Artificial nail extensions are nail coatings applied over natural nails to provide a protective coating for the nail plate and may extend beyond the free edge of the natural nail to add length. There are three categories of artificial nail extension products: liquid/powder systems, light-cured systems, and wraps. These systems should be applied by properly trained nail professionals who know how to prepare the nail plate, maintain the artificial nail, and understand proper and safe removal techniques. The ingredients used in these products are safe when the application is performed by a properly trained nail professional.

The most popular types of artificial nails are acrylic nails, fiberglass nails, and gel nails. Acrylic nails are created by mixing liquid monomer and a powder polymer, which when combined form a hard protective layer that is sculpted over the natural nail. Gel nails are created by applying a gel polish to the natural nail and curing it under a UV or LED light. Polygel nails are a hybrid nail enhancement formula that combines the best of both acrylic and gel nails.

The materials used in artificial nail extensions include acrylonitrile butadiene styrene (ABS) for nail tips, fabric, fiberglass, or paper for wraps, and a slurry resulting from mixing the powder and liquid for liquid/powder systems. The ingredients used in these products are safe when applied by a properly trained nail professional. However, care should be taken to avoid prolonged or repeated direct skin contact, due to the skin sensitization potential of some ingredients. Discontinue use immediately if skin irritation occurs.

In summary, artificial nail extensions are a popular fashion accessory that can be created using various materials and techniques. The ingredients used in these products are safe when applied by a properly trained nail professional, but care should be taken to avoid prolonged or repeated direct skin contact, and discontinue use immediately if skin irritation occurs.
