Can pulsed dye laser (for example vbeam) eliminate completely the persistent redness if a do a lot of sesions like 8?

I've seen a lor of pictures of before and after treatments of rosacea, in some cases the redness seems completely gone but in others there is some redness that remains (usually where the redness was worst to begin with). I wonder if that remain redness can be eliminated by doing more sesion of the laser or if always is gonna be some redness left. Can the areas affected by rosacea look exactly that the skin tone of your face that is not affected after laser? Is there always going to be some redness left even if a do for example 8 sesions of vbeam in order to try to eliminate de redness completely? Thanks a lot.
