What defines 'sharps' in a cosmetic and medical context?

In the context of cosmetics and medical practice, "sharps" refers specifically to objects that can cut or penetrate the skin. This includes items like needles, scalpels, and blades that are used in procedures for medical and cosmetic purposes. The designation of these items as "sharps" highlights their potential danger, as improper handling can lead to injury or infection.

Understanding the nature of sharps is crucial for safety and hygiene in both medical and cosmetic settings, as they require specific handling and disposal methods to minimize risks associated with their use. By identifying sharps correctly, practitioners can enforce regulations and guidelines that ensure both the safety of clients and the efficacy of treatments. The other options do not encompass the correct definition of "sharps"; they refer to general cosmetic tools or products that do not have the same safety implications.
