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 tie this project in with her esthetic training, Hannah includes a discussion of tyrosinase inhibitors, which can reduce hyperpigmentation by _____.

A) Increasing melanin production
B) Inhibiting collagen synthesis
C) Blocking sebum production
D) Suppressing tyrosinase activity

Answer 1

Tyrosinase inhibitors play a role in esthetics by D) suppressing tyrosinase activity, which in turn reduces hyperpigmentation by reducing melanin production from melanocytes in the skin.

Step-by-step explanation:

Tyrosinase inhibitors play a role in the field of esthetics by reducing hyperpigmentation. They achieve this effect by D) Suppressing tyrosinase activity, which is a key enzyme involved in the production of melanin by melanocytes.

Melanocytes are located in the stratum basale of the epidermis and transfer melanin to keratinocytes through melanosomes.

The hypodermis and deep fascia are deeper layers of the skin that primarily consist of connective tissue and help insulate the body and protect underlying muscles and organs.

Keratinocytes, which form the bulk of the epidermis, are generated from stem cells in the stratum basale and undergo a life cycle where they differentiate, produce keratin, and eventually die and are shed from the skin's surface through a process known as desquamation.

Understanding the roles and life cycle of these skin cells is crucial in esthetic practices that focus on skin health and appearance.
