Ingredients and why they matter
Isododecane is a lightweight solvent that helps formulas glide on smoothly and dry quickly, reducing weight on lashes for comfortable wear.
Cera Alba / Beeswax / Cire Dabeille provide structure and hold to maintain lash shape and volume over time.
Copernicia Cerifera Cera / Carnauba Wax / Cire De Carnauba contribute thickening properties that support a dense, dramatic lash line.
Disteardimonium Hectorite acts as a texturizing agent to stabilize the formula and prevent clumping during application.
Oryza Sativa Cera / Rice Bran Wax offers additional film-forming power for long-lasting wear and easy removal with proper cleansing.
Iron Oxides (CI 77499) provide the rich, couture-black pigment for the signature deep color.
Alcohol Denat. helps with rapid drying while ensuring formula stability; avoid contact with eyes if sensitivity occurs.
Other ingredients support pigment dispersion, texture, and wear, delivering a bold lash look that lasts while remaining comfortably flexible on the lash line.
Who this is for and usage tips
This mascara is ideal for anyone seeking ultra-long wear, high volume, and a strong black finish that resists sweat and heat. It’s well-suited for busy days, hot environments, or workouts where lashes should stay defined and lifted.
For best results, apply from the lash base to the tips in a zig-zag motion to separate lashes and avoid clumping. Build with each swipe and remove with a bi-phase cleansing product to break the longwearing formula.
Keep out of reach of children and follow the included instructions for use to ensure safe, optimal results. If irritation occurs, discontinue use and consult a professional if needed.
9 mL supplies the full-size mascara experience in a compact, long-wear product that supports dramatic lash volume without frequent touch-ups.
