Which practice best prevents cross-contamination between clients during eye-area services?

• A. Use disposable tools where possible and sanitize reusable tools between clients; label and date opened products.
• B. Reusing towels between clients.
• C. Storing products in direct sunlight.
• D. Sharing tools without sanitizing.

Answer: (D)

Preventing cross-contamination during eye-area services hinges on using tools that are either disposable after one client or thoroughly disinfected between clients, plus careful product handling. Disposable tools eliminate the risk of transferring microbes from one person to another because they’re discarded after each use. If reusable tools are used, they must be cleaned and disinfected with an approved method between clients to remove all potential germs. Labeling and dating opened products helps ensure you’re not using contaminated or expired items, maintaining safety for every client.

Think about why the other practices don’t fit: reusing towels between clients can transfer bacteria and oils; storing products in direct sunlight can degrade them or promote microbial growth; sharing tools without sanitizing directly facilitates cross-contamination.
