How to Make Your Eyeliner Last All Day: Pro K-Beauty Tips

1. Remove Oil First: Dab translucent setting powder or a nude matte eyeshadow across the upper eyelid and lash line before drawing.
2. Fill the Gaps: Use a pencil liner (Lilybyred or CLIO Sharp, So Simple) to fill the gaps between your eyelashes (tightline).
3. Wing Precision: Switch to a brush pen (COSNORI or CLIO Pen Liner) to extend a clean flick from the outer corner of the eye following your natural eye shape.
4. Lock the Waterline: Allow the formula to set for 10–15 seconds before blinking or touching the eye area.

Frequently Asked Questions (FAQ)

• Q: How do I remove waterproof Korean eyeliners without irritating my eyes?
  • A: Because these formulas use strong film-forming silicone resins, standard water-based cleansers will not fully dissolve them. Use a biphasic lip-and-eye makeup remover (oil-water mix) or a cleansing balm, press a soaked cotton pad over the eye for 10 seconds, and wipe gently.
• Q: Why does my liquid brush pen sometimes dry out or skip?
  • A: Foundation, facial oil, and loose powder can build up on the micro-bristles. Gently wipe the brush tip with a damp makeup wipe or wet tissue to restore smooth ink flow.
