Why Is the Choice of Glue So Important for Lash Extensions?

Not all glues are created equal, and each has unique properties that can affect the final outcome of your lash extensions.

The wrong glue can cause many problems, including poor retention, irritation, and even allergies.

Poor retention can lead to lashes falling out prematurely, which can be frustrating for both clients and lash techs.

The right glue, on the other hand, can make all the difference in achieving a beautiful set of lashes that last for weeks.

A high-quality glue can improve retention, reduce irritation, and ultimately lead to happier clients.

It's important to note that not all glues work for everyone. Factors such as humidity, temperature, and the client's natural lashes can all affect how well a glue performs.

That's why it's crucial to experiment with different glues and find the one that works best!

What Should You Know About the Ingredients in Lash Glue?

As mentioned earlier, most lash glues contain cyanoacrylate, a quick-setting adhesive that is the main ingredient in superglue.

The ingredient is what allows lash glue to bond quickly to your natural lashes and hold the extensions in place.

However, cyanoacrylate can also cause irritation and allergic reactions in some people.

If you have sensitive eyes or a history of allergic reactions, choosing a lash glue specifically formulated for sensitive eyes is important.

Additionally, lash glue may contain other ingredients like hydroquinone, which helps keep the glue in a liquid state, and carbon black, which gives the glue its black color.

Some lash glues may also contain formaldehyde, a preservative that can cause irritation and allergic reactions in some people.

Eyelash Glue Buzzwords

When it comes to eyelash glue, there are a few buzzwords that you'll want to keep in mind as you search for the perfect adhesive.

Here are some of the most important terms to know:


Formaldehyde is used to produce cyanoacrylate adhesive, but it dissipates during manufacturing, leaving no trace in the final product.

Although a minimal amount is released as a natural byproduct during the adhesive's curing process, it's not at concerning levels.

It's good practice for lash artists to wear protective gear, like the Lace Carbon Filter Mask, and maintain well-ventilated workspaces to filter out VOCs.

It's all about creating a safe environment.

And for clients, a piece of advice: always communicate with your lash artist. Inquire about the adhesive they're using and gauge their understanding of it.

Remember, it's your face's delicate area in question. So, it is crucial to ensure that the person handling the chemicals knows their stuff.

Medical Grade

The term "medical-grade" in the context of cyanoacrylate adhesive can be misleading, as there's no official standard for this label.

Eyelash glues, especially those containing cyanoacrylates like Ethyl and Methyl Cyanoacrylate, are produced under strict conditions.

Though cyanoacrylates can cause skin adhesion or irritation, they possess medical benefits when used correctly.

For instance, in 2002, the US FDA approved Indermil®, a medical device for the closure of skin wounds that contains Ethyl 2-cyanoacrylate, confirming it doesn't sensitize the skin.

However, just because a product claims "medical grade" doesn't guarantee higher quality or safety.

Lash techs and aspiring DIY artists should use these adhesives carefully, ensuring well-ventilated spaces and wearing protective gear.

On the other hand, clients are encouraged to consult professionals and conduct thorough research before undergoing treatment.

Retention refers to how long the eyelash extensions will stay in place.

A good adhesive should provide a robust, long-lasting hold without damaging the natural lashes. Look for a bond with a retention time of at least four weeks.

Are There Natural or Hypoallergenic Alternatives Available?

Natural and hypoallergenic alternatives are available if you have sensitive skin or are concerned about the harsh chemicals found in traditional lash adhesives.

These alternatives are perfect for anyone who wants to avoid irritation or allergic reactions.

Natural Lash Adhesive

One option is using a natural lash adhesive made from water, beeswax, and plant-based resins.

These adhesives are gentle on the skin and eyes and are perfect for clients who want a more natural look.

However, they may not be as strong as traditional adhesives and may not hold up as well during physical activity.

Hypoallergenic Lash Adhesive

Another alternative is to use a hypoallergenic lash adhesive.

These adhesives are formulated to be less irritating to the skin and eyes and are perfect for clients who have had allergic reactions to traditional bonds.

They are also great for clients with sensitive skin or eyes.

Adhesive Issues That Can Lead to Bad Retention

Here are some common adhesive issues that can lead to bad retention:

Inappropriate Adhesive Consistency

Again, not all adhesives are created equal. Some are thicker, while others have a more watery consistency.

It's crucial to choose the right consistency based on the lash artist's speed and the client's needs.

Incorrect Adhesive Curing

The conditions under which the adhesive cures matter. Humidity and temperature can affect the adhesive's performance.

If the room is too humid or too dry, the glue might not bond correctly.

Old or Expired Adhesive

Just like any other product, lash adhesives have a shelf life.

Using an old or expired adhesive can result in weak bonding, making extensions fall out sooner.

Not Enough Adhesive

If a lash artist uses too little adhesive, the bond between the natural lash and the extension might not be strong enough, leading to poor retention.

Overuse of Adhesive

On the flip side, using too much adhesive can cause clumping. This not only looks unappealing but can also cause lashes to stick together, resulting in lash loss.

Remember that different lash glues come with varying strengths and drying times.

Whether you're a seasoned lash tech, a newcomer to the field, or someone attempting DIY lash extensions, safety should always be your top priority.

So, regardless of the adhesive you select, be sure to adhere to the correct application techniques.

Lash extensions can be a fun and glamorous addition to your beauty routine, but it's important to use them responsibly and with care.
