Builder in a Bottle (BIAB) is a type of soak-off builder gel used in nail treatments, designed to strengthen and enhance natural nails. It's especially popular for clients looking to grow their natural nails or create a structured, long-lasting manicure without traditional acrylics or hard gels.
What Is BIAB Gel?
BIAB stands for Builder In A Bottle, a product typically offered in a bottle-and-brush format, much like standard gel polish. It combines the strength of builder gel with the ease of application of a regular gel polish.
Key Features:
- Strengthens Natural Nails: Ideal for brittle, peeling, or weak nails. It adds structure and prevents breakage.
- Soak-Off Formula: Unlike traditional hard gels, BIAB can be removed with acetone, making it gentler on the nails.
- Self-Levelling: The gel smooths itself out after application, reducing the need for excessive filing.
- Versatile Use: Can be used as a base layer, for natural nail overlays, or to build short extensions.
- Long-Lasting: BIAB manicures typically last 3–4 weeks with proper application and care.
Who Is It Best For?
- Clients who want to grow their natural nails
- Those prone to nail damage or breakage
- Nail techs looking for a healthier, non-acrylic strengthening option
- People wanting a low-maintenance, long-lasting manicure
Frequently Asked Questions: Builder Gel
What is the difference between hard gel and BIAB?
Hard gel is a non-soak-off formula used for building strong, extended nails and requires filing for removal. BIAB (Builder in a Bottle) is a soak-off builder gel ideal for overlays and natural nail strengthening, offering easier application and removal.
How do you apply builder gel?
Apply builder gel in thin layers over a prepped nail surface, curing each layer under a UV or LED lamp. Shape as needed, then finish with a top coat or gel colour. Proper prep and curing ensure durability and longevity.
