IS IT FRESH? DOES EYELASH GLUE EXPIRE?
As lash artists we have all had this thought – is this lash adhesive fresh or is it time to toss it in the trash? Can glue expire?

HOW LONG DOES LASH GLUE LAST?
The lifespan of lash adhesive can vary depending on the formulation and the manufacturer’s guidelines. Generally, an unopened bottle of lash glue can last between 6 to 9 months from the manufacturing date. However, the expiration date drops to 1-2 months once the glue is opened. This timeframe is crucial as the glue’s bonding strength diminishes over time, affecting the durability and appearance of the eyelash extensions.
We are dedicated to offering only fresh lash adhesive, ensuring every client enjoys the cleanest and most reliable bonding experience.
HOW SHOULD LASH ADHESIVE BE STORED?
Your glue can show you an excellent performance for up to 2 months if stored properly. Proper storage is paramount to extending the life of lash glue. It should be kept in a cool, dark place in upright position. Keep it away from direct sunlight, heat and moisture. Some professionals recommend storing open bottles in airtight containers with silica gel packets to minimize exposure to humidity. Temperature fluctuations and exposure to air can compromise the glue’s effectiveness, so keeping it in a stable environment helps maintain its quality.
We have equipped each bottle of glue with an exclusive temperature-controlled storage room.
CAN EYELASH ADHESIVE GO BAD?
Now, let’s answer the popular question: does lash glue expire? And the answer is – YES! Eyelash glue is susceptible to degradation over time, with factors like air, moisture, and temperature playing significant roles in accelerating this process. The chemical composition of the adhesive changes once it starts to expire, leading to a decrease in its bonding ability. Therefore, understanding when lash glue expires and recognizing the signs of degradation is essential for anyone working in the eyelash extension field.
Signs Your Eyelash Extension Adhesive Has Expired
- Appearance Changes
- Color shifts (from clear blue/black to yellowish or cloudy).
- Visible separation, sediment, or clumps inside the bottle.
- Stringing becomes uneven or breaks easily when dispensing.
- Consistency Issues
- Adhesive becomes too thick or sticky, making it difficult to pick up.
- In rare cases, it may turn watery and lose bonding ability.
- Performance Problems
- Drying time changes:
- Slower – takes 3–5 seconds instead of 1 second.
- Faster – hardens instantly, making application difficult.
- Retention drops – extensions fall off much sooner than 4–6 weeks.
- Bonding strength weakens – lashes don’t adhere securely.
- Smell Differences
- Stronger or more irritating odor = breakdown of adhesive formula.
- Faint or missing odor + poor performance = expired ingredients.
- Packaging Clues
- Hardened glue around the nozzle.
- Bottle swelling, leaking, or unusual pressure release when opened.
