Cool for the Summer
Summer is a breath of fresh air after long cold winters. There are so many fun traditions and long pool days to look forward to during the summer. The hotter the day, the better, but this is not the case for lash adhesive.
Adhesive goes through a curing process when exposed to water (in the air, from the nano mister etc...). This process is quick and efficient, but it is also heavily temperature dependent. All opened adhesives should be stored at 68-72 degrees Fahrenheit, ALWAYS. This can be super challenging in hot summer months, but your adhesive will last longer and you will have better retention if this is followed.
Cyanoacrylate (the main ingredient in lash adhesive) cures fast, but when it is exposed to hot temperatures it cures at an uncontrollable rate. This curing is too fast for the molecules to form a secure bond between the lash extension and the natural lash. This will create retention issues and also make it difficult for lash placement.
Prior to opening the adhesive you can store it in the fridge for up to 12 months. The cold temperatures slow or stop polymerization, so it helps preserve the adhesive. Just like we put food in the fridge, so it will last longer. It’s the same concept of slowing down molecules making it harder for them to react. Allow the adhesive to warm to room temperature (68-72 degrees Fahrenheit) before opening. Wipe away any condensation that has gathered around the bottle as it can cause premature curing.
Keeping your open adhesives at 68-72 degrees Fahrenheit will be a game changer during hot summer days. What do you do to keep your adhesive fresh during the summer?
