The quirky nature of eyelash extension glue

18 February 2020

I like to talk about glue: somewhat of a “punching bag” subject when it comes to eyelash extensions.

Misunderstood, glue is often blamed when eyelash applications go wrong, or when the client has an allergic reaction either during or after the session.

We are going to look at how it works, what it’s made of and how to take care of it so that we can finally make the best of it despite its quirks.

Better understanding of black and even clear glue will mean better usage.

Lash artists should keep in mind that, according to latest studies, glue is responsible for less than 3% of adverse reactions to lash extensions.


Eyelash extension glue is formulated with cyanoacrylate on one hand and pigment on another, which makes it various shades of black.

Cyanoacrylate comes in different grades of quality, ranging from super glue to sutures used in pediatric medicine for closing wounds.

There is methyl, ethyl, butyl and octyl cyanoacrylate.

The cyanoacrylate used by Misencil is close to medical grade and naturally meets the highest quality standards in the countries where we are represented.

To use it well, we need to know how it reacts and behaves when facing adversity!

Adhesive glue has specific requirements but not all types of glue are alike.

The air humidity levels and temperature at the salon or at home must be as much in line with the ideal storage conditions for your glue as possible.

I encourage you to purchase a hygrometer in order to be as precise as possible in your treatment room.

Here is a table that can help you choose your glues:

Storage is also very important because eyelash extension glue has very specific requirements.

Confronted with fluctuations in temperature, it will fight back and show its unhappiness with lower effectiveness, decreased adherence, and changes in texture, retention and even appearance.

At this point, you should not hesitate to change or replace it.


For a better understanding, let’s talk a little about polymerization.

In this chemical reaction, molecules combine or agglutinate to help harden your glue and finish its drying process.

Luckily, all our glues dry in two (2) hours.

This shows the importance of telling your clients about the necessity to avoid putting water in the eyes, exercising or watching romantic comedies for two (2) hours following the application of their eyelash extensions.

I remember a little anecdote: one of my clients tried going to a hammam two (2) hours on the dot after our session. I had warned her of the significant risk she was running of losing her extensions but received a message later that evening to tell me that her eyelashes were intact – to my own and my client’s great relief!

In your practice, drying with an air blower before and after the shampoo as well as after Balance 7 will help open lash scales and enable optimal adherence of lash extensions.

Nanomist at the end of application accelerates and completes drying by speeding up the agglutination process in the glue. It will also help disperse the fumes away from sensitive eyes.

So, now you know, in order to keep your glue at its best, know your environment and the adhesive that best suits your needs, storing it in optimal conditions and the most stable environment possible, giving your clients the right information and not hesitating to reach for a new bottle when you observe the slightest change.

Glue seems to be a popular subject in training so it must like the attention! I will go into more detail about storage in my next blog post: how to take good care of your favorite glues!
