Which of the following items must be disinfected after each use?

• A. Single-use items
• B. Tools and equipment that come into contact with skin
• C. Non-metal tools
• D. Cleansing products

Answer: (B)

The items that must be disinfected after each use are those tools and equipment that come into contact with skin. This is crucial in maintaining a hygienic environment during esthetic procedures. Since skin can harbor bacteria, viruses, and other pathogens, disinfecting these items after each use helps to prevent cross-contamination and ensures the safety of the client and the practitioner.

Single-use items do not require disinfection since they are intended for one-time use only and are disposed of afterward, making disinfection unnecessary. Non-metal tools may require specific cleaning protocols depending on the material but still fall under the broader category of tools and equipment that interact with skin. Cleansing products, typically comprised of chemicals designed to clean the skin or tools, do not need to be disinfected in the same manner as reusable tools and equipment.

Thus, ensuring that tools and equipment that come into contact with skin are disinfected after each use is a fundamental practice for infection control in esthetics.
