Frequently Asked Questions (FAQ)

Q: What is BIAB?

A: BIAB (Builder in a Bottle) is a thicker, stronger type of gel polish that combines the flexibility of regular gel with the strength of a hard builder gel. Belle Beauty’s BIAB gel allows you to strengthen, enhance, and even extend your natural nails easily, without the need for messy pots or brushes.

Q: How do you apply BIAB nails?

A: Start by prepping the natural nail (buff, cleanse, and push back cuticles). Apply a thin layer of Belle Beauty Base Coat and cure it. Then, apply your BIAB gel in thin layers, curing each layer under a UV or LED lamp. Finish with a Top Coat for a glossy result.

Q: How long does a BIAB manicure last?

A: When applied correctly, our BIAB products can last up to 3-4 weeks without lifting or chipping. Longevity depends on nail prep and aftercare (such as using cuticle oil regularly).

Q: Is your formula HEMA & TPO Free?

A: Absolutely! All our Builder in a Bottle gels are HEMA & TPO Free, ensuring a significantly reduced risk of allergic reactions. They comply with EU regulations, making them a safe choice for your natural nails.

Q: How do I remove BIAB gel at home? 

A: To safely remove your builder gel:

1. Gently file the top layer to break the seal.

2. Soak a cotton ball in acetone and place it on the nail.

3. Wrap the nail in foil and leave it for 10–15 minutes.

4. Gently push off the softened BIAB with a cuticle pusher.

5. Buff and nourish nails with cuticle oil afterward.

A: Yes! Belle Beauty’s formula is beginner-friendly thanks to its smooth, self-levelling consistency. It’s perfect for aspiring nail techs and home users who want salon-quality BIAB nails without the hassle.
