Fake nails with a gel finish can be called gel extensions, gel overlays, or gel sculpted nails, depending on the application method. These refer to artificial nails enhanced with gel polish or gel builder for added strength and a glossy finish.

Gel is generally considered gentler on the natural nail than dip powder. Dip powder application often involves more filing, which can thin and weaken the natural nail, whereas gel can be soaked off more easily.

Gel fake nails typically last between two to three weeks. The longevity depends on factors like application quality, nail growth rate, and how well they're cared for after application.

The 'better' option depends on your goals; gel nails are a polish applied to natural nails or short extensions to add color and shine. Fake nails (acrylic or sculpted) add significant length and strength, ideal for those wanting dramatic transformations or needing extra durability.
