Does eyelash glue expire? How long does lash extension glue last, exactly? If you have these questions, we have the answers. As always, we’re here to share our wisdom and expertise with lash artists to make your lives that little bit easier.
Lash adhesives do have an expiry date. And there is a correct way to store them. This blog post will cover all of the important advice, as well as what happens if you use expired eyelash glue on clients (which, spoiler alert, is always a big no-no!). Most of all, we’ll cover how to get the most from your eyelash adhesive.
How long is lash adhesive good for?
Lash adhesive will last up to 3-6 months from the manufacture date if unopened and stored correctly, but when opened, it will last 4 weeks, if you’re using it on 4-6 clients per day.
The main ingredient in lash adhesive is often Cyanoacrylates, which means it can have quite a long shelf life - especially if stored correctly and when following the right instructions.
Our best-selling glue, JetSet Pro Lash Adhesive can last as long as 12 weeks if opened infrequently, but the more you use it, the faster it will need replacing. To make it easy to remember, all adhesives have the same storage rules…
The best way to store your lash adhesive
- Keep the bottle tightly closed and in an upright position
- Once opened, store in a cool, dry room (19 degrees Celsius is ideal!)
- Store in an airtight lash glue container for longer glue freshness
- See the bottom of the bottle for manufacture and expiry dates
- Do not store your lash adhesive in the fridge or freezer. This will cause condensation build-up which can shorten shelf life to under 2 weeks.
What are the signs that the adhesive should be replaced?
- Black carbon pigment separates and you can see the clear adhesive
- Lash adhesive becomes clumpy or too runny
- Glue becomes tacky even after a good few minutes’ shake
- If the glue is dried out and won't come out of the bottle
If any of these apply to your adhesive, then it’s out with the old and in with the new. After all, you don’t want to take risks using any expired products on your clients - why would you - as it will lead to poor lash retention and unhappy customers. On top of this, it increases the likelihood of a reaction. And the only reaction we want from our clients is a happy one!
Tips for using lash glue when applying eyelash extensions
- Cleanse first. Always be sure to wash the client's lashes before applying lash extensions.
- Prime properly. Use saline solution or, ideally, an alcohol-free lash primer. Lash primers that contain alcohol dehydrate the lashes and affect the lash glue setting time.
- Choose the right glue. Select a lash adhesive which matches your environment and level of skill. Never buy adhesive for masters if you are a beginner.
- Shake the adhesive. It’s essential to shake the adhesive thoroughly before use. Remove the glue cap and use an adhesive pin or lint-free tissue to cover the nozzle. Before treatment shake for at least 60 seconds.
- Pick your glue sticker or palette. Pay attention to where you place your drops of glue as different surfaces can make adhesive dry faster.
- Tailor how much you use. Adjust the amount of adhesive to the humidity of your room during the day. The colder the room the smaller amount of adhesive you must use.
- Keep the bottle clean. Wipe the glue nozzle after each use with lint-free glue wipes.
- Keep your glue drop fresh. Replace your lash glue drop frequently according to changes in humidity and glue drop consistency.
Why do you have to shake your bottle of lash glue?
You need to shake your bottle of eyelash glue so that the ingredients inside the bottle mix properly. Lash adhesive comprises several ingredients, and some of them are made up of pretty hard particles - so for the best results, you have to shake the bottle quite vigorously to mix the ingredients together. If you miss this step, you run the risk of your adhesive not performing and failing to properly attach the extensions to the natural lash.
