A multiuse formula designed to help simplify your at-home manicure or pedicure routine. As a base coat, it preps and primes nails for polish, and when used as a top coat, it helps seal in color to prevent chipping or fading.

  • Formulated without: Formaldehyde, Toulene, DBP, Camphor, Ethyl Tosylamide, Acetone, Xylene, TPHP, or Formaldehyde Resin
  • Vegan, paraben-free and cruelty-free

Apply a thin coat to bare nails. Once the first layer has dried, apply 1-2 coats of lakur as needed. Let the polish dry for 10-15 seconds. Apply once again over polish to seal in color as a top coat. To expedite the drying process, apply 1-2 drops of Accelerating Drying Oil at the cuticle and allow the oil to run to the free edge of the nail.

For best results, reapply as a top coat every 3-4 days to refresh color and help extend wear time.

Ethyl Acetate, Butyl Acetate, Nitrocellulose, Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer, Acetyl Tributyl Citrate, Isopropyl Alcohol, Sucrose Acetate Isobutyrate, N-Butyl Alcohol, Etocrylene, Trimethylpentanediyl Dibenzoate, Dimethicone, Trimethylsiloxysilicate, Benzyl Benzoate, CI 60725

    High Shine

    I love this Duplex Base and Top Coat ! I applied this every 4 days and my nail color lasted me 10days without any chipping. On the 13 days I removed it. I used thin coats.
