I get deep, red lines, irritation every place a waistband, bra, grippers etc touches me. It takes hours for it to go away. Even my socks cause a slight line. I just live with it. It's allergy related, gets worse when I'm under stress, or having a real allergy thing. It seems to get more "reactive" at times and I have no idea why. No allergist has ever figured it out. I can just brush my hand on my skin or normally scratch an itch and I will have marks for a day.
