What is one of the key topics covered in sanitation for the New York State Aura exam?

The focus on the proper cleaning and disinfection of tools and equipment is crucial in sanitation protocols, particularly in a professional setting such as a salon or spa. This topic ensures that all instruments and surfaces are free of harmful microorganisms that can cause infections or illnesses. The importance is underscored by the fact that improper sanitation can lead to health risks for clients and practitioners alike. Training in sanitation procedures emphasizes not only the cleaning process but also the importance of adhering to health and safety regulations in the beauty industry, ensuring that professionals maintain a high standard of hygiene.

The other options, while relevant to the practice of esthetics or beauty services, do not pertain directly to the sanitation guidelines necessary for the exam. Application of makeup, skin treatments, business ethics, and skincare products, while important to the overall practice, do not specifically address the critical need for maintaining a clean and safe working environment through proper sanitation measures.
