Formal language:

Acute abrasions are produced when the granular and keratinized skin cells are abruptly removed from the underlying dermis or “true skin.” Trauma denudes the epidermis, thereby exposing the more substantive lower papillary and reticular dermis, and punctate bleeding occurs from the severed arterioles of the dermal papillae. These pinpoint areas of bleeding within a larger patch of tissue exudate contribute to what is often clinically referred to as a “raspberry” or “strawberry.”
