Rimmel Lash Accelerator Endless Volume Mascara — 003 Extreme Black, Micro-Fiber Lengthening & No-Clump Formula

Rimmel Lash Accelerator Endless Volume Mascara is a micro-fiber, ultra-lengthening mascara in Extreme Black that separates lashes without clumps and supports visibly longer-looking lashes with continued use.

This mascara combines a lightweight micro-fiber formula with Rimmel’s Grow-Lash Complex to build length and thickness while a specially designed brush captures each lash for even separation. The shade 003 Extreme Black delivers intense pigment in a compact 0.33 oz tube, and the formula is formulated to layer without flaking or clumping. It’s sold exclusively at Walmart and is designed for daily wear and gradual enhancement of lash appearance over time.

How does the micro-fiber formula lengthen lashes?

The micro-fibers in the formula adhere to the tips of natural lashes to create measurable extension without heavy buildup. Lightweight binders keep the fibers in place so lashes look longer and remain flexible rather than stiff. Over repeated application, the effect accumulates for a more pronounced lengthened look.

• Micro-fibers attach to lash ends for visible extension
• Lightweight base prevents flaking and stiffness
• Buildable layering allows gradual length increase

Will this mascara separate lashes and avoid clumps?

Yes — the brush is engineered to catch and coat individual lashes, promoting separation and even coverage from root to tip. The formulation resists clumping by balancing fibers and binders, so you can add layers without the spidery look. Expect clean definition and a fan-like finish with each coat.

• Precision brush grabs every lash for separation
• Formula prevents clumps for smooth application
• Multiple coats possible without weighing lashes down

What role does the Grow-Lash Complex play?

The Grow-Lash Complex is included to support the appearance of fuller, healthier-looking lashes when used consistently. It’s formulated to condition and fortify the lash surface while the micro-fibers provide immediate cosmetic length. This combination is intended to enhance both instant look and cumulative results over time.

• Conditions lashes to reduce breakage appearance
• Pairs conditioning benefits with visible lengthening
• Designed for everyday use as part of a lash routine

How intense is the Extreme Black shade and what is the tube size?

Shade 003 Extreme Black delivers deep, high-contrast color that amplifies lash visibility against any skin tone. The compact 0.33 oz tube is travel-friendly and easy to store in a makeup bag or purse. Despite the small footprint, the formula provides multiple uses and buildable coverage.

• 003 Extreme Black for high-impact pigment
• 0.33 oz travel-ready tube
• Suitable for layering from natural to dramatic looks
