Washington Esthetician State Board Practice Exam

In the context of esthetics, which type of technique serves as a delivery system?

1. Physical

2. Chemical

3. Mechanical

4. Biological

The correct answer is: Chemical

The correct answer pertains to chemical techniques serving as a delivery system in esthetics. Chemical techniques, such as the use of topical solutions and compounds, utilize active ingredients that penetrate the skin and deliver various benefits, including hydration, exfoliation, or treatment of specific skin issues. This delivery system is essential for achieving desired skin results, as the effectiveness of a treatment often depends on how well these ingredients can be absorbed by the skin. In contrast, physical techniques primarily involve methods like massage or exfoliation that do not incorporate chemical agents to deliver results. Mechanical techniques focus on tools or devices used in treatments but lack the chemical interaction that provides a delivery system. Biological techniques do involve living organisms or biological processes but are not typically classified as a main delivery system in esthetic practices. Overall, chemical techniques are fundamental in utilizing the science of skin care to provide effective treatment outcomes.
