What is one of the primary benefits of applying a base coat before nail polish?

Applying a base coat before nail polish serves several important functions, and one of the primary benefits is that it protects the nail plate from staining. Nail polishes, especially those that are highly pigmented, can sometimes leave a residue or tint on the nails if applied directly. The base coat acts as a barrier, preventing the pigment from penetrating the nail surface and minimizing the risk of discoloration.

While it is true that base coats can contribute to the longevity of polish, preventing chipping or promoting quicker drying times are secondary benefits and not their main purpose. Furthermore, base coats do not have any direct effect on increasing nail growth, as growth is primarily determined by biological factors. Therefore, the role of the base coat in protecting the nail plate from staining stands out as a significant and essential advantage before applying nail polish.
