Question

As a student in an esthetic program, Hannah is tasked with building a three-dimensional model of the layers of the skin. Her model must include captions describing each skin layer and connect skin histology and physiology to esthetics. Hannah visits a craft store to purchase supplies from which she will construct her model.

First, Hannah focuses on ways to model the _____, the layer of skin upon which estheticians are licensed to work.

a) Dermis
b) Epidermis
c) Hypodermis
d) Stratum corneum

Answer 1

The layer of skin upon which estheticians are licensed to work is the epidermis. It is the outermost layer of the skin, acts as a barrier, and does not have a blood supply. The dermis is located below the epidermis and contains various structures such as blood vessels and sweat glands.

Step-by-step explanation:

The layer of skin upon which estheticians are licensed to work is the epidermis. The epidermis is the outermost layer of the skin and acts as a barrier to water and pathogens. It is composed of keratin-filled cells and does not have a blood supply. Below the epidermis is the dermis, which contains blood vessels, sweat glands, and hair follicles. The innermost layer is the subcutaneous tissue, or hypodermis, which consists of connective tissue and fatty tissues.
