The main function of cuticle oil in nail care is to moisturize and protect the cuticles. Cuticle oil is formulated with ingredients that nourish and hydrate the skin around the nails, preventing dryness and cracking. Keeping the cuticles well-moisturized is essential for maintaining healthy nails, as dry cuticles can lead to hangnails and discomfort. Additionally, cuticle oil helps to create a protective barrier that can shield the cuticles from environmental damage and enhance overall nail appearance.

While polishing and coloring the nails are important aspects of nail care, they do not pertain to the specific function of cuticle oil. Similarly, removing nail fungus is a completely different treatment that requires antifungal products rather than moisturizing oils. Therefore, the focus of cuticle oil is firmly on hydration and protection, making it a vital component for maintaining healthy and strong nails.
