You know that annoying thing where lip liner looks like a sharpie line around your mouth? Sarah Sacheu built an entire company on fixing that — no fillers, just a blurring technique she kept posting on TikTok.
The trick went so viral that people started DMing her for the exact pencil she used. She wasn’t selling one. So she made her own — and it sold out in 48 hours.
Sacheu Beauty dropped the Lip Liner at $9. The claim that got me: “Smooths lip texture instantly.” I called bullshit. Then I tried it on my crusty winter lips.

It’s not fancy — and honestly, that’s the point. She swapped the drying polymers most liners use for oil-based waxes that stay put but never crack.
- Shea Butter: Softens the lip line so color blends, not bleeds
- Jojoba Oil: Stops that tight, shrink-wrapped feeling by lunch
- Vitamin E: Keeps the pigment from oxidizing into orange
- Candelilla Wax: Gives the blur effect without a sticky layer

First swipe feels like a crayon that’s been warmed in a pocket — creamy but with enough grip that it doesn’t slip into fine lines. The blur effect is real. It genuinely looks like I rubbed my lip with a filter.
Two weeks in, my only complaint: the shade range is small (six colors, all neutrals). But the one I wear, “Mauve Myth,” makes my pale lips look like I actually have blood flow.

My lipstick now lasts 6 hours instead of 3 because the liner acts like a primer. It didn’t erase my vertical lip lines — nothing will — but it stopped highlighting them.

It’s the only liner I’ve repurchased without being forced to. Not a miracle — just a smart fix for a stupid problem.
