Fumes Control: Which eyelash extension glue to choose?

best lash glue

Every lash artist knows that you can’t just take a lash extension glue, dip the extension into the glue drop and make it through the procedure to see a mesmerizing result in the end. Things are much more complicated here, and there is a big number of factors to be considered. One of them is the level of fumes in each particular glue, and what use experience it will bring to you if you purchase it. Let’s determine once and for all which individual lash glue will work well not only for you but also for your clients.

Understanding The Basics: What Are Eyelash Extension Adhesives

Eyelash individual glue belongs to the class of semi-permanent glues. Such adhesives are meant to hold the individual eyelashes for months and are unlike those that are skin-friendly. They can’t be used with strip and cluster eyelashes on bare skin. Thus, it’s required to avoid skin contact and not apply Cyanoacrylate-based glues to the eyelashes by yourself. Let’s dive deeper into the compound of semi-permanent adhesives we offer, which ingredients in eyelash glue you can find, and whats glue made of. Stacy Lash glue ingredients include the following components: 

Which ingredients are included in the eyelash extension adhesive? 


Cyanoacrylate is a strong component that ensures strong adhesion. That’s why semi-permanent glues for lash extensions promise long retention that lasts several weeks. 

There are several types of Cyanoacrylate:

- Methyl-Cyanoacrylate (alpha-cyanoacrylate, this component has no color and low viscosity. It’s the main component and it’s used for strong fixation) 

- Ethyl-Cyanoacrylate (polymerizes easily, this liquid is used to hold lash extensions for a long time, similar to methyl cyanoacrylate) 

- Alkoxy-Cyanoacrylate (better and more expensive than ethyl type, due to the low odor and low fumes level) 

- Methoxy-Cyanoacrylate (closely related to cyanoacrylate, it’s an odorless, non-blooming liquid with low toxicity, biocompatibility and adhesion power. 

But is there cyanoacrylate free eyelash glue? The thing is, there are really no existing glues that are completely hypoallergenic and don’t cause any irritation at all. During contact with bare skin, every glue can cause allergic reactions. In addition, the advanced formula of Stacy Lash glues is meant to reduce the number of fumes of Cyanoacrylate considering the individual needs of some clients. Unfortunately, it’s impossible to maintain good retention and fast drying time without adding the components that can potentially cause negative reactions. That’s why the procedure is performed in a well-ventilated environment with eyes tightly closed during the whole extension procedure and firmly taped down the bottom eyelashes. The fumes are still present, even though the level is low, the precautions need to be considered. 

Poly Methyl Methacrylate

This component strengthens the bond between the natural lash and extension. So-called Cyanoacrylate strengthener and helper.


Keeps your adhesive in a liquid state, and prevents it from hardening until you use it.

Carbon Black

It’s what makes your adhesive black. It’s simply a dye and transparent glues are designed without this particular component.

!Important! Make sure that you purchase latex-free eyelash glue, as it can cause allergic reactions sometimes. As lash artists, we are doing our best to perform a safe and comfy procedure for the customer, opting out for low-fume adhesives with no harmful components, so it’s important to choose quality products. 

Is Formaldehyde Harmful and What are its Risks?

Yes, formaldehyde is indeed a harmful element in your adhesive. This component is used in building and household manufacturing. It’s well known for moisture resistance and rigidity. So ensure that you buy a formaldehyde-free bottle of glue. Besides the risk of a reaction, such glue can cause an eye infection, or even worse, sometimes it leads to the loss of natural lashes. Even short-term exposure can cause pain, eye irritation, redness, and blurred vision along with severe watering. Also, it can cause sneezing and coughing, as it can irritate the throat, with nausea and headaches afterward. That’s why it’s important to use completely formaldehyde-free adhesives. 

Humidity, Temperature, and lash extension adhesive

How Does Humidity Affect Eyelash Extension Adhesives?

Humidity plays a key role in the life of your adhesive. It affects the drying time, and when within the recommended range, it prevents you and your client from developing an allergic reaction to lash extensions. 

How Does Temperature Affect Eyelash Extension Adhesives?

The temperature of your lashing environment is also important, as prevents the solidifying of your adhesive. Though, the humidity is surely a more important factor as the success of the lashing procedure mostly depends on a moisture level. 

How do Humidity and Temperature affect eyelash glue fumes?

Glue fumes are attracted to moisture, so if the humidity in the air is below the recommended level, adhesive fumes will seek moisture and affect the eyes, nose, and mouth. This way, the customer can develop a severe reaction, which is not good both for them and you. It's important to keep on top of your humidity level so that eyelash glue fumes bind to water vapor in the air.

What affects eyelash glue fumes more: temperature or humidity? 

As we have mentioned before, the humidity is a more important factor here. Moisture is a key point in successfully performed lash procedure, as when the moisture level is right, excess adhesive fumes bind to water vapor in the air. But if the moisture level is not within the right range, the fumes bind to the moisture present within the mucous membranes of the eyes, nose, and mouth.

What is the ideal temperature and humidity when using adhesive?

For most Stacy Lash glues perfect humidity is 50-70% and the temperature of 70-75 F. Though we have recently added a couple of adhesives for a wide humidity range (30-70%).

How do you stop eyelash glue fumes?

You might start wondering how you stop eyelash glue fumes. Well, it’s possible. Eyelash glue allergy won’t be a problem with these two new arrivals:



Both these products are used as parts of pre-treatment and aftercare and are designed to lower the chance of cyanoacrylate allergy and prolong retention. Eyelash booster is used to make your adhesive dry faster, and you still can use milder glues for sensitive eyes and they will dry at the speed that is suitable for you. A lash bonder is used as a final step of the lash procedure, it locks up the fumes, minimizing the chance of a reaction and eliminating the possibility of the shock curing during the first 24 hours. 


What is the best lash glue with low fumes?

Besides eyelash glue for sensitive eyes, which is already designed to have low fumes level, we offer two adhesives with a fast drying time, for advanced lash technicians. Both beginners and experienced artists can find their perfect glue in our range. The glue with the lowest amount of fumes is Lightning Speed (0.3 seconds), Evolution Advanced (1 second), and Stacy Lash Sensitive glue (5-6 seconds). Depending on personal needs and preferences every adhesive is safe to use if used properly. 

Can the client be allergic to lash glue fumes?

Red eyes after lash extensions and lash allergy can appear due to close contact with the ingredients. Cyanoacrylate allergy can be developed with time, but there are ways to protect your client from fumes and possible reactions. Fume control can be created with a fan or nano mister, or as an alternative, Extra Bonder from Stacy Lash. Bonder seals the bond between the adhesive and extensions, locking up the fumes. Thus, if the number of precautions is taken into consideration, the chance of a reaction will be very low. 

What are the side effects of eyelash extension glue? 

There are several common side effects of glue fumes:

  • Rash around the eye area
  • Itching
  • Swelling
  • Pain and eye-watering 
  • Burning

How to keep yourself safe from fumes? 

So, the main option is to opt out for a fan and nano mister to keep you and your customer safe from developing glue fumes reactions. It will add moisture if you feel the lack of it and protect the client's eyes together with the eye patches. The lash artist, in turn, will feel more comfortable as well, minimizing the level of fumes present. An innovative solution also known as an eyelash bonder helps the polymerization just perfectly, and you can forget about the harmful emission, as the cyanoacrylate will be locked. It will perform its main purpose - bonding the extension with the natural lash, but the side effect will be eliminated. Job done! You have nailed this lash set. 



Among the Stacy Lash glue range, there are several adhesives with different drying times, suitable for sensitive clients. We are constantly working on reducing the level of fumes so that our customers could be satisfied with the performance and get happy clients who never complain about eye redness after eyelash extensions.
