How to Apply for Strong, Long‑Lasting Nails

1. Prep Nails: Start with clean, makeup‑free nails. Remove any old polish and gently push back cuticles.
2. First Coat: Apply one thin layer of Diamond Strength across each nail, covering the entire nail plate.
3. Second Coat (Optional): For extra reinforcement, apply a second coat after the first has dried.
4. Daily Wear: Wear as a stand‑alone clear polish or under your favorite nail color.
5. Re‑Apply Every 5–7 Days: Maintain protection by reapplying after a week or when you notice wear.

Expert Tip:

Allow each coat to dry completely before applying the next to maximize durability and shine.

Why Micro‑Diamond Technology Matters

Many nail hardeners rely on polymers that can leave nails feeling brittle. Diamond Strength incorporates micronized diamond particles that trap light, providing both strength and a luminous finish. Titanium adds flexibility, preventing brittleness and cracking, while platinum further enhances wear resistance and radiance.
