Which of the following procedures is NOT part of infection-control procedures?

The answer focuses on why cosmetic application techniques do not fall under the umbrella of infection-control procedures. Infection control is primarily concerned with preventing the spread of pathogens and ensuring a safe environment for both practitioners and clients.

Hand washing is a fundamental practice that helps to eliminate contaminants from the skin, thus reducing the risk of infection. The use of protective equipment, like gloves and masks, serves to create a barrier that protects individuals from exposure to potentially infectious materials. Disinfection of skin care implements ensures that tools used during treatments are free from harmful microorganisms that could be transmitted between clients.

In contrast, cosmetic application techniques involve the various methods and skills used to apply makeup, skincare products, and other cosmetics. While these techniques are certainly important for estheticians to master for effective service delivery, they do not directly relate to infection control measures. Their primary focus is on aesthetic results rather than on preventing the transmission of infections. Therefore, this distinction is why cosmetic application techniques are not considered part of infection-control procedures.
