Break Down the Problem

1. Identify the layers of the skin mentioned in the options.
2. Determine which of these layers contains blood vessels and which does not.

Relevant Concepts

• The skin consists of three main layers: the epidermis, dermis, and subcutaneous layer (hypodermis).
• Blood vessels are present in certain layers while absent in others.

Analysis and Detail

1. Epidermal Layer: The outermost layer of the skin. It is made up primarily of keratinized cells and does not contain blood vessels. Nutrients are received via diffusion from the dermis below.
2. Dermal Layer: The middle layer of the skin; it is rich in blood vessels, nerves, and connective tissue.
3. Subcutaneous Layer (Hypodermis): The deepest layer, which contains a mixture of fat and connective tissues, and is also vascularized.

Verify and Summarize

Upon reviewing the characteristics of each layer, it is clear that the epidermal layer is devoid of blood vessels, while both the dermis and subcutaneous layers do contain blood vessels.

Final Answer

The layer of the skin that lacks blood vessels is the epidermal layer.
