Getting the Most Out of Your Adhesive

Getting the Most Out of Your Adhesive

Previously, we featured detailed information on the main ingredient in lash adhesive, cyanoacrylate, if you missed it read here. In continuing education about cyanoacrylate, we wanted to focus on how to best use adhesive based on an understanding of cyanoacrylate’s chemical properties.


During the application process fumes are given off as the adhesive cures. Many clients experience some type of irritation to these fumes, similar to how you might experience irritations to paint if you were painting your home walls. These symptoms are temporary and improve with time. Few clients experience true allergies to the adhesive. Clients that have allergies to the adhesive should not continue receiving lash extensions for their safety. Irritations are much easier to treat and even eliminate.

To reduce this risk of irritation, the adhesive should only be applied in well-ventilated areas. Lash artists should work in rooms with open doors and windows. If applied in a small room, we suggest using a fan to help circulate and renew the air in the room. This is best for your comfort and that of your clients. It’s also best to use the least amount of adhesive as possible to limit the amount of fumes in general. This will also make for a more natural lash feel and increase flexibility.

Since cyanoacrylate cures with exposure to water (even the air holds water), it’s important to keep it fresh for best results. The adhesive should be replaced within 4 weeks of opening, because it polymerizes over time and creates an uneven consistency. If you are opening and closing the adhesive frequently, it may need to be replaced even more frequently depending on use and exposure to water. This could vary by humidity as well.

Unopened adhesive has a shelf life of 12 months. It's critical that unopened bottles of adhesive are stored in the fridge or in an air-tight container, free from extra moisture. 

PRO TIP: Write the dates you purchase and open your adhesive bottles to ensure product quality and consistency.


Cyanoacrylate has an exothermic reaction with natural fibers, which means it releases a lot of heat! For this reason, cyanoacrylate should never be applied with cotton, leather, wool, or other natural fibers. This heat can cause serious burns and possibly even catch on fire. Yikes! Lash artists should NOT use cotton swabs. If something needs to be used during the application process, we recommend using micro swabs or disposable lip gloss applicators. Micro swabs or lip gloss applicators can also be used after the application process for makeup application including eyeliner and eyeshadow.

Cyanoacrylate is very effective and safe when used properly by a trained lash artist. Following these guidelines will help your clients enjoy their lashes and have a safe experience.
