What is the purpose of the cuticle?

• A. To protect the matrix from bacteria and damage
• B. To help polish adhere
• C. To color the nail plate
• D. To nourish the surrounding skin

Answer: (A)

The cuticle’s primary job is to protect the nail matrix, the area where new nail cells form, by acting as a barrier against bacteria, fungi, and moisture. Keeping this barrier intact helps prevent infections and damage to the growing nail. It doesn’t govern polish adhesion, coloring of the nail plate, or nourish the surrounding skin—those effects come from surface interactions, pigments, or moisturizers applied to the skin. In practice, technicians groom the cuticle to maintain the protective seal while avoiding cutting live tissue.
