LunaMoon Strong Base – 3-in-1 Hard Base, Gel & Top System LunaMoon Strong Base is a high-performance hard base with properties similar to a modeling gel. This versatile, hypoallergenic formula acts as a base, builder gel, and glossy top coat all in one, making it ideal for strengthening short to medium-length nails (up to 5mm free edge). Key Advantages: 3-in-1 Versatility: Combines the functions of a base coat, builder gel, and high-shine top coat. Superior Strength: Transforms thin and brittle nails into a hard, durable surface. Ultra-Glossy Finish: If the tacky layer is removed, it maintains a beautiful gloss that doesn't require an additional top coat. Fast Self-Leveling: Features a medium-liquid consistency that allows for perfect leveling in just seconds without running. Safe Formula: Hypoallergenic with a low-acid pH of 5–6. Easy Removal: Can be removed efficiently by either filing or professional soak-off liquids.
