There is 3 in 1 Professional IPL ND YAG Laser RF Machine offered by us that uses light to target the tissue, while Ultherapy and radiofrequency devices use energy to heat the skin below the surface. All three result in skin tightening, however lasers and RF Machines focus energy on the surface of the skin, whereas Ultherapy targets deep below the skin. The 3 in 1 Professional IPL ND YAG Laser RF Machine is a beauty machine that uses radio waves technology to penetrate the surface of the skin.
