know this is really late, and you might have cured it already, but I just couldn't help but share this. I had the exact same problem. It was there for 6 months at least. At first it was small and unnoticeable, but later it started to spread across my whole neck, to a point where I had to pair every outfit with a scarf. I was going to meet with a dermatologist, so I went to my mom to see if she could reference me to any. My mom asked me if I'd ried cleaning it. I had, but I'd just wiped it. She told me to scratch at it with my fingernail, and to my great surprise, it worked! Just rub on some soap, and scrape away at it with your fingernail. I'm so glad I went to my mom first. The marks were there because I didn't clean my neck enough. Whenever I take a shower now, I make sure to get my neck! Hope it helps!View Thread
