What is the primary purpose of using a base coat in a manicure?

The primary purpose of using a base coat in a manicure is to protect the natural nail from staining and to provide a smooth surface for the polish. A base coat serves as a barrier between the nail and the colored polish. Some colored polishes contain pigments that can stain the nail bed; the base coat helps to prevent this discoloration. Additionally, the smooth surface created by the base coat ensures that the colored polish adheres better and applies more evenly, leading to a more polished and professional-looking manicure. This foundational step is essential for achieving optimal results and maintaining the health of the natural nails.
