Is It Normal for Facial Telangiectasia to Get Darker After KTP Laser Treatment?

I had KTP laser treatment (Iridex Diolite long pulsed - 532nm) for facial veins on my cheeks and nose, done 4 days ago by a reputable dermatologist in a clinical setting. I had some thin scabbing/crusting along the veins that were treated that is starting to fall off, but the veins underneath appear much darker than they were initially. Is this normal? Will they disappear? Can I do anyting to speed up the process? Many thanks
