Builder In A Bottle — the strongest, most flexible nail enhancement for natural nails. Applied by specialist technicians at CH Nail Spa, Beauchamp Place, 2 minutes from Harrods.
What are BIAB Nails?
BIAB (Builder In A Bottle) is a revolutionary soft-gel builder product that is applied directly over your natural nail to add strength, flexibility, and a small amount of structure. Unlike hard acrylics, BIAB is flexible — it moves with your nail, dramatically reducing breakage. It's finished with your choice of gel polish for a flawless, long-lasting result.
BIAB is particularly popular for clients with weak, brittle or damaged nails looking to build strength over time. At CH Nail Spa in Knightsbridge SW3, we apply BIAB using The GelBottle Inc products, favoured by nail professionals worldwide.

What is BIAB (Builder In A Bottle)?
BIAB stands for Builder In A Bottle, a flexible, soft-gel builder product applied directly to the natural nail. It strengthens and protects the nail while adding a small amount of length or structure, then is finished with gel polish. It's ideal for clients who want stronger nails without the bulk of acrylics.
How long do BIAB nails last?
BIAB nails typically last 3–4 weeks and grow out cleanly, making infills straightforward. Because the product is flexible, it moves with your natural nail, reducing the risk of breakage.
Is BIAB good for weak or damaged nails?
Yes — BIAB is one of the best treatments for clients with brittle, weak, or damaged nails. It acts as a protective shield while your natural nails grow underneath, helping to restore nail health over time.
What's the difference between BIAB and gel extensions?
BIAB adds minimal length and strength directly over the natural nail, while gel extensions use a tip or form to add significant length. BIAB is more natural-looking and nail-friendly for everyday wear.
