Frequently Asked Questions About Our BIAB (Builder in a Bottle) Products

What is Builder in a Bottle (BIAB)?

BIAB stands for builder gel in a bottle, a type of soak-off gel polish that strengthens and enhances natural nails. It bonds to the nail plate and builds a protective overlay that makes it a great alternative to traditional acrylics or dry hard gels, with a much gentler removal process and far less lifting than regular gel polish.

What exactly are BIAB Nails?

BIAB nails are natural nails reinforced with a builder gel that cures under a UV/LED lamp. The gel bottle formula bonds to the nail bed, building a thick, flexible strengthening barrier across the nail plate. The result is a painted, shaped nail with lasting shine and real durability, without the weight of acrylics. Unlike regular gel polish, BIAB nails actively help nails grow longer and stronger.

Is BIAB Better Than Gel Manicure Products?

For nail health, yes. Standard gel manicure and regular gel polish products sit on the nail plate as a colour layer only. Gella BIAB goes further: the self-levelling formula builds structure across the nail, promoting natural length and actively strengthening damaged nails over time. Our expert advice and that of most beauty editors: if lifting and breakage are a concern, switch from gel polish to BIAB.

What Are the Downsides of BIAB?

BIAB is one of the most nail-friendly systems available. The main things to know: cuticle work and removing oils from the nail plate before BIAB application are essential to prevent lifting. A primer also helps with longevity. For short nails or anyone new to professional use products, start with an overlay before attempting extensions on one nail at a time.

How Long Does BIAB Last?

With proper cuticle work, prep, and care, Gella builder gel lasts 2-3 weeks without chipping or peeling. Nail health, lifestyle, and keeping cuticles and oils maintained between appointments all contribute to durability and reduce lifting.

How Do I Apply Builder in a Bottle (BIAB)?

The BIAB application is different to regular gel polish.

1. After prepping the nail plate and completing cuticle work, apply a base coat and cure.
2. Apply a thin layer of builder gel from the gel bottle as a slip layer and cure under a UV/LED lamp.
3. Apply a second thin slip layer uncured, add a medium-sized bead moving side wall to side wall to distribute the self-levelling formula evenly, turn the finger upside down to build an apex, then cure.
4. Finish with gel polish, nail art, or a top coat for maximum shine. Follow this expert advice for best results and to avoid lifting.

Can I Soak It Off?

Yes. The removal process is simple: soak with acetone and file off whatever remains. Far less damaging to the nail bed than acrylic removal, making it a gentler choice for nail health than both acrylics and regular gel polish.

What is the Ideal Nail Length for BIAB Application?

Builder gel can be applied to any nail length, from short nails to long nails. The protective overlay works on every natural length and shape, helping all nail types grow longer over time. It is one of the most versatile BIAB products available.

What is the Price of Your Builder Gel Products?

The price varies depending on the specific product and size. You can find the price listed on each individual product page.

Are Your Builder Gel Products Cruelty-free?

Yes, our Cruelty-free Builder in a Bottle products are also vegan. We do not test our brand products on animals.

Do You Have a List of Ingredients for Your Builder Gel Products?

Yes, the ingredients for each product are listed on the individual product page. You can also find them by scanning the barcode on the gel bottle.

Can I Use Builder in a Bottle to Create a False Nail Look?

While builder gel is primarily designed to strengthen damaged nails and support natural length, it can create a natural-looking extension on one nail or a full set with the help of a nail form.

What is Your Most Popular Builder in a Bottle Colour?

Our most popular colour is Gella Nude, a versatile neutral complementing any skin tone and outfit. It is the perfect base for nail art and a bestseller in nail salons and home BIAB manicure kits alike.
