Red dots

DD

So I got burned in January and it’s now healed. But for some reason these little red dots keep popping up and sometimes itch. Does anyone know what it’s from? I moisturize, do I just need to do it more? Could it be the lotion? I know to stay away from alcohol based lotions. Idk lol I’m not freaked out or anything but it’s just kinda irritating.

It’s on the inside of the top of my arm.
