Adhesive – Shelf life & storage

Storage and shelf life

Quick answer: Lash adhesive (cyanoacrylate) reacts with moisture. Correct storage prevents thickening, clogging and poor retention, and helps you get the best shelf life after opening.

Best storage practices (pro tips)

• Do not refrigerate: Never store eyelash extension glue in the refrigerator. Temperature swings can create condensation, and moisture can harden the adhesive.
• Store cool + dark: Keep the bottle in a dark and dry place at around 20°C (ideal range: 18–24°C).
• Use a dry container: Store in a thermopack with silica gel or a sealed jar.
• Moisture control option: A jar with rice can help reduce moisture exposure (rice absorbs humidity and helps keep the glue bottle dry).

Best working conditions (humidity + temperature)

• Best storage temperature: 18–24°C
• Best working humidity: 50–80%
• If room temperature is too low, the adhesive can take longer to cure. In that case, artists often use a Nano Sprayer to help manage curing and comfort.

Troubleshooting FAQ

Why shouldn’t I store lash glue in the fridge?
Fridges cause temperature changes and condensation. Moisture can trigger cyanoacrylate to harden and shorten shelf life.

My glue thickened or turned stringy. What does that mean?
Usually moisture exposure, age, or leaving the bottle open too long. Improve storage (sealed container + silica gel) and cap discipline. When this happens, it is best to dispose of the glue and purchase a new one. 

What’s the best way to store an opened bottle?
Keep it sealed, dry and dark (18–24°C). Store in a thermopack with silica gel or a sealed jar with rice to keep humidity away from the adhesive.

My room is cold and the glue cures slowly.
Warm the room if possible and keep within the recommended range. Many artists use a Nano Sprayer to support curing and reduce discomfort.
