What Are Builder Gel Nails?

Are builder gel nails worth it? In short: Yes, especially if you’re a nail-biter and want to strengthen and lengthen your nails. What’s more, a builder gel manicure is chip-resistant for three to five weeks.

As if that wasn’t a strong enough case, a builder gel (or BIAB—a builder gel in a bottle) is a great option for growing out your natural nails and repairing them all at once, as the builder gel polish reinforces weak nails with its protective overlay. Think of builder gels as a step up from normal 4AE37AE9-1F6A-4514-869E-35AA4DC2F5C0gel nail polish. Read on to learn how it compares to other popular manicure options such as gel extensions, dip powder nails, acrylic nails, and gel nail polish.

What Is Builder Gel?

Builder gel is a type of gel polish with a thick viscosity that creates length, thickness, and strength for your natural nails or nail tips. The gel polish formula combines the effects of a primer, base coat, and builder gel all in one bottle.

Builder gel can be separated into two categories: BAIB (builder gel in a bottle) and hard gel. Typically, BIAB is a thick gel that adds a durable overlay to the nails or nail tips to repair, strengthen, and grow your natural nails over time. But despite its thickness, builder gel is lightweight and offers a soft, natural finish. That makes it a more effective option than traditional gel nail polish.

If you’re a nail-biter, think of a builder gel manicure as armor that protects your nails from your teeth because it’s too rigid to bite through. That also makes it chip-proof, and it stands up to nail-biting, household chores, typing, etc. for about three to five weeks. If you’re wondering how to remove builder gel from nails and whether it’s a hard, lengthy process, fret not. It’s quite simple: Just soak it off with acetone and you’re good to go.

Builder gel also comes in various colors; clear, nude, and light pink are the most common shades. You can use builder gel like your average nail polish, or layer it to strengthen your nails (called an overlay) and top it off with a traditional gel or nail polish to add color or trendy nail art. You can also create short gel extensions or use it as glue to bond pre-shaped gel extensions to the natural nail.

What about a hard gel vs. a builder gel? Well, hard gel is another type of builder gel that adds a rigid layer over the nail. It comes in many different colors and finishes, typically in a pot. The biggest difference between builder gel in a bottle and hard gel is that the latter has to be filed off; it can’t be soaked off. Hard gel is similar to acrylic in that it’s strong on the nail, while builder gel has more flexibility, so it’s less likely to crack. Although a softer gel like BIAB is best for natural-looking nails and short extensions, a hard gel works better for extra-long nail extensions because it adds more strength.

How Does Builder Gel Work?

Builder gel application is different from traditional nail polish. The nails are cleaned, shaped, and buffed to help the base coat adhere to the nail. It’s best to clean your cuticles before applying builder gel.

Typically, a bead of builder gel is applied gently to the nail to build up and strengthen the apex of your nail (the highest point on your nail bed). While traditional nail polish is applied with long vertical strokes, builder gel goes on with small, horizontal strokes to ensure the polish goes across the entire nail.

If you’re using hard gel in a pot, then a separate brush is used to apply the gel to your nails. Both BAIB and hard gel are applied to the nail and cured with a UV nail lamp. Protect the skin on your hands from damaging UV rays by applying an SPF 30 or greater, like the L’Oréal Paris Bright Reveal Broad Spectrum SPF 50 Daily UV Lotion, to your hands and fingers before your gel manicure.

Expect builder gel to cost anywhere from $40 to $80+ depending on where you live, what salon you go to, and what color, design, and length you get. While builder gel nails can be achieved at home, there is a learning curve to perfecting them. BIAB requires a bit more effort and skill than traditional gel polish because it’s not just painted on in vertical strokes—it’s swiped across the nail to build up the apex and add strength. If builder gel is applied incorrectly, it can result in thick, uneven, and bumpy nail polish.

How Long Does Builder Gel Last?

Builder gel lasts about three to five weeks. Due to its strong, viscous texture, it’s less prone to lifting, like regular gel nail polish. Builder gel and hard gel can be filled so you don’t need a new set every time you get your nails done. A fill focuses on the outgrowth at the base of your nail, filling in the empty space with new builder gel to make your manicure look fresh.

How Does Builder Gel Differ From Other Manicure Types?

There are countless manicure options: builder gel nails, gel extensions, dip powder nails, acrylic nails, and gel nail polish. While these methods come down to personal preference, it’s also important to know which technique will keep your natural nails in good condition, how much work it requires to get them done (and the upkeep), and how to remove them.

Builder gel vs. acrylic nails

Builder gel isn’t as strong as acrylic nails, but it has more flexibility. That means builder gel nails are less likely to break if you hit them on a hard surface, giving them their chip-resistant reputation. While it’s good to have strong nails, especially if you’re using nail extensions or tips, a polish with flexibility offers durability against wear and tear and is less damaging if you break a nail. Builder gel in a bottle leaves a light, thin coat on your nails, making it faster to apply. It also allows your nails to grow and remain healthy while you wear the polish. If you’re looking to lengthen and strengthen your natural nails, BIAB is the better choice.

Another caveat to keep in mind with acrylic vs. builder gel is that acrylic requires excess nail filing before application and during removal. That leaves greater potential for damage—nail filing thins the natural nails, and the rigid acrylic shell can break your nails if you hit your hand on anything.

Builder gel vs. dip powder

Both builder gel and dip powder offer a mix of flexibility and durability that adds thickness and strength to the nail. They also offer a chip-resistant and long-lasting effect. However, the builder gel creates a more natural-looking finish, whereas the dip powder is bulkier on the nail.

The application process of dip powder is also more extensive than builder gel. It involves applying a base coat, dipping the nail into colored powder, and then sealing it with a top coat. Removing dip powder also requires nail filing and soaking, which is not only time-consuming but can lead to brittle, weak nails over time. One of the biggest perks to getting dip powder, however, is that you don’t need UV lighting—a step that’s required for builder gel polish—for curing.

Builder gel vs. gel extensions

Gel extensions are a popular manicure option because the process is quick and convenient. The gel tips are pre-made and designed to mold to the natural nail. Plus, the application is easy: The extension is glued on with a gel adhesive and cured with a UV light. Hard gels or builder gels require a few more steps, including cleaning, shaping, and buffing, as well as brushing the polish in a particular horizontal motion.

The biggest advantage to using a hard gel vs. gel extensions is that it’s more durable, flexible, and customizable to your nail shape. Moreover, builder gels maintain the health of the natural nails, making them grow and build strength in the long run.

Builder gel vs. regular gel manicures

Builder gel is a type of hard gel, so it’s a much more durable and long-lasting option than gel nail polish. In addition, builder gel strengthens and lengthens the nails while also protecting them from further damage.

A regular gel manicure doesn’t last as long—typically two weeks—and weakens nails in between, making them brittle and flaky. However, there are some perks to gel polish that a builder gel can’t quite offer, including a glossier finish and an endless array of nail polish colors. Moreover, a gel manicure is better suited than builder gels for nail art. Both types of techniques feature similar application and removal processes.

Does Builder Gel Damage Your Nails?

Builder gel polish is effective at re-strengthening weak nails and growing them out, causing minimal damage to your nails over time. However, removing builder gel requires soaking them in acetone, which can make nails dry or brittle. It’s best to give your nails a break between applications, allowing them to breathe and recover from the budge-proof polish and acetone removal. It’s important to apply the builder gel correctly, brushing the polish in horizontal strokes, so that it properly adheres to the nail.

How Do You Remove Builder Gel?

You can soak off most builder gel formulas at home with foil, acetone, and cotton, just like your average gel polish. Hard gel nail polish, on the other hand, should be removed at the salon by a professional since it needs to be filed off. If you know how to properly use an e-file (an electronic nail file) without damaging your natural nails, then you can carefully remove hard gel at home.
