Acrylic nails require which of the following for application?

Acrylic nails are created through a specific process that involves the use of a polymer powder. This powder is a crucial component in the formation of the acrylic material. When combined with a liquid monomer, the polymer powder undergoes a chemical reaction that allows it to harden and adhere to the natural nail or nail tip. This process forms a strong, durable nail enhancement that can be shaped and designed according to the client's preferences.

The other options mentioned—gel top coat, base coat, and top coat—serve different purposes in the nail application process but are not essential for the application of acrylic nails. A base coat is typically used as a protective layer prior to applying polish, while a gel top coat provides a glossy finish for gel manicures. Although top coats are used to seal and protect nail enhancements, they do not play a role in the foundational application of acrylic nails themselves.
