The layer(s) of the skin containing blood vessels is/are

Blood vessels run through the deeper skin layers, not the outermost surface. The epidermis has no blood supply of its own and relies on nutrients diffusing from vessels in the layers below. The dermis hosts a rich network of capillaries, arteries, and veins that supply skin cells, support healing, and help regulate temperature. Beneath the dermis, the subcutaneous layer (hypodermis) contains larger vessels and fat that supply the dermis and provide insulation. Because both the dermis and the subcutaneous layer contain blood vessels, those are the layers that have the blood supply.
