Cyanoacrylate in Eyelash Glue: Why do Some Clients Develop an Allergy?

As an eyelash stylist you already know that it’s super important to follow best safety practices for your clients. But sometimes, even when you do everything exactly right, a client may have a bad reaction to her eyelash extensions. In many cases, this is the result of an allergy to eyelash glue, and specifically to an ingredient called cyanoacrylate.

What Is Cyanoacrylate?

Besides being a total mouthful of a word, cyanoacrylate is an ingredient used in all eyelash glue, even those formulated for sensitive or allergic eyes. The reason it is used in all eyelash glue is because it provides the glue with its adhesive quality. Without cyanoacrylate, the extensions wouldn’t actually stick to your client’s eyelashes. Cyanoacrylate is very adhesive and it solidifies fast, which is great for eyelash extensions.

So, What’s the Problem?

For most of your eyelash clients, there is no problem with this ingredient. As long as the extensions are applied very carefully and the glue never gets in their eye, they will have no reaction to cyanoacrylate whatsoever. However, in rare cases clients develop an allergy to this ingredient. Sometimes they may have allergic symptoms the first time they get eyelash extensions, but in other cases they will develop the allergy over time and have to stop getting eyelash extensions.

If your client is allergic to cyanoacrylate, they will experience redness, itching, and bumps along the lash line shortly after receiving a set of eyelash extensions. Unfortunately, for this small percentage of clients, eyelash extensions are simply not a good option.

What can you do to minimize the development of a cyanoacrylate allergy?

  1. Mist the lash extensions with water throughout and after you apply the extensions.

  2. Encourage your client to wash their lashes and eye area with lash wash and water when they get home.

  3. Encourage your client to wash their lashes and eye area daily with lash wash and water.


Eyelash glue containing cyanoacrylate is very safe when used properly. While a small percentage of clients do turn out to be allergic, this allergy is not especially dangerous, and the side effects will go away quickly once the eyelash extensions and glue are removed. Be sure to always do a complete intake form with all new clients which includes a section for known allergies.

If you follow these tips, your lash clients will come back to you time and time again. For more tips on getting more clients, visit our blog.
