A colorless polish that evens out the nail plate and prevents pigments from penetrating is called a:

• A. Base coat
• B. Top coat
• C. Nail prep solution
• D. Nail bleach

Answer: (A)

The key idea is that a base coat acts as a protective primer between the nail and color. A colorless base coat smooths and evenizes the nail plate so pigments can sit evenly instead of grabbing onto uneven areas. It also creates a barrier that helps prevent pigments from staining or penetrating into the nail itself, keeping the natural nail healthier and making the color last longer. After the color is applied, a top coat is used to seal and add shine, which is different from the pre-color barrier function of the base coat. A nail prep solution prepares the nail before polish by removing oils, and a nail bleach is used for whitening or evening discoloration, not to serve as the barrier before color.
