Liplase lip augmentation Fuller, Tighter, Smoother Lips Without Injections We offer a new way to enhance the size and shape of your lips without injections. Here at Renew Stem Cell & Laser, we use our Fotona laser to naturally tighten, smooth, and plump your lips using heat to stimulate collagen production. This treatment treats the lips and surrounding skin as well as the inner lips to stimulate the collagen from both sides, which creates fuller, smoother, tighter lips and a more youthful appearance.
