i had 1 laser(Co2 i believe it was)treatment on my nose for a small broken blood vessel.after the procedure the skin felt and looked burned almost like a cigarette burn and a scab formed.it took 2 weeks for the wound to heal and now the surface of the skin looks good but the whole area where she used the laser is pink/red.will this redness go away? it's been 3 weeks since the procedure.
