Which of the following products is intended to absorb into the nail plate and surrounding skin?

Nail oils are specifically formulated to be absorbed into the nail plate and the surrounding skin. They contain a blend of moisturizing ingredients that not only hydrate the cuticles and skin but also penetrate the nail plate to provide nourishment. This absorption helps maintain nail health, flexibility, and overall appearance.

In contrast, nail polish is primarily designed to coat the surface of the nail, creating a protective and decorative layer. Nail hardeners, on the other hand, are used to strengthen the nails but do not absorb into the nail plate in the same way oils do. Nail adhesives are meant for bonding artificial nails or tips to the natural nail and remain on the surface, not penetrating into the nail structure or surrounding skin. Thus, nail oils stand out as the product that is specifically intended for absorption.
