Why is RevitaLift Collagen Filler Lip Duo right for me? With time, collagen and moisture levels diminish, resulting in thinner lips, wrinkles around the mouth, and less defined lip-line. The Innovation: Inspired by dermatological lip plumping and contouring procedures (Results not equal to medical procedures), RevitaLift Collagen Filler Duo is a 2-step contouring treatment enriched with collagen biospheres and hyaluronic micro-spheres. 2-Step Lip Contouring Action: Step 1: Lip Line Filling Cream: Lip Line Filling Cream enriched with collagen biospheres instantly helps redefine the lip-line, while dramatically reducing lipstick feathering. Step 2: Lip Plumping Serum: Lip Plumping Serum with hyaluronic micro-spheres boosts lips' natural hydration for a gentle lip plumping effect leaving lips looking fuller and smoother - perfect for lipstick application.
