F.O.X Builder Gel Flashback is a three-phase thick-viscosity builder gel designed for strong nail architecture and extensions. The hard formula ensures structural stability, precise arch retention and resistance to deformation.

The gel has a dense consistency and levels slowly, allowing full control during application. It does not run, making it suitable for beginners and for building defined shapes. The low-temperature formula minimizes discomfort during curing.

• Hard material for durable modeling
• Perfect arch retention
• No burning sensation in the lamp
• Maintains a clean smile line
• Volume: 15 ml / 0.5 fl.oz.

Important: in low temperatures the gel may become thicker and more difficult to work with.

If you need a more fluid, faster self-leveling texture, consider Hard Gel.

For complex shapes that must hold before curing, choose Jelly Gel (non self-leveling).

How to use:

1. Nail preparation. Apply F.O.X Nail Prep to remove oils and moisture. Use F.O.X Ultrabond (acid-free primer) for additional adhesion.
2. Base layer. Apply any elastic base (e.g., F.O.X Power Base or F.O.X Rubber Base) with rubbing motions. Cure for 1 minute in a 36W UV lamp or 30 seconds in a 36/48W LED/UV lamp.
3. Strengthening natural nails. Apply a thin first layer, working it into the surface. Cure for 1 minute in 36W UV or 30 seconds in 36/48W LED/UV. Apply a second leveling layer to build architecture. Cure for 2–3 minutes in 36W UV or 2–4 minutes in 36/48W LED/UV.
4. Extension using dual forms. Select the correct Dual Form size. Evenly distribute gel inside the form, place it on the nail and remove excess material. Cure for 2–3 minutes in 36W UV or 2–4 minutes in 36/48W LED/UV. Remove the form and refine with filing.
5. Extension using paper forms. Secure the form under the free edge. Create a thin base layer and cure for 2–3 minutes in 36W UV or 2–4 minutes in 36/48W LED/UV. Build architecture with additional layers, curing each layer accordingly. Remove the form and file to shape.

After modeling, the nail is ready for gel polish or top coat application.

Removal: file off using a hand file or nail drill.

Pro tip: instead of fully removing the protective foil, make a small opening to prevent leaks and accidental curing. Use the foil edge to remove excess product neatly.
