What Is Puppy Liner?
Puppy liner is an eyeliner technique where the line extends downward at the outer corner instead of flicking upward, creating a soft, youthful, wide-eyed look.
Puppy liner originated in K-beauty as the opposite of a cat-eye wing. Instead of an upward flick that elongates and lifts the eye, puppy liner angles gently downward, following the natural curve of the lower lash line. The result opens the eye, makes it appear rounder and larger, and gives an innocent, approachable expression—like a puppy's soft, rounded eyes. The trend gained massive traction on TikTok and Instagram in 2024 and continues to be popular because it's universally flattering and works on all eye shapes, including hooded and monolid eyes where a traditional wing can be tricky.
Tips
- Start with a thin line along the upper lash line and extend just past the outer corner, angling slightly downward.
- Follow the natural curve of your lower waterline to guide the angle—don't go too steep or it'll look droopy.
- Smudge the line gently with a small brush for a softer, more natural effect.
- Brown or dark brown liner is the classic choice for puppy liner—it's softer than black and enhances the youthful vibe.
