The newly developed RF-Excited CO2 fractional laser fires a laser beam through an RF CO2 tube split into microscopic beams, producing a tinier dot than a general CO2 laser (glass tube). The treatment tip can vaporize the outmost layers of the skin across a large surface by creating thousands of tiny, microscopic laser wounds, spaced in an even pattern across the skin. Still, leaving areas of healthy, untreated skin between them, the lower collagen layer of the dermis is stimulated to renew and repair. Therefore, the laser’s heat only passes deeply through the factional damaged area, and the surface of the skin now contains only microscopic surface wounds, instead of a large, red, oozing burn. During the skin self-resurfacing, a great amount of collagen is produced for skin rejuvenation, after some recovery, the newly generated skin is remarkably smoother, and healthier.
