Brand note

Sacheu is best known for its peel-off lip liner stains, which creators either love for their all-day wear and natural tint or find gimmicky and hard to apply. The formula holds up through eating and drinking, but the application requires patience and precision. The brand also makes a thin, blendable liquid contour and a brow/freckle tint, but the lip liner is the clear anchor — just know it's polarizing.
