2nd VBeam + Kenalog shot to reduce red hypertrophic scar, but appearance of white spots? (Photo)

Hi, I got my second VBeam _ Kenalog scar treatment for my hypertrophic scar after BA (the BA was a year ago). This time after my session, it has been more than 4 weeks and there are still some white spots appearing that wasn't there after my first VBeam + Kenalog treatment. Can someone let me know if I should be worried and what are exactly the white spots ? Thank you so much !
