Safety and efficacy of a cohesive polydensified matrix hyaluronic acid for the correction of infraorbital hollow: an observational study with results at 40 weeks.

Background: Utilizing a soft-tissue filler that is more fluid and less resistant to deformation may be advantageous for correction of infraorbital hollows.

Objective: The objective of this study was to determine the safety and efficacy of the latest hyaluronic acid filler, created with a cohesive polydensified matrix, with a low elasticity and viscosity, for infraorbital hollows correction.

Methods And Materials: Subjects (49) with at least a grade 2 Merz infraorbital hollow scale in the Validated Assessment Scales for the mid face (0-4) of the right and/or left side were photographed and treated at baseline, and with a touch up treatment after 2 weeks if necessary.
