Lash Extension Adhesives: Glue Ingredients Your Tech Uses

Lash Extension Adhesives What Ingredients And Glues Your Lash Tech Uses

Eyelash extensions have seen a huge surge in popularity over recent years – and this is a trend that shows no signs of slowing down.

The rise of social media and Instagram means that more of us are chasing the perfect look for a selfie, and this includes the application of long, luscious lashes that really help our eyes to pop and stand out.

As amazing as lash extensions are you may be wondering what are the materials used by your lash tech to create that perfect look?

We have put together all you need to know about the eyelash extension glue ingredients your lash tech uses.

 

What Are Eyelash Extension Adhesives?

 

As we have discussed, eyelash extensions are created by bonding individual strands of synthetic fiber onto your existing natural eyelashes.

These fibers are then bonded together into one long strand, which is then attached to your natural eyelashes using a special adhesive.

There are two types of adhesives used to bond the synthetic fibers to your natural lashes:


Heat Bonding

 

This method involves heating up the ends of the synthetic fibers to create a chemical reaction between the fibers and the adhesive.

Once the adhesive bonds to both the synthetic fibers and your natural lashes, the synthetic fibers are pulled tightly against your natural lashes, creating an extended look.

Advantages of applying eyelash extensions using heat bonding include:

  • Stronger bond between synthetic fibers and your natural eyelashes
  • Can be worn with mascara
  • Doesn’t require removal before showering or swimming

Disadvantages of applying eyelash extension using heat bonding include:

  • Requires a professional technician to apply
  • May cause irritation
  • Is best suited for those who don’t like wearing makeup

If you decide to go with heat bonding, make sure that you choose a reputable company that offers quality service and products.

Glue Bonding

 

This method uses a glue-like substance to adhere the synthetic fibers to your lashes. Once the glue dries, the synthetic fibers are held firmly in place, creating an extended look that lasts for weeks.

Advantages of using glue bonding to apply eyelash extensions include:

  • Easy application process
  • No need to remove prior to showering or swimming
  • Will not affect the appearance of your natural lashes

Disadvantages of using glue bonding include:

  • It requires more skill than heat bonding
  • The synthetic fibers can sometimes start to fall out after a few days

Which Method Is Best For Me?

 

While there is no right or wrong way to apply eyelash extensions, many people prefer heat bonding because it creates a stronger bond between the synthetic fibers and your lashes.

However, if you want to wear mascara with your extensions, you may find that the glue-bonding method works better for you.


What Adhesive Is Used In Eyelash Extensions?

 

The glue that is used to attach eyelash extensions in glue-bonded treatments is an important part of the process. Eyelash adhesive is available in several different forms, including liquids, gels, and pastes.

Each type has its own advantages and disadvantages, so choosing the correct form will depend on what kind of treatment you’re looking for.

Liquid Eyelash Adhesive

 

Liquid eyelash adhesive is ideal for use with heat bonding. It’s easy to apply, and once applied, it doesn’t dry out your eyes.

However, liquid eyelash adhesive does contain alcohol, which means that it should never be used around children or pets.

Gel Eyelash Adhesive

 

Gel eyelash adhesive is often recommended for those who prefer to wear their extensions without mascara. Because gel eyelash adhesive is thicker than liquid eyelash adhesive, it creates a stronger bond when applied.

However, gel eyelash adhesive also contains alcohol, which makes it unsuitable for use around children or pets. If you have sensitive skin, you might consider using a water-based gel instead.

Paste Eyelash Adhesive

 

Paste eyelash adhesive is a thick paste that is usually mixed with water to create a consistency similar to toothpaste.

The advantage of this product is that it can be easily applied by hand, making it suitable for those who aren’t comfortable using a brush. However, paste eyelash adhesive can irritate your eyes or cause an allergic reaction, so it should only be used as a last resort.

What Ingredients Are In Eyelash Adhesive?

 

What Ingredients Are In Eyelash Adhesive

In order to better understand eyelash extensions, it can be useful to have a more comprehensive understanding of the ingredients that are typically used in eyelash adhesives.

Here are some common ingredients found in eyelash adhesive products:

Cyanoacrylate

 

This ingredient is the most common component in eyelash adhesive and is composed of cyanide and acrylate. Cyanoacrylates are known for being highly effective at creating strong bonds between lash fibers and synthetic fiber strands.

They also tend to be very sticky, which helps them adhere well to both synthetic fiber strands and your natural lashes.

Silicone

 

Silicone is another commonly used ingredient in eyelash adhesives. This substance is non-toxic, waterproof, and resistant to extreme temperatures.

Silicone is also able to withstand high levels of moisture, which makes it perfect for use around the eye area.

Polyvinyl Alcohol (PVA)

 

PVA is a polymer that is derived from vinyl acetate. PVA is widely used in cosmetics, including eyelash adhesive, due to its ability to provide excellent film-forming properties.

Additionally, it is highly flexible, which allows it to conform to the shape of the lash fibers.

Poly Methyl Methacrylate

 

PMMC is a plasticizer that is added to many cosmetic products, including eyelash adhesive and is important for ensuring that the extension fiber of eyelash extensions remains fixed and attached to your natural lashes.

PMMC is also considered safe for use around the eye, but it may cause irritation if it comes into contact with your eyes, so must be used carefully.

Hydroquinone

 

Hydroquinone is an antioxidant used in lash glue that is used to prevent the oxidation of the glue during storage.

Hydroquinone is also used in other beauty products, such as face masks and moisturizers, and helps to prevent the lash adhesive from drying out too quickly, giving it a chance to work as the lash artist applies the new lashes.

Hydroquinone is unique in that it remains in a liquid form while in the tube, but then turns to a solid as soon as it makes contact with the air.

Carbon Black

 

Carbon black is a pigment that is added to eyelash adhesive to help ensure that the adhesive does not discolor over time.

Carbon black is made from carbon and has been used since ancient times to make pigments. It is also used in mascara because it provides intense color without clumping or flaking.

Formaldehyde

 

Formaldehyde is a chemical compound that is used to preserve dead tissue. Formaldehyde is also used in nail polish removers, hair dyes, and disinfectants.

Because of its toxicity, formaldehyde is regulated under the Safe Cosmetics Act and is often released as a by-product of eyelash extensions as a result of the curing of the cyanoacrylate that is a part of the lash adhesive.

In small doses, exposure to formaldehyde is harmless, but prolonged exposure can lead to respiratory problems, skin rashes, and even cancer.

What Factors Can Impact Lash Adhesive?

 

There are a number of factors that can have an impact on the adhesive used in eyelash extensions, and these include:

Humidity

 

The humidity level inside your home will affect how long your eyelash extensions last. If you live in a humid environment, your eyelash extensions will likely need to be replaced more frequently than those living in drier climates.

The reason for this is that humidity causes the glue to become more elastic, and can result in the glue coming away from both the extensions and the natural lashes more quickly.

Temperature

 

Eyelash extensions tend to last longer when they are applied at cooler temperatures. This is because the glue becomes less sticky when it is cold, allowing the lash artist to apply them more easily.

However, applying for eyelash extensions at colder temperatures may require extra care and attention to avoid injury to your natural lashes.

Curing Time

 

Eyelash extensions should be cured for approximately five minutes before being removed.

Curing the lash glue allows it to harden and set properly, which prevents the glue from pulling off the extensions and causing damage to your natural lashes. If the glue is left uncured for too long, it can dry out and crack, making removal difficult.

Expired Adhesive

 

Lash glue used by your lash technician must be in date, and if it is expired, it could cause irritation and discomfort. Expired lash glue adhesives can also leave residue on your eyes, which can irritate your eyes and cause redness.

What Considerations Need To Be Taken Into Account When Applying Lashes?

 

The adhesive used in eyelash extensions is mostly safe when applied correctly, but it is important to know what precautions to take when applying lashes so that you do not end up with any unwanted side effects. Here are some things to consider when applying lashes:

Do Not Allow Contact Between The Eyes And The Adhesive

 

When applying lashes, it is best to keep the area around your eyes clean and free of debris. This includes using a makeup wipe to remove any excess eye makeup prior to application.

Also, try to avoid touching your eyes directly after removing your contacts. Doing so can allow bacteria to enter through your tear ducts and into your eyes.

Make sure that the lash adhesive does not come into contact with the eyes; this can cause irritation or infection.

Keep The Area Clean After Application

 

After applying lashes, wash your hands thoroughly with soap and water to remove any remaining adhesive from your skin. Make sure to scrub all surfaces where the adhesive was applied, including under your nails.

Use An Approved Adhesive

 

If you are unsure about the safety of the adhesive used in eyelashes, it is always recommended to use an approved adhesive.

These adhesives are tested extensively by third-party laboratories to ensure that they meet industry standards and regulations. They are designed specifically for use in eyelash extensions, so they are safe and effective.

These substances are required to go through rigorous testing, including toxicity tests, to ensure that they are safe for humans.

It is important to note that these adhesives are not intended for direct application to the eyes, but only to be used exactly as directed. One thing to note is some lash glues will create fumes and certain clients can be sensitive to the smell causing a headache.

Apply Only Enough Adhesive

 

It is important to only apply enough adhesive to secure the lashes securely onto your own lashes. Too much adhesive can make it harder to remove the extensions later on, as well as cause irritation or even a headache .

Once you have finished applying lashes, it is important to remove any excess adhesive that may remain on your face. You will need to gently rub your fingers over the adhesive until it has completely dried.

Then, carefully peel away the extensions one at a time.

Final Thoughts

 

False eyelashes and lash extensions are an excellent way to enhance your appearance. However, it is extremely important to use the correct products and techniques to achieve the perfect look.

Make sure that you follow all instructions provided by your lash tech for eyelash extension glue ingredients, so that you avoid any unwanted complications, and ensure that your adhesive and ingredients are of the highest possible quality.
