What is the primary purpose of a base coat in nail care?

The primary purpose of a base coat in nail care is to protect the nail plate. It serves as a protective barrier between the natural nail and the nail polish, preventing potential staining from colored polishes that can occur over time. The base coat also helps to improve the adherence of the nail polish, ensuring a longer-lasting manicure. Additionally, some base coats are formulated with strengthening ingredients that can help to reinforce weak or brittle nails.

While some might consider that a base coat can add color or shine, its fundamental role is protection and foundation for the polish to adhere properly. Different base coats can cater to specific nail needs, but protecting the nail from chipping and staining remains the primary function, making it essential in any nail care regimen.
