CoolTouch has developed a proven laser skin and collagen rejuvenation technique called N.I.C.E.™ (Non Invasive Collagen Enhancement) , which softens the signs of aging and promotes smoother, younger looking skin. A unique type of laser energy is applied in a series of gentle pulses over the treatment area. The CoolTouch Varia uses 1064 nm laser energy to penetrate the skin and heat the deeper skin tissue. This triggers a response in your skin, and your body begins to rebuild and replenish your own natural collagen. This leads to a tightening effect and improvement of wrinkles in most patients. The same energy can be used in a different way to target unwanted blood vessels and hair. Because the 1064 wavelength is not absorbed significantly by skin pigment, it can be also safely used to remove unwanted hair in darker skin types.
