REVLON ColorStay Xtensionnaire Lengthening Mascara + Lash Serum, 201 Blackest Black — Tapered Brush, Pro-Vitamin B5

Revlon ColorStay Xtensionnaire is a dual-action mascara and serum that lengthens lashes up to 2X with a tapered brush and Pro Vitamin B5 for nourished-looking lashes.

This product combines a conditioning lash serum with a buildable mascara formula to create extension-like length and lasting wear. Lightweight flexi-polymer fibers cling to each lash while Adapti-Flex Technology helps the finish remain flexible and comfortable for up to 24 hours. The tapered brush reaches inner and outer corner lashes for definition, and the serum-infused formula supports lash condition over time without feeling heavy.

How does this product give longer-looking lashes without false lashes?

The mascara deposits ultra-fine fibers and defines each lash from root to tip to visually extend length, while the tapered brush separates and targets short hairs. Layerable pigment lets you build dramatic length or keep a natural look.

• Flexi-polymer fibers create extension-like length
• Tapered brush coats inner and outer lashes precisely
• Buildable formula for natural to dramatic results
• Smudge-proof finish for long-lasting definition

Will this mascara also improve lash condition?

Yes — the formula is infused with Pro Vitamin B5, a conditioning ingredient that helps maintain lash moisture and resilience over repeated use. While it’s not a medical treatment, regular application can help lashes appear healthier and less brittle.

• Serum-infused formula targets lash conditioning
• Pro Vitamin B5 helps maintain moisture and manageability
• Lightweight texture avoids flaking or weighing lashes down
• Suitable for daily use alongside other eye makeup

How does the tapered brush and Adapti-Flex Technology affect wear?

The tapered brush is designed to capture short corner lashes and separate strands for a defined, elongated silhouette. Adapti-Flex Technology keeps the finish flexible so lashes move naturally and resist cracking while maintaining hold for up to 24 hours.

• Tapered shape reaches tiny lashes at corners
• Brush design prevents clumping while adding volume
• Adapti-Flex provides flexible, long-lasting wear
• Smudge-proof, transfer-resistant performance

Is the shade suitable for intense, everyday looks?

Shade 201 Blackest Black delivers rich, deep pigment that reads bold on all skin tones while remaining versatile for daytime or evening looks. The formula layers evenly so you can go from subtle definition to dramatic impact without uneven patches.

• Deep black pigment for strong contrast and definition
• Even application prevents streaks or patchiness
• Works under or over lash primer products if desired
• Pairs well with liners and eyeshadow for complete looks

Who is this for: Revlon ColorStay Xtensionnaire is ideal for anyone seeking noticeable length without falsies—people who want buildable drama, long-wear performance, and a mascara that also supports lash condition. It suits daily users who favor smudge-resistant, flexible wear and beauty lovers wanting a tool that defines tiny corner lashes and creates a lengthened lashline. If you want a trusted, award-recognized (2024 SELF Health Beauty Awards) mascara that doubles as a conditioning serum, this product fits well into routine makeup and lash-care habits.
