A base coat serves several crucial functions in nail applications, with one of its primary purposes being to prevent staining and strengthen the nail. When applying colored polish, particularly darker shades, the base coat acts as a protective barrier that stops pigments in the nail polish from soaking into the natural nail. This helps to prevent discoloration and maintains the integrity of the nail bed.

Additionally, some base coats are formulated with strengthening agents, providing extra support to the nails and helping to reduce the likelihood of chips and breaks. By reinforcing the nails, a base coat contributes to overall nail health, which is particularly important for individuals who frequently use nail polish.

While various other purposes related to nail applications exist, such as enhancing color vibrancy or speeding up drying time, the core function of a base coat encompasses protection against staining and offering strength to the nails.
