Last month I discovered these red dots on my arms and one on my chest. They do not itch and are not in groups like a rash. I think they are red moles, or cherry angiomas since I am nearing 30 and they look like none of scary stuff on my 2 hour skin research journey.
Here is a picture:
The red dot is in the center of the image. From my eyes it looks like someone poked me with a red pin, but I think the camera caught more details.
