r.e.m. beauty At the Borderline Eyeliner Marker — Midnight Black, Long-Wearing Waterproof Felt-Tip Liner

r.e.m. beauty’s At the Borderline Eyeliner Marker in Midnight Black is a precision felt-tip liquid liner that creates rich, waterproof lines for everything from subtle definition to dramatic graphic looks.

Delivering deep pigment and a marker-style tip, this eyeliner is built for controlled, single-stroke application that stays put through daily wear. The formula blends flexible film formers with a high-impact color base so lines look sharp and comfortable rather than stiff. Designed by r.e.m. beauty, the product aims to make both classic and creative eye styles easy to achieve.

How does the felt-tip design improve application?

The slim, firm felt-tip gives steady control so you can draw hairlike strokes or bold wings without tugging at the lid. Because the tip maintains its shape, it helps achieve consistent line width from the inner corner to the outer wing.

• Single-stroke pigment delivery reduces layering and touch-ups
• Firm yet slightly flexible tip adapts to lid contours
• Sharp point enables precise inner-corner and lashline definition
• Broad side of tip works for quick thick lines or graphic shapes

Will it last through everyday activities and light moisture?

The liner features a waterproof, long-wearing finish formulated to resist fading, feathering, and smudging during normal wear. While designed to stay in place during regular movement and humidity, removal with an oil-based or dedicated eye makeup remover is recommended.

• Water-resistant formula maintains color integrity over hours
• Flexible film formers allow the line to move with skin without cracking
• Resists transfer and smudging under everyday conditions
• Removes cleanly with proper eye makeup remover

What kinds of looks can I create with Midnight Black?

Midnight Black is a deep, inky shade suited to a wide range of styles, from subtle lash enhancement to dramatic cat eyes and graphic liner art. The pigment payoff supports everything from tightlining to bold, high-contrast shapes used in editorial or evening looks.

• Tightline and lash-defining micro-strokes for natural emphasis
• Thin lines for daytime polish or thick wings for evening drama
• Graphic shapes and precise accents for creative makeup ideas
• Layerable without flaking for built-up intensity

How should I integrate this liner into my routine?

Use the marker on clean, primed lids for best adherence; a quick base of primer or powder helps hold the line. Start with light, short strokes along the lashline, then connect and refine—clean up edges with a pointed cotton swab or concealer for crisply defined wings.

• Apply on a matte or primed lid for longevity
• Work in short strokes for even pigment placement
• Allow a few seconds to set before blinking heavily or layering other products
• Store tip-down to keep pigment flowing consistently
