What are tiny little red blood blisters on your torso from?

Hemangiomas. All those little red bumps or "blisters" on your body are called hemangiomas. These are hereditary growths. If you were to cut them out and look at them under a microscope, you would see thousands of little blood vessels. Hemangiomas are completely benign growths that never turn bad. I treat them with different lasers and they respond beautifully.
