Is uneven blanching following pulsed dye laser permanent? (Photo)

My doctor used a pulsed dye laser on some areas of post-sclerotherapy blushing on my thigh (the darker areas in the picture). She said that she used one setting for those areas and another setting for the "underlying redness" as she called it. Is this uneven skin blanching surrounding the blush spots seen in the picture permanent or will my overall skin tone blend in again? Is this hypopigmentation due to lack of melanin or it just looks lighter because there are no more capillaries in the area?
