If you’ve worn acrylics for years and someone’s just told you about BIAB, you’re probably wondering whether it’s actually worth switching. Acrylics work. You know what you’re getting. Why change?
Or maybe you’ve never had either and you’re trying to figure out which one to start with, because the internet has strong opinions about both and none of them seem to agree.
Here’s a straightforward comparison from a nail tech who’s worked with both systems and made a deliberate decision about which one to offer clients.
Acrylic nails are created by mixing a liquid monomer with a powder polymer to form a paste that gets sculpted onto your natural nail or a tip. It hardens through a chemical reaction when exposed to air, not under a lamp. The result is a rigid, durable structure that can be filed into any shape and built to any length.
Acrylics have been the default extension system for decades. They’re strong, they hold their shape, and a skilled tech can build dramatic lengths and complex structures that would be impossible with natural nails alone. For people who want long stilettos, heavy embellishments, or extreme shapes, acrylics deliver structural rigidity that softer systems can’t match.
The trade-off is that traditional acrylic application uses a liquid monomer with a strong odour, and the product itself is rigid rather than flexible. When a rigid nail catches on something, it doesn’t bend, so a hard knock can break it. As with any enhancement, how the product is applied, maintained and removed makes a big difference to the natural nail underneath.
BIAB stands for Builder In A Bottle. It’s a builder gel applied as an overlay on your natural nail to add strength and structure. It gets cured under an LED lamp rather than air-setting like acrylic, so there is very little odour during application.
The texture is different from acrylics in a way that matters. BIAB has flex to it. It moves slightly with your natural nail rather than sitting on top as a rigid shell. When your nail bends under pressure, the BIAB can flex with it, which suits natural nails at natural to moderate lengths.
BIAB can be infilled rather than fully removed at every appointment. Your tech adds fresh product to the regrowth area, blends it into the existing overlay, and you’re done. Less filing, less acetone, less repeated trauma to the nail plate underneath. Over months of regular appointments, that difference adds up considerably.
At Aesthete Beauty, BIAB starts from £49. Infills from £49. BIAB with Russian manicure preparation from £79.
Strength: acrylics are harder and more rigid. BIAB is strong but flexible. For everyday life, BIAB’s flexibility is actually an advantage because it absorbs impact rather than transferring it to your natural nail.
Durability: acrylics last three to four weeks before an infill. For BIAB, maintenance is generally recommended around every three weeks, and you will be advised individually.
Weight: acrylics feel heavier on the nail, especially at longer lengths. BIAB is noticeably lighter, even as an overlay with some added length.
Fumes: acrylic application involves liquid monomer with a strong chemical smell. BIAB has very little odour because it cures under an LED lamp.
Removal: acrylics are filed down and then soaked in acetone, which takes time. BIAB can be soaked off or maintained through infills without full removal.
Nail health: any enhancement that is repeatedly filed off and reapplied can thin the natural nail over time, so how it is applied, maintained and removed matters. BIAB is usually maintained with infills, so the overlay stays on and is refreshed rather than removed and rebuilt at every appointment.

Acrylics aren’t bad products. They serve a specific purpose that BIAB doesn’t fully replace.
Extreme length. If you want nails that extend well past the fingertip in shapes like stiletto or coffin, acrylics provide the structural rigidity needed to support that length without breaking. BIAB can add moderate length, but it’s too flexible for extreme extensions.
Heavy nail art. Designs that involve significant three-dimensional elements, heavy embellishments, or layered textures need a rigid base. Acrylic gives techs more sculpting control for complex structural work.
Habit and familiarity. Some clients have worn acrylics for years and genuinely prefer the feel. A rigid nail with some weight to it is what they’re used to, and BIAB feels too natural for what they want. Preference is valid, and no one should tell you your choice is wrong if that’s genuinely what you prefer.
For many people who get their nails done, BIAB gives the support and finish they want at natural to moderate lengths.
If your goal is natural-looking nails at natural to moderate lengths, BIAB gives you structure with very little odour and a lighter, more flexible feel.
Worth knowing if your workplace has rules about nail enhancements: policies differ between employers. Some workplaces, including many healthcare and food settings, do not allow any product on the nails, so check your employer’s policy before booking.
If you’ve worn acrylics for a long time and your natural nails are thin or peeling, BIAB can help. The overlay protects the natural nail while it grows, which can reduce everyday breakage, and the condition of your nails is assessed at every appointment.
And if you’re starting from scratch and have never had either, BIAB is an easy place to start. It looks natural, it can be maintained with infills, and it’s straightforward to remove professionally if you decide it’s not for you.
Yes. Clients do this regularly at Aesthete Beauty.
The process starts with professionally removing the acrylics, which involves filing down the bulk of the product then soaking the remainder in acetone. Your tech will assess the condition of your natural nails after removal. If they’re in decent shape, BIAB can go on the same day. If there’s significant damage, a recovery period of one or two weeks with nail oil and IBX treatment might be recommended first.
First-time BIAB after acrylics feels different. Lighter. More flexible. Some clients love it immediately. Others need one or two appointments to adjust to the feel.
One thing to be honest about: if you’ve had very long acrylics for years and you switch to a natural-length BIAB overlay, the visual change is significant. Your nails will look shorter and more natural, and that adjustment takes a few weeks to settle into. In return, your natural nail is supported while it grows, and many clients find the transition worth it.
Is BIAB as strong as acrylic nails?
BIAB is strong but flexible, while acrylics are strong and rigid. For everyday use at natural to moderate lengths, BIAB provides more than enough strength. For extreme lengths or heavy sculptural work, acrylics have an edge because of their rigidity.
Do BIAB nails last as long as acrylics?
Both are maintained with infills. For BIAB, maintenance is generally recommended around every three weeks, and you will be advised individually.
Is BIAB less damaging than acrylics?
BIAB’s infill system means less filing and less acetone exposure over time, because the overlay is refreshed rather than removed at every appointment. With any enhancement, correct application and professional removal help protect the natural nail.
Can I get long nails with BIAB?
BIAB can add moderate length through sculpting. For extreme length, nail extensions are more suitable because they provide the rigidity needed to support nails well past the fingertip.
Why doesn’t Aesthete Beauty offer acrylics?
Aesthete Beauty does not offer acrylics. Traditional acrylic systems use a liquid monomer with a strong odour, and the salon is kept as a fresh, odour-free environment. For clients who want extensions, Polygel, BIAB and Builder Gel nail extensions are offered instead of acrylics.
Are BIAB fumes harmful?
BIAB has very little odour because it cures under an LED lamp rather than air-setting like acrylic. Acrylic application involves liquid monomer fumes that require proper ventilation. All products at Aesthete Beauty are also HEMA-free and TPO-free.
How much does BIAB cost compared to acrylics?
BIAB at Aesthete Beauty starts from £49. BIAB with Russian manicure from £79. Acrylic prices vary by salon but typically range from £30 to £60 depending on length and design.
Can I still get nail art with BIAB?
Yes. BIAB provides a good base for nail art, including chrome, cat-eye, hand-painted designs, French tips, glitter and ombre. Nail art is charged separately depending on the design complexity.
If you’ve been thinking about switching from acrylics to something lighter and more natural-looking, BIAB is worth trying. Radina has over 11 years of experience in the industry and can assess your nails, recommend the right approach, and get you started with a system that works long-term.
