REVLON Skinny Liquid Eyeliner — ColorStay Waterproof Black Out, Ultra-Fine 0.1mm Tip, Longwear

Revlon ColorStay Skinny Liquid Eyeliner in Black Out is an ultra-fine, waterproof liquid liner that delivers a precise, longwear black line with a 0.1 mm tip for streak-free definition.

For anyone who wants hairline precision and dependable all-day wear, this Revlon liquid eyeliner combines a super-slim brush point with a high-pigment, transfer-resistant formula. The design aims to produce crisp, consistent strokes—whether you’re creating a barely-there tightline, a defined lash-enhancing line, or a delicate cat-eye flick. Ophthalmologist-tested and formulated for sensitive eyes and contact lens wearers, it’s positioned as a daily-ready option with smudge resistance built into the ColorStay technology.

How does the ultra-fine tip help me get precise lines?

The 0.1 mm ultra-fine brush tip lets you draw very narrow, controlled strokes that follow your lash line without dragging or skipping. It’s small enough to create hairline detail yet stable enough for short winged flicks and tightlining between lashes.

• Ultra-fine 0.1 mm brush for micro-precision
• Smooth glide minimizes snagging and uneven color
• Great for tightlining, thin liner looks, or refined wings

Will this eyeliner stay put through the day and resist smudging?

The ColorStay longwear formula is engineered to resist fading, smudging, and transfer for extended wear. While individual wear time varies by skin type and conditions, the liner aims to hold a defined line throughout typical daily activities.

• ColorStay longwear technology reduces transfer and fading
• Waterproof and smudge-resistant for dependable wear
• High-pigment ink delivers even coverage in one stroke

How do I use this liner to make lashes look thicker or to create a cat eye?

For fuller-looking lashes, dot or make short strokes between lash gaps along the root to fill in sparse areas. For a classic cat-eye, draw a thin line from inner to outer corner, then extend a small flick and connect it back to the lash line for a clean wing.

• Dot between lashes to simulate denser lashes
• Draw tight to the lash line for subtle definition
• Build a feline flick by adding a short outward stroke and connecting it

Is this eyeliner safe for sensitive eyes and contact lens wearers?

This Revlon formula has been ophthalmologist tested and is marketed as suitable for sensitive eyes and contact lens users. As with any eye product, patch testing and avoiding direct contact with the eyeball reduces irritation risk.

• Ophthalmologist-tested for eye safety
• Formulated to be non-irritating for many wearers
• Recommended for contact lens wearers with standard precautions

Who is this for: Revlon ColorStay Skinny Liquid Eyeliner is aimed at makeup users who want razor-thin precision and lasting black color—makeup minimalists who prefer delicate lines, beauty enthusiasts who build layered eye looks, and anyone seeking an ophthalmologist-tested, waterproof liner for everyday wear. It’s ideal if you need a reliable, high-pigment liquid liner with a super-fine tip for clean, repeatable results.
