APUREE Builder Nail Gel Ultrapex HEMA-Free — 60s Self-Leveling with Keratin & Biotin

APUREE Ultrapex™ Builder Nail Gel is a HEMA-free, clinically validated builder gel that sculpts a lasting apex in 60 seconds while infusing nails with keratin and biotin for structural improvement.

Designed for technicians and beauty-savvy users who want a salon-grade overlay without common allergens, APUREE Ultrapex blends a high-performance self-leveling system with a patented macromolecule barrier to minimize dermal penetration. The formula focuses on reinforcement rather than only concealment: it builds a controlled, vertical arch while delivering bio-based ingredients and a low-heat cure for comfortable application. Certified under strict standards and free from 26 suspect ingredients, this builder gel prioritizes strength, safety, and a high-gloss finish.

How does Ultrapex create a durable apex so quickly?

Ultrapex uses a smart self-leveling oligomer designed to flow into depressions and form a consistent longitudinal apex without heavy manipulation. The rheology balances viscosity with flow so the gel spreads and settles in about 60 seconds, allowing technicians to sculpt less and achieve predictable structure faster.

• Ultrapex 60s self-leveling for consistent apex formation
• Designed viscosity to fill valleys and erase ridges
• Reduces shaping time while improving peak durability

What makes this formula safer for sensitive nail beds?

APUREE’s patented macromolecule approach produces oligomers too large to penetrate deep skin layers, limiting allergenic exposure. Combined with HEMA-free chemistry and rigorous external certification, this formula aims to reduce common contact risks while maintaining performance.

• Patented large-molecule barrier minimizes dermal infiltration
• HEMA-free and TPO-free to lower typical sensitivities
• DermaTest-certified hypoallergenic performance

How does the product support nail health beyond appearance?

Beyond adding thickness, the gel is enriched with hydrolyzed keratin and biotin to support the nail plate environment. The ingredients are selected to anchor within the nail structure and deliver reinforcing benefits rather than only sitting on the surface.

• Hydrolyzed keratin integrates with the nail keratin network
• Biotin included to support nail structure and resilience
• Formulated for rehabilitative support, not just cosmetic overlay

Will curing be comfortable and complete on thick overlays?

The Derma-smart cool-cure system is engineered to reduce exothermic heat and maximize polymer conversion across layers. This closed-loop gel-and-lamp synergy targets high conversion rates and low heat, aiming to eliminate uncured residues and minimize post-cure sensitivity.

• Cool-cure polymerization reduces heat spikes during curing
• High conversion efficiency to limit uncured monomers
• Optimized for layered applications and professional lamps

Who this is for: APUREE Ultrapex builder gel suits nail professionals, technicians, and experienced at-home users seeking a high-strength overlay with reduced allergenic potential. It is ideal for repairing thin or damaged nails, creating long-lasting apexes for natural or extended enhancements, and for clients who request cleaner, bio-based formulations. Each purchase also includes an instructional guide and patch-testing protocol to help users apply the system safely and consistently.
