What must be properly disinfected before use according to cosmetology standards?

The correct answer is that sharpeners must be properly disinfected before use according to cosmetology standards. This is important because sharpeners are used to prepare cosmetic pencils for application, and they can easily collect bacteria and contaminants from the pencils. Regular disinfection helps to prevent the spread of infection and skin-related issues.

While pencil cosmetics may seem like they need attention, they themselves are not the direct item that is in contact with the skin. Cosmetic brushes and beauty tools also require proper sanitation, but the question specifically highlights sharpeners as a pivotal item in maintaining hygiene standards in a salon or cosmetic setting. Properly disinfecting sharpeners ensures that all tools used in application are safe and sanitary for clients.
