Rowe says communicable diseases can be transmitted through contaminated makeup and suggests that both makeup counters and spas supply Q-tips for client use, and spas and counters should clean the makeup dispenser between users. He says that by cleaning the dispenser in view of the next user will make the client feel comfortable.

Lolis suggests that spas follow the International Spa Association (ISPA) guidelines, which say the following: "Products, equipment and instruments used in spa services and treatments are cleaned, disinfected, stored and used in compliance with the manufacturer’s instructions and guidelines. Staff is trained on how to handle products and provide first aid if needed." Lolis also suggests that surfaces are wiped down and instruments sterilized.

"Keeping products closed when not used is a good idea," says Lolis. "Testers are a breeding ground for bacteria so again, a formula of wipe-test-wipe again must be encouraged. When working with a makeup artist be sure to bring your own brushes or make certain the makeup artists sterilized brushes and cleaned them thoroughly."
