Gel nail extension is a process that involves hard gel built on a natural nail and cured with UV light. The manicurist uses a nail form, which is basically a sticker that goes under the free edge (the tip) of the nail, to extend the length of the nail.

When it comes to either getting a box of pre-shaped gel nail extensions or actually creating them, the nail technician needs first to prepare the nails (file, clean, and buff nails). Then, the expert applies a form underneath the natural nail to create the length one by one with a gel builder, a gel primer, and a gel top coat, letting them dry under the LED or UV light.

Both acrylics and gel can be used to create nail extensions. They also usually have a similar look, although gel tips may feel lighter. It's mainly about the structure of the nail, but the real difference lies in the polymerization process, ease of removal, and density. "The process of using gel is definitely quicker. There are no strong odors and you won’t have the hassle of filing or dealing with dust," explains Seney. "With acrylic nails, you have to mix a liquid called monomer and a powder (polymer) to mold the artificial nail."
