Skin color question.

Hey yall, got a quick question.

When I use my devices, I notice a line or patch that looks a little different in color. is the new skin growing at a different color? i’d post photos but I’m not too sure i want others to see it just yet.

Recently, I’ve taken some photos for comparisons so I can do month of month visual inspections. I’m using the Mantor DS now, the newest device. It’s been stretching in new ways that I appreciate better than the TLCX.

Has anyone else had this effect ?
