Slow-Dry Lash Glue for Training & Low Humidity — 2s Waterproof Black

How To Use

1. Prep — Cleanse natural lashes with Eyelash Primer for maximum adhesion
2. Shake — Shake the bottle for 30 seconds before use
3. Dispense — Place a small drop onto a jade stone or glue ring
4. Dip — Dip the lash extension base into the glue — use minimal adhesive for a clean bond
5. Apply — Place 0.5mm from the lash line and hold for 2 seconds until bonded
6. Refresh — Replace glue drop every 20–30 minutes for optimal performance
7. After use — Squeeze out excess air, wipe the nozzle clean, and seal tightly

Understanding Glue Performance — Temperature & Humidity

• Optimal conditions: 20–25°C temperature, 40–55% humidity — this is when curing speed and retention are at their best
• Retention is also technique-dependent: The lash artist's application speed, isolation quality, and placement all significantly affect how long the bond lasts — not just the glue itself
• High humidity: In humidity above 60%, this glue may cure too slowly and cause stickies — switch to 0.5s Glue for better performance
• Seasonal changes: Application in winter is naturally slower than summer due to lower temperature and humidity — this is expected and does not affect quality or retention
• How it works: Lash glue requires moisture from the air to cure. The 2s formula is calibrated for very low humidity environments where faster glues can feel unpredictable
• White residue on the bottle: Caused by moisture bonding with glue molecules on the bottle exterior during transport or storage in warm, humid, poorly ventilated conditions. Does not affect the glue inside. Keep the bottle in a dry, ventilated space to prevent this

Storage Instructions

• Store upright in a dry, ventilated space at 20–26°C
• Do not refrigerate — humidity inside the fridge is too high and will damage the glue
• Keep away from direct sunlight, air conditioning vents, and moisture
• Do not store near air conditioning airflow — temperature fluctuation and condensation can degrade the formula
• After opening: squeeze out excess air and wipe the nozzle clean after each use
• Opened bottle: use within 4–6 weeks for best performance

FAQ

Is 2s glue only for beginners?

Not exclusively — 2s glue is also great for experienced artists working in very cold or dry environments where faster glues cure too slowly. It's also the preferred choice for lash training academies where students need maximum time to focus on technique.

Why does my glue feel slower in winter?

Lower temperature and humidity in winter naturally slow the curing reaction — this is expected and does not affect quality. The 2s formula is already calibrated for lower humidity, so winter performance is generally consistent.

Is this lash glue good for humidity?

Best in low humidity (40–55%). In high humidity above 60%, the glue may cure too slowly and cause stickies — switch to 0.5s Glue for better performance in humid conditions.

There is white residue on my bottle — is it damaged?

No — white residue on the outside of the bottle is caused by moisture bonding with glue molecules on the bottle exterior, typically during transport in warm, humid, or poorly ventilated conditions. The glue inside is not affected. Store in a dry, ventilated space and the residue will not reappear.

When should I upgrade to faster glue?

Once you can consistently isolate and place lashes comfortably within 1–2 seconds, upgrade to 1s Glue or 0.5s Glue for better retention and efficiency.
