A Line So Sharp, It Feels Like a Filter

Users say it 'makes my eyes pop' and looks 'clean and professional' every single time, with no fuzzy edges or bleeding.

Finally, Eyeliner That Survives Your Day

It stays put through long hours, humidity, and even a workout. Reviewers note 'no smudging' and 'it's still perfect when I get home'.

The Control You've Been Missing

The brush 'glides like a dream' and 'is so easy to use,' even for beginners. It turns shaky hands into a steady line.

No More Irritation or Stinging

The gentle, fragrance-free formula means 'no burning sensation' for those with sensitive or contact lens-wearing eyes.

One Stroke, Full Opacity

The intense black pigment means you don't have to go over the line repeatedly. It's 'deeply black in one pass,' saving time and product.

A Wing That's Actually Even

The fine tip lets you draw a crisp, sharp wing. Users love that they can 'get a perfect flick' without struggle.

No More Midday Panda Eyes

The smudge-proof lock means you never have to check a mirror nervously. It 'doesn't transfer' to your eyelid or under-eye.

Feels Like Nothing On

Once dry, the flexible film doesn't feel tight or crack. It's 'lightweight' and you 'forget you're wearing it.'

2. **High-Purity Carbon Black Pigment** — 99.8% pure pigment, milled to 5 microns for a deep, matte black that doesn't reflect gray or shine under light.

3. **Quick-Dry Polymer Matrix** — Proprietary film-forming agent (Patent No. JP6582932B2) dries in 15 seconds, forming a flexible, water-resistant layer.

4. **Smudge-Proof & Transfer-Proof Formula** — Tested for 12-hour wear against humidity (85% RH) and sebum in clinical settings.

5. **No Common Irritants** — Free from fragrance, mineral oil, parabens, and alcohol. pH-balanced to match the skin's natural acidity.

7. **360-Degree Flexible Brush** — The nylon brush bends in any direction, allowing application at any angle without pressure.

8. **High-Capacity Ink Reservoir** — Holds 0.55ml of ink, providing approximately 6 months of daily use with two lines per eye.

10. **Ophthalmologist Tested** — Formula tested for safety under the supervision of ophthalmologists for use around the eye area.

1. Start with clean, dry eyelids. Primer is optional, as the formula adheres well on its own.

2. Hold the pen like a calligraphy brush, with the tip perpendicular to your lash line for maximum control.

3. For a precise line, use short, light strokes, connecting them from the inner to outer corner. The flexible brush follows your eye shape.

4. For a wing, use the fine tip to draw the outline first, then fill it in.

5. Let it dry for 15-20 seconds. It sets to a smudge-proof finish.

Timeline Expectations:

- **Day 1:** You'll notice the intense, jet-black pigment and how the brush 'glides' without skipping.

- **Week 1:** Your application time cuts in half as you master the brush control. No more midday smudges or flakes.

- **Week 2-3:** You achieve consistently sharp, defined lines every time, even on sensitive or oily eyelids. The 'easy to use' feeling becomes routine.

- **Week 4+:** This becomes your non-negotiable tool. You rely on its all-day wear, from morning meetings to evening out, without a single touch-up.

Born from a Japanese obsession with precision, UZU by FLOWFUSHI was created to solve a universal frustration: eyeliner that smudges, fades, or fails to deliver a sharp line. Our chemists in Tokyo analyzed over 200 formulas, rejecting common irritants and unstable pigments. They developed a unique, brush-tip applicator and a deeply pigmented, quick-drying ink that bonds to the lash line without tugging. Every batch is tested in our GMP-certified facility in Osaka for purity and performance. This dedication made it the #1 ranked liquid eyeliner in Japan's prestigious @cosme rankings for 3 consecutive years, a title voted by real users, not critics.

The UZU BY FLOWFUSHI Eye Opening Liner - Precise Japanese Liquid Eyeliner is formulated with a carefully curated blend of ingredients designed to deliver exceptional performance and user benefits. Key components include water and butylene glycol, which serve as solvents and humectants to ensure smooth application and prevent drying. The inclusion of acrylates copolymer provides film-forming properties, creating a durable, flexible, and water-resistant layer that adheres securely to the eyelid without cracking or flaking. Pigments such as iron oxides and carbon black deliver intense, long-lasting color payoff with precise definition. Additionally, ingredients like glycerin and panthenol act as moisturizing agents, helping to condition the delicate eye area and reduce irritation. The product also contains preservatives like phenoxyethanol to maintain stability and shelf life, ensuring hygiene and safety. This combination results in a liner that offers sharp, effortless application, extended wear without smudging, and a comfortable feel that caters to both aesthetic and practical needs.
