9 months pot op Airsculpt, liposuction of my abdomen (front and back). Last night I noticed some dark lines by incisions

Last night I noticed some dark colored lines from my incisions (right side) only. They are pretty significant, and you can clearly see them. I thought they were veins? Then I thought maybe stretch marks? I don't see them on the left side. I'm 9 months post op and have been loving my results up until now.
