A cuticle oil brush is a small, handy tool designed for the easy application of nourishing oils to the cuticle area. It typically features a sleek, pen-like body that holds the oil, with a soft, fine-bristle brush tip for precise, mess-free application. The brush ensures that the oil is evenly distributed over the cuticles, helping to hydrate and condition dry, cracked skin. Ideal for at-home use or on the go, it allows users to maintain healthy, moisturized nails and cuticles effortlessly. Some brushes may also feature a twist-up mechanism to control the flow of the oil.
