Usage tips and suitability

This eyeliner is best for those who want precisely defined lashes with long-lasting color. Begin at the inner corner of the eye along the lash line and work the eyeliner outward. Position the brush close to the lash roots and use a gentle, fluid movement to follow the natural curve of your lash line. Safety first: test on a small area before first use to check for sensitivity, and avoid contact with eyes. If irritation occurs, discontinue use and consult a professional.

Tip: store the product in a cool, dry place away from direct sunlight to maintain pigment intensity and tip integrity. This shade is part of a line offering a bold, pigmented color option that suits a variety of skin tones and eye shapes.

Each application builds confidence as you get comfortable with the extra-fine brush, and you can easily switch from a precise line to a bold wing as desired.
