What is one characteristic of UV gel nails?

UV gel nails are known for being glossy and durable, which are two of their most prized characteristics. The glossy finish is the result of the gel's unique formulation, which reflects light beautifully when applied and cured under a UV lamp. This shine contributes not only to the aesthetic appeal but also helps in protecting the nails from chips and scratches, enhancing their longevity.

Moreover, their durability comes from the chemical properties of the gel, which create a hard surface that adheres strongly to the natural nail. This results in nails that can withstand daily wear and tear much better than other nail enhancements, making them a popular choice among clients looking for a resilient manicure.

The other options do not accurately describe UV gel nails: they are not typically matte or fragile; they are lightweight rather than thick and heavy; and they indeed require curing under UV light to harden and set properly.
