Which skin layers contain blood vessels?

Blood vessels are found in the dermis and in the subcutaneous layer. The epidermis has no blood vessels; its cells receive nutrients by diffusion from the deeper layers. The dermis contains a rich network of capillaries and vessels that nourish skin tissues and help with temperature regulation, while the subcutaneous layer houses larger vessels and fat storage. So, the layers that contain blood vessels are the dermis and subcutaneous.
