Part of a Thermi Tight neck study because as study not much info was shared with me. It's a week; Will darkness go away? (Photo)

Chin swelling,hard to the touch, I always had a dark line now I feel like is DARKER. and below that line is loose crepy skin that I thought would be attended to. Is this normal., will that darkness go away? Average time for full results? I am 47, my neck was bothering me but not severe.worried that I may look worse then before, I have to wear garment for compression at home and bed for the next 4 weeks at min I am wondering if it is actually causing the darkness b/c its uncomfortable
