Ultrasound is used to drive lipid-soluble vitamins, moisturizers, and healing agents deep into the skin. Without the Ultrasound, these important nutrients only penetrate very superficially into the top layers of skin. Our DermaWave Ultrasound, however, allows them to penetrate the lower portions of the dermis, where they are most active and effective for nourishing and rehydrating the skin. Ultrasound energy, over time, also stimulates collagen and improves the appearance of fine lines and wrinkles.
