How Weather Affects Your Eyelash Extension Adhesive

How Weather Affects Your Eyelash Extension Adhesive

Summer is in full swing and boy is it heating up!  In the last blog I discussed tips to make sure your eyelash extensions get the extra TLC they need in the warmer months but keeping those beautiful eyelash extensions in tip-top shape actually starts with your adhesive.  Humidity and high temperatures are enemies of eyelash extension adhesives so what can you do to protect it from being damaged in the summer months?  Below are three ways to make sure your eyelash extension glue consistently provides you and your clients with reliable and quality results despite the warmer temps.

  1.  Keep your adhesive in a cool, dark place.  It is best to use your adhesive in a stable environment and avoid temperature fluctuations. If it is too hot or too humid, the viscosity and adhesion can be altered.
  • The best temperature for eyelash extension adhesive is between 64-77 degrees Fahrenheit.  Storing in a dark drawer with dry rice or a silica pack will preserve the freshness and keep moisture away from your adhesive.
  • Optimal humidity when working with your adhesive is between 50-60%. Purchasing a digital hydrometer for your working space is highly recommended.  The hydrometer monitors the humidity in the room and gives you a digital reading.  You can purchase one on Amazon for around $10.  If your space is on the dryer side, or you work in dryer climate, then purchasing a humidifier or diffuser for the room is a MUST.  These are great because it pumps moisture into the air, providing you with optimal humidity.  I like to add a few drops of essential oil to the water so the room smells pleasant, as well. If you work in an area that is very humid, then you can purchase a dehumidifier, which balances the humidity by removing some moisture from the air.
  • When ordering your adhesive online, I suggest checking the tracking and leaving a note for the delivery person to keep it out of direct sunlight once it is dropped off.  Being left out in the sun or heat will damage the adhesive. 
  • Oxygen can diminish the life of your adhesive.  Exposing your adhesive to too much oxygen alters the viscosity, (thickness), and essentially makes it go bad.
  • Keep the lid on tightly when you are not using it.  Leaving it opened for a long period of time, or frequently opening and closing it, exposes your adhesive to oxygen which will make it thick and gummy.  It is important to keep as much oxygen out as possible in order to prevent your adhesive from losing its super powers.
  • Replenish your adhesive as needed.
  • The shelf life for adhesive after being opened is 6 weeks, unless you notice it getting tacky/gummy before then.  This means, you should be replacing your adhesive bottles frequently to ensure they are always fresh.
  • Buying in bulk will save you time and prevent you from running out and scrambling to buy another bottle with short notice.  
  • To prolong the shelf life of your adhesive, you can store any unopened bottles in the freezer, (do not store in the refrigerator as this allows moisture to get in, and negatively impact the integrity of the ingredients).  Remove unopened glue from the freezer 4 hours before using it to allow it to reach room temperature.  Once opened, store as discussed in tip #1 above and avoid temperature fluctuations.


By following the tips above you should be able to sustain the recommended shelf life of your adhesive, and keep your business running without interruption, providing your clients with consistent and reliable work they can trust and be loyal to.


Happy Lashing!
