Co2 fractional laser technology has evolved over the years to become a significant advancement in the field of skin resurfacing. The history of fractional lasers can be traced back to the early 2000s when the concept of fractionated photothermolysis was introduced. This innovative approach revolutionized laser skin treatments by dividing the laser beam into thousands of microscopic treatment zones, leaving surrounding healthy tissue unaffected. This fractional approach allowed for more efficient healing and minimized downtime compared to traditional ablative lasers.The science behind Co2 fractional laser technology lies in its ability to deliver targeted energy to the skin in a fractionated pattern. The laser emits precise beams of light that create microscopic columns of thermal damage within the skin’s layers. This controlled thermal injury triggers the body’s natural healing response, stimulating collagen production and promoting the growth of fresh, new skin cells. As the damaged tissue is gradually replaced, the skin becomes smoother, tighter, and more youthful in appearance.The fractional nature of the laser treatment ensures that only a fraction of the skin is treated during each session, leaving surrounding tissue intact to aid in the healing process. This significantly reduces downtime and allows for faster recovery compared to traditional ablative lasers. The science behind Co2 fractional lasers has made them a popular choice for addressing various skin concerns such as wrinkles, scars, uneven texture, and pigmentation irregularities.
