Nail fillers or nail putty are cosmetic products used to smooth out and fill minor depressions in the nails, providing an even surface for nail cosmetics.
A nail product used to smooth out and fill in minor depressions in a client's nails is often referred to as a nail filler or nail putty. Such products are designed to improve the appearance of the nail plate, which is the external, visible part of the nail. By doing so, they create a uniform surface that may help in the application of nail polish or other treatments.
The cuticle and the nail fold play important roles in protecting the nail edge but are not directly involved in filling depressions of the nail plate. The nail matrix, although essential for nail growth, is not related to the function of a nail filler product.
Nail fillers are useful for creating an even surface on the nail plate, aiding in personal grooming and cosmetics application. They help to conceal flaws and ensure a more polished final appearance.
