The primary function of cuticle oil is to moisturize and nourish the cuticles. Cuticle oil is specifically formulated with various oils and essential nutrients that help keep the cuticle area hydrated. This is important because well-nourished cuticles promote healthy nail growth and protect the area around the nails from damage and infection.

When cuticles are dry or damaged, they can become rough, create hangnails, or even lead to more serious nail problems. Regular application of cuticle oil helps to maintain softness and elasticity in the skin around the nails, which is essential for overall nail health.

While cuticle oil may have benefits that could indirectly support the other functions listed, such as enhancing the appearance of a manicure by providing a healthy, shiny look, its principal purpose is clearly focused on moisturizing and nourishing the cuticles. This enhances their health rather than serving as a method to strengthen nails or act as a protective layer like a top coat would.
