Product Overview

UNA GELLA's 7-in-1 Clear Hard Builder Gel is a professional-grade solution designed to transform weak, brittle nails into strong, beautiful canvases. Whether you want to add length, create a flawless apex, or simply reinforce your natural nails, this hard gel delivers exceptional performance. Formulated as a clear, self-leveling gel, it cures under an LED lamp to a durable, non-yellowing finish that lasts for weeks. Perfect for both beginners and experienced nail enthusiasts, this builder gel simplifies your nail routine by combining multiple steps into one product.

Key Features & Benefits

  • 7-in-1 Versatility: Acts as a builder gel, apex gel, extension gel, strengthener, base coat, overlay, and even a nail tip adhesive – all in one bottle.
  • Hard & Durable: Cures to a rock-hard finish that resists chipping, cracking, and everyday wear, ensuring your manicure stays flawless longer.
  • Self-Leveling Formula: Spreads smoothly and evenly, reducing filing and shaping time for a professional look.
  • Clear & Non-Yellowing: Maintains its crystal-clear transparency over time, perfect for natural looks or as a base for colored polish.
  • Strengthens Natural Nails: Adds a protective layer that prevents breakage and promotes nail growth, ideal for weak or damaged nails.
  • Easy Application: Works with forms or tips for extensions, or directly on natural nails for a strengthening overlay.
  • LED Lamp Required: Cures quickly under any standard 48W+ LED lamp, saving you time.

How to Use

  1. Prep: Clean and shape your nails, push back cuticles, and buff the surface lightly. Apply a dehydrator and primer for better adhesion.
  2. Apply Builder Gel: Using a brush, apply a thin layer of UNA GELLA Builder Gel to the nail. For extensions, place a nail form or tip and apply gel to build the desired length and apex.
  3. Cure: Place your hand under an LED lamp (48W or higher) and cure for 60-90 seconds. For thicker layers, cure in stages.
  4. Shape & Finish: Once cured, wipe off the sticky residue with alcohol. File and shape as desired. Top with a gel top coat for extra shine or leave natural.

Who It Is For

This builder gel is ideal for anyone looking to strengthen weak or brittle nails, add length without salon visits, or create a smooth, professional apex. It suits DIY nail artists, beauty enthusiasts, and professionals who want a reliable, all-in-one gel that saves time and money. Whether you're a beginner or an expert, the self-leveling formula makes application easy.
