What is a key characteristic of gel nail enhancements?

Gel nail enhancements are distinguished by their requirement for UV or LED light to cure, which is a fundamental characteristic of this type of product. When the gel is applied to the natural nail or a nail tip, it remains in a semi-liquid state until it is exposed to the appropriate light source. The light initiates a chemical reaction, causing the gel to harden and bond to the nail surface, resulting in a durable finish.

This process not only facilitates a strong hold but also allows for a glossy appearance upon curing without the need for additional topcoats, which is a distinct advantage over other types of nail enhancements that air dry. The use of UV light also enables quicker application times and enhances the overall strength of the gel compared to those that do not require curing.

Other choices highlight aspects that are not true of gel nails. For instance, gels do not air dry, as they specifically need light to set. They also tend to last longer than some traditional nail applications, making them a popular choice for extended wear. Additionally, gel nails can be quite flexible, often matching the natural movement of the nail better than acrylics, which can sometimes be more rigid.
