r.e.m. beauty At the Borderline Liquid Eyeliner — Teddy waterproof long‑wear felt‑tip precision liner

r.e.m. beauty At the Borderline Liquid Eyeliner in Teddy is a waterproof, long‑wearing felt‑tip liner that delivers inky, high‑impact color and precise lines for everything from everyday definition to dramatic stage‑ready looks.

This liquid eyeliner from r.e.m. beauty, crafted by Ariana Grande’s makeup line, combines a precision felt tip with a flexible, film‑forming formula to create crisp lines that resist fading, feathering, and smudging. The shade Teddy offers a deep, versatile tone that reads intense on the lash line but blends smoothly for smoked or graphic styles. Designed for makeup lovers who want reliable color payoff and control, this liner simplifies both quick daily routines and more elaborate eye art.

How does this liner give precise control for fine or bold lines?

The built‑in felt tip lets you draw single‑stroke lines with a steady flow of pigment, so delicate lashes and sharp wings are easier to achieve. The tip responds to pressure: light strokes make thin hairlines; firmer pressure builds thicker, bolder strokes.

• Precision felt tip for clean, exact edges
• Consistent pigment release for even coverage
• Responsive tip that adapts from hairline to graphic wing

Will it stay put throughout a busy day or during heat and humidity?

The formula is engineered to form a flexible film that adheres to skin and resists transfer, helping lines remain sharp under daily wear and in warmer conditions. While waterproof and long‑wearing, removal with an oil‑based or dual‑phase remover is recommended for gentle, complete removal.

• Waterproof formula minimizes running from sweat or light moisture
• Flexible film formers prevent cracking as skin moves
• Longwearing pigment reduces fading and smudging

How can I use Teddy to create both natural and dramatic eye looks?

Teddy’s rich shade is versatile: draw a thin line close to lashes for everyday definition, smudge lightly for a soft smoky finish, or build a bold wing for stage‑inspired drama. The formula layers smoothly, so you can intensify color gradually without patchiness.

• Thin lash‑line application for subtle definition
• Softly smudged edges for a smoky, diffused effect
• Layered build‑up for graphic, high‑impact styles

What makes this r.e.m. beauty liner travel‑friendly and easy to maintain?

The slim pen design fits comfortably in makeup bags and the felt tip stays ready for precise application on the go. The cap seals to protect the tip, and the formula’s consistency reduces the need for frequent touch‑ups throughout the day.

• Compact pen shape for purse or travel kits
• Secure cap protects the tip between uses
• Reliable pigment flow reduces reapplication needs

Who is this for: This At the Borderline Liquid Eyeliner in Teddy is ideal for anyone who wants dependable, inky color with sharp control—makeup beginners who need an easy, forgiving pen; beauty enthusiasts who build dramatic, long‑lasting looks; and performers who require waterproof definition that endures under lights and movement.
