This is a randomized, split-face, subject-blinded, comparative study to assess and compare tissue aggregation and visualization of two Hyaluronic Acid fillers via ultrasound.~This study is designed to enroll and randomize approximately 15 subjects in a 1:1 ratio of treatment to Restylane Contour or Juvederm Voluma. All subjects are to have midface volume loss and contour deficiency.~Eligible subjects are randomized to receive treatment were injected by the Treating Investigator at Baseline.
