What benefit do barrier products, like nail creams, provide?

Barrier products, such as nail creams, are designed to create a protective layer over the nails and surrounding skin. Their primary benefit is that they hold in subdermal moisture. By retaining moisture within the skin and the nail bed, these products help prevent dryness and brittleness, which can lead to issues like hangnails or weak nails. Keeping the area hydrated is essential for maintaining healthy nails and cuticles, as dry conditions can contribute to a variety of nail problems.

While some might think nail creams could speed up nail growth, add shine, or prevent nail breakage, those effects are more indirect and depend on overall nail health and care rather than being direct benefits of barrier products. The key function of locking in moisture distinguishes barrier products in their role in nail and skin care.
