Which layer of the skin is the outermost layer?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Epidermis

A Epidermis
B Subcutaneous (hypodermis) layer
C Dermis
D Muscle layer

Why this is the answer

The epidermis is the outermost layer of the skin — the part you see and touch. Beneath it lies the dermis (the deeper, living layer containing blood vessels, nerves, glands, and hair follicles), and below that the subcutaneous (hypodermis) layer of fatty tissue. The epidermis itself has no blood vessels and is composed of several sub-layers, with the tough outer stratum corneum providing protection. Knowing the basic layers of the skin and their order is foundational anatomy for the cosmetology exam.
