Frequently Asked Questions (FAQ)

Q: What is BIAB?

A: Builder in a Bottle is 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 it last?

A: When applied correctly, our products 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: Is your formula HEMA & TPO Free?

A: Absolutely! All our Builder Gel in a Bottle's are HEMA & TPO Free, ensuring a significantly reduced risk of allergic reactions. They also comply with EU regulations banning TPO, so they're extremely safe to use. While other brands have sacrificed quality, our products are still an ultra-thick consistency and easy to apply!

Q: How do I remove 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 Builder Gel in a Bottle?

A: Yes! Belle Beauty’s formula 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 Builder Gel in a Bottle 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 overlays.

Q: Do I need to apply a base coat?

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