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.

To connect this assignment to esthetics, Hannah indicates the presence of _____ in the dermis, as well as in some skin care products, which helps to hydrate the skin.

A) Hyaluronic acid
B) Glycolic acid
C) Salicylic acid
D) Retinoic acid

Answer 1

Hyaluronic acid is present in the dermis and is used in skincare products for its moisture-retaining and skin plumping effects, which is why Hannah should include it in her skin model for the esthetics program.

Step-by-step explanation:

In constructing a three-dimensional model of the layers of skin, Hannah should indicate the presence of hyaluronic acid in the dermis, as well as in some skin care products, which helps to hydrate the skin, answering the question with option A) Hyaluronic acid.

The dermis provides strength and elasticity due to the presence of collagen and elastin fibers and contains various structures such as blood vessels, nerves, muscles, hair follicles, sweat glands, and sebaceous glands. Hyaluronic acid contributes significantly to cell proliferation and migration and is often used in esthetics due to its ability to retain moisture, leading to a plumping effect on the skin.
