I remember I noticed the same once, Of course I freaked out too, haha. If you scratch, that`s how your skin looks like after. I was freaking out because I had(still have) all over these tiny red spots under my skin. I even told to a doctor about it, and he just laughed at me. lol. He said everybody has those spots, and that`s normal.
relax. Does not look bad at all.
