The redness and capillaries of Rosacea are best treated with a vascular specific laser or light source. The most effective laser, and gold standard treatment for this type of Rosacea is the Pulsed Dye Laser, with the VBeam laser being far and away the most commonly utilized. Other options include the 532-KTP lasers and Intense Pulsed Light (IPL) devices, but I generally find these less effective with more potential for side effects.
Pixel Lasers treatments are used for resurfacing-- improvement of such things as lines, wrinkles, textures and scarring. They are generally safe in all lighter skin types and most Asian, Hispanic or Middle Eastern skin. I personally would not treat darker skin types, such as African-American skin (Fitzpatrick V or VI)
