Frequently Asked Questions (FAQ)

Q: What is BIAB?

A: BIAB stands for Builder in a Bottle—a thicker, stronger type of gel polish that combines the flexibility of regular gel with the strength of builder gel. Belle Beauty’s builder gel in a bottle 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 Builder in a Bottle in thin layers, curing each layer under a UV or LED lamp. Finish with Belle Beauty Top Coat for a glossy, long-lasting finish. Always follow manufacturer curing times for best results.

Q: How long does BIAB last?

A: When applied correctly, Belle Beauty BIAB nails can last up to 3-4 weeks without lifting or chipping. Longevity depends on nail prep, application technique, and aftercare (such as wearing gloves when cleaning and using cuticle oil regularly).

Q: How do I remove BIAB at home?

A: To safely remove at home:

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 softened Builder in a Bottle with a cuticle pusher. Never force it!
5. Buff and nourish nails with cuticle oil afterward.

For healthier nails, avoid peeling or scraping hard.

Q: Can beginners use BIAB?

A: Yes! Belle Beauty’s Builder in a Bottle is beginner-friendly thanks to its smooth, self-levelling formula and easy brush-on application. It’s perfect for aspiring nail technicians and home users who want salon-quality results without the hassle.

Q: Does Belle Beauty BIAB help strengthen natural nails?

A: Absolutely. Our formula reinforces the natural nail, helping to protect against splitting, peeling, and breakage. Over time, many users notice stronger, healthier nails beneath their BIAB overlays.

Q: Do I need a base coat with BIAB?

A: For optimal adhesion and durability, we recommend using Belle Beauty Base Coat under your Builder Gel in a Bottle application. This helps anchor the product to the nail plate and extends the life of your manicure.

Q: What lamp should I use to cure BIAB?

A: Our collection can be cured under both UV and LED lamps. Belle Beauty's UV Nail Lamp is ideal for curing Builder in a Bottle!
