Fast Fit uses a proven, patent-pending system to target stubborn fat. It reduces troubled areas like the stomach, hips, thighs, and arms. We do this by opening the pores on the fat cells causing the release of fatty acids to be metabolized through natural bodily functions. The light stimulates fibroblasts, strengthening the collagen and elastin fibers to tighten and tone the skin. This promotes the reduction of sagginess, rolls, or crepey skin.
