innisfree Powerproof Brush Liner

Active Complex is the hero active in this formula, delivering targeted results with every application.

The value of a powerproof liner lies in adhesion and set time. When a liquid eyeliner forms a more stable film after application, it is less likely to shift, fade, or transfer quickly during blinking and normal daily movement. A brush format supports that wear profile by applying product in a controlled, even layer instead of leaving thick patches that can crack or break up. Close adhesion at the lash line is especially important because the eye area experiences frequent motion, moisture, and oil. In practical terms, that means the line can stay neater for longer when the formula sets well and the product is placed precisely. The overall performance is a combination of two factors: a brush that helps control placement and a finish that holds shape after drying. For users who prioritize cleaner wear over a softer diffused effect, that makes this style of liner especially useful.
