Types of Extension Glues

Cyanoacrylate-Based Glues

  • Cyanoacrylate-based adhesives reign supreme in eyelash extensions, offering unparalleled reliability.
  • They are lauded for their quick-drying properties and the formidable bond they create with natural lashes.
  • Two common variants exist within this category ─ Ethyl Cyanoacrylate, prized for its durability, and Methyl Cyanoacrylate, celebrated for its rapid drying time.

Formaldehyde-Free Glues

  • In the past, formaldehyde was a frequent ingredient in eyelash extension glues, but it has declined due to safety concerns.
  • The emergence of formaldehyde-free glues has provided a safer alternative, catering to individuals with sensitivities and health-conscious clients.

Medical-Grade Glues

  • Medical-grade extension glues are often recommended for individuals with sensitive eyes, allergies, or other health considerations.
  • These glues are meticulously formulated to be gentle on the skin and eyes, significantly minimising the risk of adverse reactions.

Latex-Free Glues

  • Latex-free glues are indispensable for clients with latex allergies.
  • They offer a robust bond without the looming threat of allergic responses, making them an ideal choice for many users.

Ingredients to Scrutinize


In your quest for the perfect extension glue, it’s imperative to scrutinise the ingredients listed on the labels. Familiarise yourself with the following standard components and watch out for their presence:


  • As previously mentioned, cyanoacrylate is the cornerstone of most eyelash extension glues.
  • It forms an exceptionally sturdy bond but can trigger irritation in some individuals, highlighting the importance of a preliminary patch test.


  • Historically, formaldehyde was employed in extension glues to expedite the bonding process.
  • Nowadays, it is widely regarded as a potential allergen and irritant, prompting many glues to be explicitly labelled as “formaldehyde-free.”


  • Latex is a known allergen and should be avoided if you have latex allergies.
  • Choosing latex-free extension glues is a prudent decision to prevent unwelcome allergic reactions.

Ethyl Cyanoacrylate and Methyl Cyanoacrylate

These two variants of cyanoacrylate are distinct in their properties, catering to varied preferences.

  • Ethyl Cyanoacrylate is celebrated for its durability, ensuring your extensions remain steadfast.
  • Methyl Cyanoacrylate, on the other hand, boasts swift drying times, streamlining the application process for experts and novices alike.

Critical Considerations When Selecting Extension Glue

When choosing the ideal extension glue for your lashes, several critical considerations can significantly impact the results and longevity of your eyelash extensions. Let’s delve deeper into these crucial factors:

Sensitivity and Allergies

Your sensitivity to the ingredients found in extension glues, such as cyanoacrylate and latex, should be the foremost factor influencing your choice. If you have a history of allergic reactions or known sensitivities, it is imperative to prioritise glues explicitly designed for individuals with delicate lash lines.

  • Formaldehyde-free glues ─ These glues are a haven for those with sensitivity concerns. They are formulated without formaldehyde, a known irritant, making them an excellent choice for individuals seeking a gentler adhesive option.
  • Medical-grade glues ─ Designed to cater to sensitive eyes and allergy-prone individuals, medical-grade glues are carefully crafted to minimise the risk of adverse reactions, ensuring a comfortable lash extension experience.

Drying Time

The drying time of your chosen extension glue should harmonise with your skill level and working pace. This factor can significantly impact the ease of application and the precision of your lash extension work.

  • Quick-drying glues ─ Some glues dry rapidly, almost instantaneously. While experienced technicians favour these for their efficiency, they may offer minimal adjustment time. Beginners might find such glues challenging to work with.
  • Slower-drying glues ─ Glues with a longer drying time provide greater flexibility, allowing you more time to perfect the placement of each lash extension. Novices may appreciate this extended working window to achieve precise results.

Bond Strength

The strength of the bond between the extension and your natural lashes is paramount in determining how long your eyelash extensions will last. A weak bond can result in premature shedding and shorter retention periods.

Ethyl Cyanoacrylate ─ This variant of cyanoacrylate stands out for its exceptional bond strength, delivering a resilient and enduring connection. Extensions affixed with Ethyl Cyanoacrylate will likely remain intact throughout your lash cycle, ensuring a longer-lasting look.

Retention Period

Different extension glues offer varying retention periods, ranging from a few weeks to several weeks. Your preference for how long your extensions will last should guide your glue selection.

Long-Lasting Glues ─ For those who desire extensions that endure an extended period, seek out glues boasting an extended retention period. These glues are formulated to withstand the rigours of daily life, maintaining their allure for weeks on end.

Technician Skill


The expertise and experience of your lash technician play an instrumental role in the success of your eyelash extensions. Always remember the value of open communication with your technician and seeking their expert recommendations.

  • Consultation ─ Engage in a comprehensive consultation with your technician before your lash appointment. Discuss your expectations, any sensitivities or allergies, and the desired look you wish to achieve.
  • Technician recommendations ─ Trust your technician’s recommendations regarding the choice of extension glue. They possess valuable insights into which glue type and brand will best suit your unique needs and goals.


Achieving enduring, captivating lashes extends beyond the initial application. Proper aftercare and maintenance practices are pivotal in ensuring your extensions retain their allure throughout their lifespan.

  • Aftercare education ─ Pay careful attention to the aftercare instructions provided by your technician. These guidelines typically include recommendations for cleansing, avoiding certain products, and scheduling maintenance fills.
  • Regular maintenance fills ─ To keep your lash extensions looking their best, schedule routine maintenance fills as your technician advises. These appointments ensure that any lost or grown-out wings are replaced, maintaining the fullness and beauty of your lashes.

Eyelash extensions possess the enchanting ability to elevate your natural beauty and bolster your self-assurance. However, achieving lashes that endure requires a meticulous assessment of eyelash extension glue & adhesive options.

You’ll emerge as a knowledgeable and discerning consumer by acquiring an in-depth understanding of the diverse types of glues available, discerning their ingredients, and appreciating the crucial factors to contemplate when selecting.

Remember, the choice of extension glue should harmonise with your individual needs, sensitivities, and lifestyle. Engage in meaningful discussions with a reputable technician, conduct patch tests if necessary, and invest in high-quality products to savour the delightful benefits of enduring, alluring lashes. With the perfect extension glue, your eyes will captivate the world with grace, style, and confidence, ensuring that your lashes truly last, leaving a lasting impression wherever you go.
