What is the purpose of using a base coat in nail care?

The purpose of using a base coat in nail care is to protect the natural nail. A base coat serves as a barrier between the nail and the colored polish, helping to prevent staining and damage to the nail plate that can be caused by pigments in the polish. Additionally, the base coat can help the polish adhere better to the nail, which can prolong the wear of the manicure. This protective layer is essential for maintaining the health of the natural nails, especially when frequently applying colored nail products. By creating this foundation, the base coat promotes overall nail health and aesthetic appeal.
