A New Dimension of Black: “Diamond Dust Black” Shines Bright
Launched as part of MASCODE’s Sleek Liquid Eyeliner collection, which debuted in October 2025, the “Diamond Dust Black” shade is a testament to the brand’s commitment to innovative beauty. This eyeliner features a sheer black base generously laced with classic silver and subtle blue micro-pearls. The result is a mesmerizing, transparent sparkle that catches the light, creating an impressive and radiant eye look without feeling heavy.
Beauty enthusiasts are already buzzing about how the “Diamond Dust Black” offers a refreshing take on classic black eyeliner, promising a “subtle yet striking twinkle that catches the light beautifully.”

Crafted for Precision and Lasting Beauty
The MASCODE Sleek Liquid Eyeliner is engineered for both ease of use and enduring performance. Its design focuses on delivering a flawless application every time:
-
Sparkling Transparency: A sheer black base with silver and blue micro-pearls creates a luminous, transparent effect that makes eyes appear clearer and more captivating. The pearls, including calcium aluminum borosilicate, tin oxide, silver, and silica, reflect light like diamond dust.

-
Ergonomic Design for Effortless Application: The eyeliner boasts a 0.1mm ultra-fine brush, designed for both flexibility and firmness, allowing for precise lines from lash gaps to winged tips. Its low-center-of-gravity aluminum casing and unique square-shaped end provide a comfortable, steady grip, minimizing hand shake.

-
Long-Lasting and Skin-Friendly Formula: This quick-drying, smudge-resistant eyeliner is robust against water, sweat, sebum, and friction, ensuring a pristine look throughout the day. It incorporates four moisturizing beauty ingredients—Sodium Hyaluronate, Swertia Japonica Extract, Rosa Canina Fruit Extract, and Chamomilla Recutita (Matricaria) Flower Extract—and is dye-free to be gentle on the delicate eye area. Despite its waterproof claims, it can be easily removed with facial cleanser.
