Fractional CO2 versus Profractional Laser Resurfactional Resurfacing in Sacramento Jul 1, 2009 CO2 fractional lasers utilize CO2 which has a higher wavelength of light in the Infra red spectrum. Like Erbium it also uses water as a chromophore. However it is not as specific so the thermal relaxation time isn’t reached as quickly and the tissues surrounding… View more
