I have this bit of skin discoloration around my neck.. As far as I know I am (not) allergic to anything. I havent had any diet changes and I dont have anymore stress than normal. The bit of discolored skin seems a tad less smooth, almost dry compared to the rest of my skin. It doesnt itch, sting or cause any kind of discomfort. I didn't even know it was there until I noticed it in the mirror. Now that I did notice it i'm not sure how long it's even been there. Any ideas what this could be? How I can get rid of it?
