The Venus Viva™ fractional RF applicator has been shown in clinical studies to improve various skin conditions related to aging and alter collagen structures such as wrinkles, rhytids and scars. Beginning with the Baseline visit (Visit 1), subjects will receive a total of 3 treatments approximately 3-5 weeks apart. The left and right side of the face will be treated and assessed as independent sites, and the same applicator tip configuration will be used to treat both sides at all 3 treatment visits.

For reporting of outcomes, the higher the GAIS value, the greater the improvement (Range -3 to 3).
