What Glue Is Used for Lash Extensions and Does Lash Glue Expire? Mish's Lash Adhesive Guide

Hello, I’m the CEO of Mish Esthetics, and I’m excited to share some key information about our professional products. Today, I’ve split this blog into two sections to answer two common questions: “What Glue is Used for Lash Extensions” and “Does Lash Glue Expire?” I hope this helps you feel more confident about choosing the best lash supplies for your business.
What Glue is Used for Lash Extensions
Many people ask, what glue is used for lash extensions? The answer is that our lash extension glue is specially formulated to work just like a strong, quick-bonding superglue. The main ingredient is cyanoacrylate, which polymerizes and cures into a plastic-like texture. This process ensures that the lash extensions stay securely attached to your natural lashes until the lash cycle is over.
Our glue is very different from adhesives used for strip or false lashes. Unlike strip lash glue—which sticks to your skin and lasts only a day or two—our extension lash glue is made exclusively for natural lashes. It contains ingredients like polymethyl methacrylate (PMMA) that create a firm yet flexible bond, making it the best lash extension glue for both safety and performance.
I must stress that this glue is only for natural lashes and should never touch the skin. There are DIY options or even other types of hair glue on the market, but these are not professionally recommended. Some nail salons, for example, may claim to offer lash extensions using cluster lashes with regular adhesive on the skin and lashes, which can be very painful, harmful, and uncomfortable. At Mish Esthetics, we use glue that is only meant for lash extensions, ensuring a safe and comfortable experience for every client.
Does Lash Glue Expire?

Now, let’s talk about another common question: does lash glue expire? Yes, like many products, lash glue does have a shelf life. At Mish Esthetics Salon, we are very committed to quality. We order fresh batch adhesives every other month to ensure our customers always receive premium lash glue for extensions.
If you have an unopened bottle of our adhesive, it can last more than six months when stored in a stable environment with controlled temperature and humidity. However, once the adhesive is opened, its exposure to humidity starts the clock on its shelf life. Typically, an opened bottle can last between four to eight weeks. The more frequently you open the bottle, the shorter its shelf life may become. For busy lash artists who are booked out three days a week, I recommend switching out your glue about every month. This way, you’re always working with fresh adhesive that guarantees optimal performance.
To make things even easier, our customers love our subscription service. It not only saves you 15% monthly but also automatically sends you a fresh supply, so you never have to worry about running out or using glue that has expired.
Thank you for being a part of the Mish Esthetics community. By understanding what glue is used for lash extensions and knowing does lash glue expire, you can ensure that you always use the right product for flawless and safe lash extensions. Happy lashing!
