What Causes Lash Allergy or Lash Allergic Reaction?

Eyelash extension allergies may be triggered by your body’s hypertensive reaction against any type of chemical cosmetic products. To be fair, lash allergies aren’t anyone’s fault, simply put allergy is a reaction of the body when it "does not like" something.

Most arises from the lash adhesives. In the adhesive, there is a chemical called cyanoacrylate and carbon black. Cyanoacrylate is a bonding chemical that gives the adhesion to the glue. Carbon Black is the black color of the glue. All eyelash extension glue has about 90% or more of Cyanoacrylate. Sensitive glue has less percentage of Cyanoacrylate. Therefore, the adhesion or retention is less than normal glue in this aspect (lashes shed faster because the bonding is not as strong.)

Though there is no direct glue being dropped in your eyes (it might feel like it due to the stinging). It is actually the VAPOR of the glue is what, can trigger your allergy if you are sensitive.

What To Do with Lash Allergy or Lash Allergic Reaction:

  • Remove the allergen - meaning you must remove the lashes altogether. This means your body does not "like" what you are putting on and sadly, you may not be able to wear lashes.

  • Putting rewetting eye drops to help ease the eyes

  • Rinse or wash your eyes often

  • If you don't have any allergy to anti-histamines, over the counter Benadryl may be a good option to help the body fight it.

  • Avoid wearing eye makeup

  • Apply cold compress

  • Avoid touching the eyes with your hands/fingers, you could be transferring germs.

Symptoms usually subside within 24-48 hours. If they persist even after you have removed your lashes, contact your optometrist. They may recommend: a prescription eye drop, ointment or oral anti-histamines.


This can also be the case where your body accumulates or getting exposed to Cyanocrylate overtime, it finally "react" to it. In this case, we may need to take the above actions by removing all the lashes. In other case, clients still wish to wear lashes and willing to take the risk. We would need to take a slower approach, one step at a time:

  1. Switch you to sensitive glue. Rinse your lashes after the application to clean any residue of glue vapor. Your lash retention may not be the greatest.

  2. If you are doing better, we can get you back to normal glue and still rinsing your lashes at the end of the application. Your lash retention may not be the greatest but will be better than option #1.

  3. If you are doing better after the above step for a while, we may be able to get you back on track. But your body needs to find time to adjust itself to.
