Buying Guide
What should you consider when choosing a builder gel?
- Application and cure method: Do you prefer UV, LED, or a dual-cure option? Check curing times and compatibility with your lamp.
- Viscosity and workability: A thicker gel builds strong layers but can be harder to control; a medium viscosity offers easier shaping with still-strong results.
- Adhesion and base/top coats: Some gels require specific base or top coats to prevent lifting and ensure a lasting finish.
- Removal process: Soak-off formulas are gentler on natural nails; consider ease of removal if you like changing styles frequently.
- Durability versus flexibility: For longer wear, look for gels with good rigidity that still allow natural nail growth without cracking.
- Color options and finishes: If you want color options in one kit, choose multi-color sets; otherwise, clear gels work for French overlays and sculpting.
