Which tissue layer is the subcuticular running stitch placed in?

• A. Dermis
• B. Epidermis
• C. Subcutaneous
• D. Muscle

Answer: (A)

The subcuticular running stitch sits in the dermis, the layer just beneath the epidermis. This depth provides the right balance of strength and tissue support to bring the wound edges together with a clean, hidden scar. Placing the stitch in the epidermis would lack structural holding power and tend to track or scar, while sitting in the subcutaneous tissue would be too deep and risk dimpling or a visible incision line. Muscular tissue is far deeper and not part of skin closure, so it wouldn’t properly approximate the skin edges.
