You’ve probably heard someone say BIAB is better than gel polish. Maybe your nail tech mentioned it, maybe you read it online, or maybe your friend swears by it and won’t stop going on about how her nails have never been stronger.
But is it actually better? Or just different?
The honest answer: it depends on your nails. They’re different products designed for different situations, and the right one for you comes down to what your nails actually need right now. Here’s how to figure that out.
Gel polish is a thin colour coating that gets cured under an LED lamp. It sits on top of your natural nail and gives you a glossy finish that lasts two to three weeks.
Gel polish is mainly about long-lasting colour and shine, and it suits nails you’re already happy with in strength and length.
When it’s time for a change, your tech soaks it off with acetone or files it back. Correct application and professional removal help protect the natural nail. Gel polish doesn’t change the structure of your nail at all, which is either a good thing or a limitation depending on what you need.
At Aesthete Beauty, gel polish starts from £43. The whole appointment takes about 45 minutes, and the gel we use is HEMA-free and TPO-free. HEMA-free does not mean allergy-free, so if you have ever reacted to gel nail products, please message us before booking.
BIAB stands for Builder In A Bottle. It’s a builder gel that gets applied as an overlay on your natural nail to add structure and strength. Think of it like a protective shell that supports your natural nail while it grows, which can reduce everyday breakage.
It’s thicker than gel polish but thinner than acrylics. You can feel the difference on your nails. There’s a slight weight to it, a bit of substance, but it still looks and feels natural. Most people who try it for the first time are surprised by how lightweight it is compared to what they expected.
BIAB maintenance is generally recommended around every three weeks, and you will be advised individually. And the best part: it doesn’t need full removal every time. You can get infills where your tech adds fresh product to the regrowth area without stripping everything off. That means less acetone, less filing, less stress on your natural nail over time.
At Aesthete Beauty, BIAB starts from £49. Infills are also from £49. Only £6 more than gel polish, which surprises a lot of first-time clients.
Here’s the quick comparison if you want it at a glance.
Durability: gel polish lasts two to three weeks. For BIAB, maintenance is generally recommended around every three weeks, and you will be advised individually.
Thickness: gel polish is thin, virtually invisible on the nail. BIAB adds a visible but natural-looking layer of structure.
Nail health: gel polish adds colour and shine rather than structure. BIAB adds structure that protects the natural nail while it grows, which can reduce everyday breakage.
Removal: gel polish soaks off in acetone every time. BIAB can be infilled multiple times before a full removal is needed.
Appointment time: gel polish takes around 45 minutes. BIAB takes about an hour.
Price at Aesthete Beauty: gel polish from £43. BIAB from £49. £6 difference.
Best for: gel polish suits healthy nails that just want colour. BIAB suits nails that need help, whether they’re thin, brittle, peeling, or recovering from damage.
If your nails are already strong and healthy and you just want a colour that lasts, gel polish is all you need. Spending extra on BIAB when your nails don’t need structural support is like buying hiking boots to walk to the shops.
Gel polish is also the better option if you like changing your colour every two to three weeks. Because it soaks off completely each time, there’s no commitment to maintaining an overlay between appointments. You can go from deep burgundy to nude to bright coral without worrying about what sits underneath.
If you prefer the thinnest, most natural feel on your nails, gel polish wins. Some people genuinely don’t like the slight extra weight that BIAB adds, even though it’s subtle, and that’s a good reason to stick with gel. Your nails should feel like your nails.
One more thing worth knowing: gel polish also makes sense as a starting point if you’ve never had your nails done professionally before and you’re not sure what you want yet. It’s the least commitment, the easiest to remove, and a good way to see whether you enjoy having your nails maintained before investing in an overlay system.
If your nails break at the same length every time, peel in layers, or feel paper-thin, BIAB can help. It creates a protective layer that absorbs the daily impacts your nails take, which can reduce everyday breakage, so many clients find they can keep their natural length.
BIAB is also a popular choice for clients moving away from acrylics. The overlay protects the natural nail while it grows out, which can reduce everyday breakage.
If your workplace has rules about nail enhancements, check them before booking. BIAB looks natural and is thinner than acrylics, but some workplaces, including many healthcare and food settings, do not allow any product on the nails, so check your employer’s policy before booking.
BIAB with Russian manicure preparation is the salon’s most popular combination. It pairs the structure of BIAB with very detailed cuticle work, so the product is placed precisely and the regrowth is less noticeable as your nails grow.
There’s also a psychological side to it that doesn’t get talked about much. When your nails stop breaking at the same frustrating length every single time, when you actually see them growing past the point where they’ve always snapped, something shifts. Clients who’ve struggled with weak nails for years often say their BIAB appointments feel more like progress than maintenance.
Gel polish aftercare is straightforward. Avoid soaking your hands in hot water for the first 24 hours, wear gloves when cleaning, and apply cuticle oil daily. When you notice lifting at the edges after two or three weeks, book your next appointment. Don’t pick at it.
BIAB aftercare follows the same basics but with one extra consideration: because the overlay has structure, you need to be conscious of impact. Slamming a car door on your nails, catching them on a zip, or using your nails as tools to pry open a lid can crack the overlay in a way that wouldn’t happen with flexible gel polish. The structural strength that makes BIAB protective also means it’s rigid enough to crack under sudden force rather than just flexing like gel polish would.
If a BIAB nail does crack or chip, don’t try to file it yourself. Book a nail repair appointment, which takes about fifteen minutes and costs £6 at Aesthete Beauty, and your tech will fix the damaged area without compromising the rest of the overlay.
For both products, daily cuticle oil makes a noticeable difference to how long your manicure lasts and how healthy your nails feel between appointments. It takes ten seconds and it’s one of the most useful things you can do for your nails between appointments.
Yes. They’re not permanent commitments and you’re not locked into either one.
Going from gel polish to BIAB is as simple as booking a BIAB appointment next time. Your tech removes the gel, applies BIAB, and you’re done.
Going from BIAB back to gel polish means having the BIAB professionally removed first, which takes a separate short appointment. Don’t try to pick or peel it off yourself, because that takes layers of your natural nail with it.
Plenty of clients alternate depending on the season or what their nails need at the time. There’s no rule that says you have to pick one and stick with it forever.
This is more common than most people realise. You can have BIAB applied as a structural base and then gel polish on top for colour. It gives you the strength of BIAB with the colour range of gel polish.
At Aesthete Beauty, you can also have BIAB finished with chrome, cat-eye, nail art, or French tips. The BIAB overlay is the base, and you can choose the finish that suits you.
If you’re not sure which approach suits you, mention it at your appointment. Radina will look at your nails and tell you honestly what she’d recommend. There’s no upsell pressure. If gel polish is genuinely all you need, she’ll say so, even though BIAB costs more. That kind of honesty is why clients keep coming back to Aesthete Beauty.
Is BIAB actually better for your nails?
Better is relative. If your nails are weak, thin, or damaged, BIAB is often the better choice because it adds structural support. If your nails are already strong and healthy, you may not need that support, and gel polish does the job well.
What are the negatives of BIAB?
It’s slightly thicker than gel polish, which some people notice at first. It costs a bit more per appointment. And if you want to switch to bare nails, you need a professional removal appointment rather than just soaking it off at home.
Should BIAB be removed every time?
No. That’s one of the advantages. BIAB can be infilled, which means your tech adds fresh product to the regrowth area without stripping everything off. Most clients go through two or three infill appointments before a full removal is needed.
Are BIAB infills worth the cost?
Yes. Infills from £49 at Aesthete Beauty maintain the overlay without the wear of repeated full removals. They’re quicker than a full application and kinder to your natural nail because there’s less filing involved.
Does gel polish damage natural nails?
Correct application and professional removal help protect the natural nail. Damage usually comes from picking or peeling the polish off, which tears the top layers of the nail plate, and professional soak-off removal helps avoid this.
How long does gel polish last compared to BIAB?
Gel polish lasts two to three weeks. For BIAB, maintenance is generally recommended around every three weeks, and you will be advised individually.
Can I do nail art with BIAB?
Absolutely. BIAB provides an excellent surface for nail art. Chrome, cat-eye, hand-painted designs, French tips, glitter, ombre. Nail art is charged separately depending on the complexity of the design.
Which is better if I’m pregnant?
Please mention your pregnancy on your consultation form, and check with your midwife or GP if you have any concerns. Hormone changes during pregnancy can sometimes affect how well both products adhere.
Healthy nails that just want colour? Gel polish.
Nails that need extra support while they grow, or that keep breaking? BIAB.
Want structural strength with your choice of colour on top? Both together.
