Zelyno 2 in 1 Eyebrow Pen

The Eyebrow Pen is designed for all skin types, including sensitive skin. The product page lists it as suitable for combination, dry, normal, and oily skin.
However, the product contains Propylene Glycol and Methyl Benzoate in its formula, which can potentially irritate sensitive skin in some people. If you have very sensitive or reactive skin, I'd recommend testing it on a small area first or consulting the manufacturer to confirm it's right for your specific skin concerns before full application.
Customers generally report easy application and natural results, though individual reactions may vary.

The Zelyno Eyebrow Pen does not come with a sharpener. It's a liquid/gel-based pen with a dual-ended design (4-fork tip and precision brush tip), so sharpening isn't needed.
The product comes in a blister pack with just the pen itself. Since it's a liquid formula, just keep the cap tightly sealed when not in use to prevent it from drying out.

The zelyno Eyebrow Pen is designed for up to 24 hours of wear, but real-world longevity depends on your usage and skin type.
Customers report mixed results:
•
With normal use, one pen typically lasts 2-4 months before you need to replace it
•
All-day wear is the typical claim — it stays on through daily activities, though some customers note it needs touch-ups after 12-16 hours
•
Longevity concerns: A few customers mention the formula can dry out inside the pen if the cap isn't kept tightly sealed when not in use, so proper storage is important to extend the pen's life
Pro tip: Gently shake the pen before each use (as stated in the directions) to keep the formula active and prevent it from drying up.

Real customer feedback:
Customers consistently praise how natural it looks and how it fills in sparse areas beautifully. Most say it lasts all day, though keep in mind it may sweat off during heavy outdoor activity — pairing with a brow setting powder helps if that's a concern for you.

Yes. The fine tip can add subtle strokes around sparse-looking hairline areas. Apply sparingly and choose a shade that closely matches your roots.
