The dermis is the layer of skin that contains the most blood vessels. This layer is situated beneath the epidermis and is responsible for providing nutrients to the skin through these blood vessels. The dermis is rich in connective tissue and features various structures, including hair follicles, sweat glands, and sebaceous glands, all of which rely on the blood supply for their function and survival.

The abundance of blood vessels in the dermis plays a critical role in thermoregulation and in the inflammatory response to injury, ensuring that necessary immune cells can reach affected areas. The epidermis, being the outermost layer, does not possess blood vessels; instead, it relies on the dermis for oxygen and nutrient exchange. The subcutaneous tissue, while it does contain blood vessels, primarily serves as an insulating layer and energy reserve rather than the site with the highest concentration of blood vessels related to skin function. The stratum corneum is the outermost layer of the epidermis and is composed mainly of dead skin cells that are not involved in blood supply.
