Which of the following items is most recommended for applying before bedtime to maintain nail health?

Applying oils, creams, or lotion before bedtime is most recommended for maintaining nail health because these products provide essential moisture and nourishment to both the nails and the surrounding skin. Unlike Vaseline, which is an occlusive agent that can trap moisture but doesn't provide nutrients, or water, which evaporates quickly and doesn’t have moisturizing properties, oils and creams are formulated with ingredients specifically aimed at enhancing hydration and strength in nails. Nail polish, on the other hand, serves mostly as a cosmetic feature rather than a functional treatment, as it can create a barrier that prevents nails from absorbing moisture. Therefore, using a combination of oils or creams before bed can improve flexibility, prevent brittleness, and maintain overall nail health effectively.
