Which layer is the deepest of the three main skin strata?

• A. Epidermis
• B. Dermis
• C. Hypodermis
• D. Stratum corneum

Answer: (C)

Understanding skin layers and where pigment sits helps explain this. From the surface down, the main layers are the epidermis, then the dermis, and beneath them lies the hypodermis (subcutaneous tissue), which is mostly fat and connective tissue that anchors the skin and cushions underlying structures. The deepest of these is the hypodermis, because it lies beneath the dermis. The outermost part of the epidermis includes the stratum corneum, which is not the deepest layer. In permanent makeup, pigment is deposited in the dermis, not the hypodermis, to achieve lasting color and proper healing; going into the hypodermis can affect color stability and healing.
