Frequently Asked Questions

Q: Is this waterproof liquid eyeliner suitable for sensitive eyes or contact lens wearers?

A: This eyeliner is formulated for all skin types and features no high-concern chemicals. However, if you have particularly sensitive eyes or wear contact lenses, we recommend applying carefully along the lash line and avoiding direct contact with the eye. Always perform a patch test before first use.

Q: How do I remove this waterproof liquid eyeliner?

A: Due to its long-lasting, waterproof formula, we recommend using a dedicated oil-based makeup remover or micellar water to gently dissolve and lift the liner without rubbing or tugging at the delicate eye area.

Q: What is the silkworm eyeliner technique and can this pen achieve it?

A: The silkworm technique involves drawing a soft, slightly puffy line just beneath the lower lash line to make the eyes appear larger and more youthful. The 0.014mm ultra-fine nib on this pen makes it ideal for this precise, detailed application with full control.

Q: Does this eyeliner come in both black and brown shades?

A: Yes! This eyeliner pen is available in classic black and warm brown, so you can choose the shade that best complements your natural coloring or desired makeup look.
