Post Profractional XC: Horizontal Lines in Skin

I had a Profractional XC Procedure - 600 microns,22%. At 3 wks post procedure,I see horizontal lines running over the area that was resurfaced. My theory: GLOBALLY, the area which was lasered does not look red. However, since redness CAN persist, can it be that the 22% on where the laser penetrated IS still red (even though it doesn't really look red) in the context of the untouched 78%? Are the lines which are giving a ridged and uneven look to the skin really just an illusion of color contrast?
