Non-porous tools should primarily be considered for which characteristic?

Non-porous tools are primarily characterized by their ability to be reused safely due to their smooth, non-absorbent surfaces. This quality makes them ideal for practices requiring strict hygiene standards, as they can be effectively cleaned and disinfected between uses, thereby preventing the risk of cross-contamination. The durability and resistance of non-porous materials ensure that they maintain their integrity after multiple applications, making them suitable for repeated use in a variety of cosmetology services.

While non-porous tools might be used in single applications or considered for disposal in certain contexts, their defining feature is their reusable nature. This characteristic allows cosmetologists to employ them repeatedly while maintaining a high standard of sanitation.
