all about eyelash adhesive

Every lash artists should be taught in depth all about lash adhesive, but sometimes it can be really overwhelming. In this blog we will be diving deep, but simple into lash glue terminology and further educating!

Cyanoacrylate - curing time

What is it?

Cyanoacrylate is a crucial component in eyelash extension adhesive. It is in all glues..

It gives lash adhesive it's curing property.

Cyanoacrylate is the substance that makes sure glue cures and holds for great retention.

carbon black

It's what makes the black color of the adhesive.

It is not in clear glue.

If your client has an allergic reaction to a black glue, it could be the carbon black they have an allergy too, as opposed to the cyanoacrylate, they could have an allergy test to determine what they're allergic too.


What is it?

The thinness or thickness of the glue.

The thinner the glue: the faster it cures.

The thicker the glue: the slower it cures.

A thicker adhesive is great for beginners.

Our Infinite Bond is perfect for beginners, with its 2-3 second curing time and thick viscosity, it leaves time to correct mistakes and perfect your sets!

latex free

What is Latex?

A natural rubber.

Some people have a latex allergy, which is why latex isn't in most lash adhesives anymore!

If your clients have sensitive eyes, latex free glues are your best bet.

POLYMETHYL methacrylate - Strength

What is it?

PMMA or poly (methyl methacrylate) is the means that creates the solid retention between the NL and extension.

Cyanoacrylate ensures the curing the adhesive PMMA provides a lasting adhesion.

humidity and room temperature

What is humidity?

The water vapour that is present in the air.

Why do they matter?

Adhesives are very fussy, you need to have the correct temp and humidity for them to perform to their best ability, invest in a hygrometer and you can tweak your room if need be.

When there is too much humidity the lash adhesive will dry too soon, which can result in retention issues.

Shock curing can also occur, this is a chemical reaction when your adhesive cures and dries too quick.

Too little humidity will slow down the curing process, taking you longer to do your sets and will cause stickies.

Fluctuation in your room temperature can cause your adhesive to change consistency and drying time

drying vs curing


The process of the chemical ingredients in the adhesive evaporating into the air which in turn makes the adhesive harden.

Drying is when the outside of the adhesive is hardened by the air.


The process in which the whole of the adhesive through to the centre of the glue hardens.
