Which are the two main layers of the skin?

• A. Dermis and subcutaneous
• B. Epidermis and dermis
• C. Epidermis and subcutaneous
• D. Stratum corneum and epidermis

Answer: (B)

Skin really has two main layers: the epidermis and the dermis. The epidermis is the outer protective barrier, made of keratinocytes, and it has no blood vessels. The dermis sits beneath and is thicker, containing connective tissue, collagen and elastin, blood vessels, nerves, hair follicles, and glands, which gives skin its strength and elasticity. The subcutaneous layer (hypodermis) lies below the dermis and isn’t considered part of the skin proper; it’s mainly fat and connective tissue. The stratum corneum is just the outermost portion of the epidermis, not a separate main layer. Knowing these layers helps in barbering for understanding how products and procedures interact with skin and where vulnerability to irritation or injury may lie.
