Unopened: For optimal lash retention results, use your lash extension glue within 3 months of the purchase date. Ensure it's stored upright in a small airtight container, accompanied by oxygen absorber sachets. Keep in a cool, dry place or refrigerate.

Once Opened: To achieve the best bond strength and lash retention, use the lash adhesive within 1 month. It's advised to replace the adhesive every 30 days for peak performance. Avoid returning the opened adhesive to the fridge, as temperature changes can cause condensation to build up on the inside of the bottle, which will accelerate its degradation. Ensure the cap is on tight after each use.

Selecting the right lash adhesive depends on your working environment (temperature and humidity) and skill level. For instance, our Azure Low Humidity Eyelash Extension Glue is suitable for fast applications in low-humidity environments, while the Aquila Low and Medium Humidity Lash Adhesive offers flexibility with a slower setting time, ideal for those needing a more adaptable lash glue. For detailed guidance, refer to each product’s description, or read our comparison guide.

An opened bottle of LashJoy lash glue is effective for about 4-6 weeks, although we recommend replacing it every 30 days for the best results. Unopened eyelash extension glues last up to 3 months if stored correctly, ideally in the fridge. However, once opened, avoid refrigeration to prevent condensation inside the bottle, which can degrade the lash adhesive. Regularly replacing glue (every 30 days) ensures optimal lash retention.

Stringy or gluggy lash glue often results from moisture exposure or incorrect storage. Humidity, leaving the cap off between uses, not “burping” the bottle, or frequent opening can cause eyelash extension adhesive to thicken. Always store the glue upright, tightly sealed, and in a dry place. Read more on storage tips to keep your glue fresh.

To prevent air bubbles, “burp” your lash glue bottle after dispensing by gently squeezing it to release trapped air, then wipe the nozzle with a lint-free wipe. This helps maintain smooth application and keeps your eyelash extension glue fresh longer. Be sure to place the cap back on tightly after each use.

Using the correct amount of lash adhesive is essential for optimal retention. Dip the extension lightly to coat just the base with lash glue. Avoid using too much, as it can weigh down natural lashes or affect retention. Ensure a bead at the base of the extension and never wipe excess glue on pads; instead, re-dip at the correct speed. Watch our YouTube tutorial for a demonstration.

Removing lash glue should be done by a trained professional to avoid damage. Use a specialized eyelash extension glue remover, applying gently with a microbrush or cotton swab. Self-removal may cause severe damage or blindness. Avoid pulling extensions, as this can harm natural lashes and may take months to recover. We recommend having lash glue removal done by a qualified artist.

LashJoy glues are crafted for excellent lash retention, typically lasting 6-8 weeks when applied correctly. Retention depends on factors such as humidity, application technique, natural lash shedding, and client aftercare routines. With proper use, eyelash extension glues can support a full lash growth cycle. For tips on optimizing lash retention, read our blog.
