Clinical Trial Summary

The objective of this study is to determine the efficacy and safety of Restylane® Silk microinjections when used in a grid-like injection pattern for the correction of fine lines to the cheeks.

Description:

Silk for correction of mid to low cheek fine lines and wrinkles. Twenty (20) subjects will be enrolled. Each subject will receive Restylane® Silk to the entire cheeks. The defined area will be defined as the following: line extending from the upper margin of the nasal ala to the upper margin of the tragus, from the tragus to 1 cm above the mandibular angle, from 1 cm above the mandibular angle to 1 cm above the pre-jowl sulcus, and from 1 cm above the pre-jowl sulcus to the upper margin of the nasal ala. The injections will be delivered intradermally via multiple 0.02 cc microinjections distributed in a grid array pattern with 1-2 cm between each injection point (see figure 1; injections will extend 1 cm above the illustration). Following completion of injection treatment, manual massage will be applied to the full area to promote even distribution of the product. Each subject will undergo a total of three treatment sessions, one month apart, day 1, week 4, and week 8. The maximum amount of Restylane to be used per treatments session/per cheek is 1.5cc (not to exceed a total of 9 cc) per treated patient. Three-dimensional digital photography utilizing the Vectra 3D System (Canfield) will be utilized to document pre-treatment status, sites of injection, and post-treatment effect. Subjects will be followed up at 4 weeks, 8 weeks, post-treatment day 90, and day 180. Objective measures of efficacy will be me performed pre-treatment, at day 90 and 180.
