What does the term nonporous refer to in materials?

1. Materials that absorb liquids easily

2. Materials without pores or openings that cannot absorb liquids

3. Materials that are lightweight and flexible

4. Materials that are often used in furniture

The correct answer is: Materials without pores or openings that cannot absorb liquids

The term nonporous refers to materials that do not have pores or openings, which means they cannot absorb liquids. This is an important characteristic in esthetics, especially when considering the use of tools, products, or surfaces that must remain clean and hygienic. Nonporous materials are often preferred in salons and spas because they are easier to sanitize, reducing the risk of bacterial growth and contamination. In contrast, porous materials have tiny openings that can trap liquids and debris, which can compromise hygiene standards. While some materials may be lightweight and flexible or commonly used in furniture, these attributes do not define nonporosity. Thus, understanding the significance of nonporous materials is crucial for ensuring a safe and effective practice in esthetics.
