How You AND We Take Care of Your Lash Extension Glue to Ensure Flawless Performance

We all know how important using the best lash extension glue is when it comes to getting the lash extension retention we and our clients dream of, but how do you know for sure that the glue you're buying is fresh?

Lash extension glue has a shelf life of only 6 months prior to being opened, which isn't really a lot of time in the grand scheme of things, so it's really important that you're able to keep track of when your glue will be past its best, and keep your stock in rotation accordingly. So, how do you know your glue is fresh, and what do we do to make sure it arrives to you in perfect condition? 

How Can You Tell if Your Lash Extensions Glue is Fresh?

All London Lash glues have a DOP stamped on the bottom of the bottle and/or on the aluminium pouch that the glue arrives in. The DOP is the date of production, ie. the date the glue was made and bottled.

From this date, you have 6 months to use your glue, as long as you store it properly (we'll get to that a minute!)

If you buy more than one bottle of glue at a time so as to never be without, make sure you're paying attention to the DOPs of each so that you are able to rotate your stock effectively. 

How Can You Get the Best Out of Your Glue?

When you open your glue, take a piece of tape and stick it to the back of the bottle with the date that you opened it written on it. Depending how much you open your glue, we recommend swapping your bottle every 4-8 weeks – the more you open it, the more air it will be exposed to, and by extension, the more moisture it comes into contact with. More moisture = faster curing, so take care to replace your bottle every 4 weeks if you open your bottle a lot to ensure your glue is fresh and your retention is consistently great.

Make sure you are storing your glue properly. You should be keeping your glue somewhere cool and dry, away from sources of heat and direct sunlight. This means in an airtight container, not in the fridge, and with the lid screwed on tightly.

How Do We Keep Your Lash Glue Fresh?

We order a new batch of glue every month, meaning that whenever you buy your lash extension glue from London Lash, it has plenty of life left in it. We also take care to rotate our stock, so that you can be sure that any glue you buy has at least 4 months left in it, if not the full 6 months. 

After bottling, our glues are sealed in a film to keep any potential air out, and then we go ahead and pop it into an aluminum pouch with a silica gel packet – while we can't always control the temperature, we make absolutely certain that no moisture is getting to your glue at all! 

When your glue is with us, it's kept in a temperature controlled environment in the cooler part of our warehouse, and while we can't do much about the temperatures while it's on its way to you, having a warehouse in the US certainly helps to reduce the time that it's more likely to meet some changes in the temperature.

Had Your Glue for a While? It May be Time to Swap it if...

  • You don’t hear movement when you shake the bottle
  • Despite shaking well, the lash adhesive is still grey and separated when you dispense it
  • The glue is stringy when you dispense it
  • The glue is stringy when you pull a lash from it (this can also happen if the glue dot has been on your jade stone for a long time, so make sure you’re dispensing a new drop every 15-20 minutes) 
  • There is white residue on the adhesive around the nozzle (this means that the nozzle has come into contact with moisture and shock polymerized - this is largely due to the nozzle not having been cleaned properly, and the lid not being put back on tightly enough after use. This doesn’t necessarily mean that the glue inside the bottle will be unusable but if moisture can get to the nozzle, it can get to the glue, so use with caution!) 
  • Lashes don’t last, or they brush off during or at the end of the set (this can also be due to the lash adhesive working too rapidly, either due to room conditions or because it is a very fast glue, like Power Bond, when something more gradually drying like Lady Bond would be a better fit for you - check these factors too, as it may not be the glue’s fault!) 
  • It is more than 6 months old according to the DOP on the bottom of the bottle
  • It has been open for more than 6 weeks
  • It has been left out on your trolley, on a windowsill or above a radiator instead of somewhere cool in an airtight container.

While lash extension glue can often be one of the trickier parts of your lash extension kit to get right, you can save yourself so much hassle and worry simply by taking proper care of your glue.
