What is the main purpose of cuticle oil in nail care?

The primary purpose of cuticle oil in nail care is to hydrate and nourish the area surrounding the nails, particularly the cuticles. Cuticles are the thin layers of skin at the base of the nail that protect the new growth of the nail. When these areas are dry, they can become brittle and may even lead to hangnails or cracking. By using cuticle oil, the moisture is replenished, ensuring that the skin remains supple and healthy. Additionally, the nourishing properties of cuticle oil can help to promote better nail growth by maintaining the health of the cuticle.

In the context of other options, enhancing nail color focuses on cosmetic aspects rather than nail health, and while it’s important to have polished nails, cuticle oil does not play a role in that. Strengthening the nail plate is also critical, but this is typically achieved through other nail treatments or products that directly target the nail structure rather than the cuticle area. Lastly, removing excess polish is the function of nail polish removers, not cuticle oils, which serve a distinctly different purpose related to skin health and hydration.
