What is the primary function of nail cream?

The primary function of nail cream is to seal the surface and retain moisture. Nail creams are formulated to create a barrier that helps to hydrate the nails and surrounding skin. This moisture retention is crucial in preventing the nails from becoming dry and brittle, which can lead to breakage and other nail issues. By sealing in moisture, nail creams contribute to the overall health and appearance of both the nails and the cuticles.

While options such as hardening the nails, softening cuticles, and cleansing the nails may address specific concerns, they are not the main purpose of nail cream. Nail creams are more focused on hydration and protection rather than altering the hardness of the nails or performing cleansing actions.
