bruises are formed when something impacts the skin and capillaries in the subcutaneous layer of the skin or muscle fibers are damaged or broken. But does not puncture the skins epidermis layer so Red blood cells then leak from the capillaries and collect, as they cannot leave the body so are trapped in the layers of skin causing the red, purple or black marks under the skin that causes a new bruise. After time the blood starts to rot and take on a yellow and brown colour this is called an old bruise and the tissue underneath stats to heal. You can use a Kryolan bruise wheel or Glynn McKay bruise gels to recreate a bruise both have a great visual effect to the eye but you would pick a certain product depending on the environment that is being recreated in.
