What is a crucial step Yelda must take to ensure effective sterilization of tools after a lash extension application?

To ensure effective sterilization of tools after a lash extension application, it is essential to clean the tools properly before placing them in the sterilizer. This step is crucial because any organic matter, such as adhesive residue or skin cells, can interfere with the sterilization process. Thorough cleaning removes visible debris and microorganisms, allowing for the sterilization method to effectively eliminate any remaining pathogens.

Utilizing a sterilizer without first cleaning the tools may not achieve the desired level of sanitation, as contaminants can shield bacteria from the sterilizing agent. Hence, proper cleaning is the foundation for effective sterilization, ensuring tools are safe for future use and minimizing the risk of infection.
