Buying Guide
- Strength vs. flexibility: Look for gels labeled as builder or base gels with 6-in-1 or 7-in-1 functionality to maximize versatility while maintaining nail health.
- Base and top coat requirements: Some gels perform best when used with specific base and top coats to prevent lifting and ensure smooth curing.
- Allergy considerations: If you have sensitive skin, consider HEMA-free formulas to minimize irritation.
