceived by the subject during the injection procedure, without altering the aesthetic performance.
