Applying petroleum jelly, such as Vaseline, to your fingernails and surrounding cuticles is exceptionally beneficial for maintaining hand and nail health. Vaseline acts as a powerful occlusive barrier that seals in natural hydration, preventing dry, brittle nail plates from splitting and protecting painful, peeling cuticles. Regular nightly application shields the delicate skin matrix around the nail bed from harsh weather, frequent hand washing, and chemical irritation encountered during daily tasks.
