When it comes to eyelash extensions supplies, lash artists know that quality adhesive is the one of the factors in being able to give a client a beautiful look that lasts. Have you taken the time to learn how the adhesive works and what you need to take into consideration to make it work? When you understand just what is in your adhesive and why, your application process will be seamless time and time again.

Today, we’re going to tackle how adhesives work and why it really is you and not the adhesive.

First, the active ingredient in adhesives designed for eyelash extensions is a form of cyanoacrylate. Cyanoacrylate starts off as a liquid, and when exposed to moisture, it cures into a solid form. Simply put, cyanoacrylate is what causes the extensions to adhere and bond with the natural lash. Get why it really is you and not the adhesive? Adhesives are rarely faulty as they're literally formulated to adhere. This is why it's important that we understand the prep work that goes into our clients' lash line as well as take note as to our work environment in order to create the most optimal bond.

Most lash adhesives contain up to 90 weight percent cyanoacrylate thus making it the most important ingredient to understand. Cyanoacrylate is composed of monomers or single molecules in liquid form. When these single monomers are exposed to moisture they attach to one another to make a polymer. This process is known as polymerization. When monomers become polymers, cyanoacrylate turns into a solid. Moisture triggers the cyanoacrylate reaction. We [lash artists] commonly describe this process by saying that the adhesive is drying or curing. 

Stay tuned for the next part of our series as we dive into what's in our ingredient list and why.
