IT Cosmetics Superhero Liquid Eyeliner Pen Black — 24-Hour Waterproof, Brush-Hair Tip

IT Cosmetics Superhero Liquid Eyeliner Pen in Black is a waterproof, 24-hour liquid liner with a brush-hair tip and lash-loving ingredients that delivers a saturated, long-lasting line without smudging.

This precision liquid eyeliner is formulated to create intense, true black definition using a Triple Black Pigment Complex and Elastic Stretch No-Skip Technology. Designed to sit close to the lash line, the brush-hair tip glides smoothly for crisp, customizable lines while a mix of peptides, collagen, biotin and kaolin clay supports the look and helps control oil for cleaner wear. The compact 0.03 fl oz pen is travel-friendly and intended for everyday wear or special occasions when longevity matters.

How does the brush-hair tip improve application?

The brush-hair tip is engineered to mimic a fine artist’s brush, offering more control and a smoother stroke than many felt-tip liners. It resists fraying so each pass remains precise, whether you want a hairline thin flick or a bold cat-eye. Because it lays pigment close to lash roots, it reduces visible gaps and creates a seamless, lash-hugging finish.

• Brush-hair tip for variable line thickness from one tool
• Glides across lids with minimal skipping or tugging
• Delivers pigment close to lash roots for fuller-looking lashes

Will this eyeliner last through a long day or humid conditions?

The formula is built for extended wear and is described as waterproof with up to 24-hour performance. Its oil-absorbing kaolin clay helps the liner stay put in humid or oily conditions, reducing smudging and transfer. While individual results vary with skin type and activity level, the formula is designed to resist fading and maintain a deep black finish.

• 24-hour, waterproof formulation for prolonged wear
• Kaolin clay helps control oil and minimize transfer
• Triple Black Pigment Complex maintains intense color

What skin- and lash-friendly ingredients are included?

Beyond pigment and performance technology, the liner contains ingredients chosen to be gentle and supportive around the eye area. Peptides, collagen and biotin are included in the blend; these are commonly used in cosmetics to promote the appearance of healthier-looking lashes. The formulation balances performance with consideration for delicate eyelid skin.

• Peptides included to support lash-area conditioning
• Collagen and biotin help promote the appearance of stronger-looking lashes
• Kaolin clay manages excess oil for cleaner wear

How do I get the best line with this eyeliner pen?

Start with a light hand and glide the brush-hair tip along the base of your lashes from inner to outer corner. Apply gentle pressure for a thin line and increase pressure for a bolder stroke; the brush tip offers responsive control so small adjustments change the line weight. For winged looks, build up slowly and keep the pen angled slightly for a sharper edge.

• Begin at the inner corner and work outward for consistent pigment
• Light pressure = thin line; more pressure = thicker line
• Use a steady, slightly angled motion for winged styles

Who is this for: IT Cosmetics Superhero Liquid Eyeliner Pen is intended for anyone seeking a high-pigment, long-wearing black liner with precise application. It's suitable for beginners who want a forgiving brush tip and for experienced users who need reliable, smudge-resistant results for full days, active schedules, or event makeup. Those with sensitive eyes should perform a patch test first and discontinue use if irritation occurs.
