Colorado Esthetician Written Practice Exam

What characteristic does a "nonporous" material have?

1. Microscopic germs

2. No pores or openings and cannot absorb liquid

3. Material with openings

4. Functions of skin tissue

The correct answer is: Microscopic germs

The correct answer is "B. No pores or openings and cannot absorb liquid." A nonporous material does not have any pores or openings which means it cannot absorb liquids. This characteristic is essential in the field of esthetics as certain tools and surfaces must be nonporous to prevent the spread of bacteria and ensure proper sanitation practices. Option A, microscopic germs, is not a defining characteristic of a nonporous material. Option C, material with openings, is the opposite of what a nonporous material is. Option D, functions of skin tissue, is unrelated to the definition of a nonporous material.
