The ThermaCool system uses a sophisticated treatment tip called ThermaTip™, which delivers a controlled amount of RF energy. With each touch to the skin, the ThermaTip device uniformly heats a large volume of collagen in the deeper layers of the skin and its underlying tissue while simultaneously protecting the outer layer of the skin with cooling. This deep uniform heating action causes deep structures in your skin to immediately tighten. Over time, new and remodeled collagen is produced to further tighten skin, resulting in healthier, smoother skin and a more youthful appearance..
