Microdermabrasion machines utilize which of the following materials?

1. Salt

2. Glass beads

3. Topical enzymes

4. Steel particles

The correct answer is: Salt

Microdermabrasion machines typically utilize materials that can effectively exfoliate the outer layer of the skin, promoting cell turnover and improving skin texture. In this context, salt is commonly used in certain types of microdermabrasion treatments because it can provide a gentle abrasive action while also having therapeutic benefits for the skin, such as antibacterial properties and moisture retention. While other materials like glass beads, topical enzymes, and steel particles are used in different exfoliation techniques or treatments, they do not represent the primary materials used in microdermabrasion procedures. Glass beads, for instance, might be used in some contexts, but they can be harsher and are not as widely recognized for gentleness on sensitive skin compared to salt. Topical enzymes serve a different purpose and are intended for chemical exfoliation rather than mechanical exfoliation. Steel particles, while potentially effective for abrasion, are not typically utilized in practice due to safety and skin irritation concerns. Understanding these materials and their respective applications helps clarify why salt is an appropriate answer for the specific context of microdermabrasion machines.
