What Are The Sky Glue Ingredients?

Nowadays it’s the norm to question what exactly we’re eating and drinking. We understand that what we put inside us affects the way that we look and feel and, for the most part, those are things that we really care about.
However, when it comes to beauty products, it seems that we’re willing to stretch the boundaries a little more. It appears that some people are going the extra mile to keep their youthful looks, even if that means ingesting or applying potentially harmful substances to their bodies.
Within the lash community there’s often debates around whether the eyelash extension adhesives used are safe or not. In this post, we’re going to take a look at what exactly the ingredients of Sky Glue are, what they do, and whether or not they are safe to use.

What Are The Sky Glue Ingredients?

Let’s list them out and then go into more detail about what each of them do below.

Sky Glue Ingredients

Ethyl Cyanoacrylate

Ethyl Cyanoacrylate is the main ingredient in all professional eyelash glues, in fact it’s the basis of almost all quick drying adhesives. So when someone says “this lash glue smells suspiciously like nail glue” – well, they’re spot on because it’s made from exactly the same base ingredient!

Without going deep into the science of what this particular chemical is made up of, we can simply say that it is a quick self-hardening solution. It’s what makes the adhesive grab onto lashes and dry almost instantly.

Poly (Methyl Methacrylate) – (PMMA)

Simply put, Poly (Methyl Methacrylate) is the part of the adhesive that forms the long lasting, strong bond – it’s what’s responsible for your super long retention.

So when you mix Ethyl Cyanoacrylate with Poly (Methyl Methacrylate), you have the two most important aspects of a lash glue covered: the quick drying, instant bond that grabs the lashes and then the long lasting strong holding bond that gives you several weeks of retention.


Hydroquinone is only present in lash adhesives in tiny amounts, and yet it serves an important purpose – that is to prevent the glue from polymerizing (curing) inside the bottle. It’s what keeps your glue from drying/hardening, before you’ve had a chance to use it.

Carbon Black

Carbon Black is what’s responsible for the deep black color of the adhesive. Obviously, this ingredient is only included in black adhesives and it’s not present in clear glues.

Are The Ingredients Safe?

There are official reports in both the UK and the US that confirm that the use of Ethyl Cyanoacrylate (the main ingredient) is safe and that additional studies are not necessary.

The US Cosmetics Database also states that Poly (Methyl Methacrylate) is safe to use, and it is rated a low hazard ingredient – no problems there then!

In large amounts, hydroquinone can be used to lighten blemishes such as scars on the skin. The FDA have not done any carcinogenic tests on humans so they have not formed an opinion on how dangerous it is to us, however some research suggests that applying significant amounts of it directly to the skin may cause problems. However, putting this aside, in lash adhesives it is present in such a tiny amount (less than 0.1%), and it’s not applied directly to the skin, so there’s absolutely nothing to worry about.

There is some evidence that Carbon Black powder can cause problems in the lungs if breathed in; however in lash adhesives it is dissolved in liquid and hence it’s not possible to inhale in its powder form.

So it’s pretty conclusive that the ingredients in Sky Glue are safe to use then!

What About Formaldehyde?

Formaldehyde is a word that’s banded around in lash forums all the time. It’s a toxic chemical that is dangerous to breathe so it’s not surprising that people worry about it.

It’s commonly thought that some glues are manufactured with formaldehyde. In actual fact no glues are made with formaldehyde – instead a really tiny amount of it is formed when the adhesive is cured on contact with the air. Similar to hydroquinone, the amounts we’re talking about are so small that it’s not something to worry about. Just remember to keep your work area well ventilated so any vapor is dispersed as quickly as possible.

All glues produce the same tiny amount of formaldehyde when curing. The reason lash companies advertise their products as ‘formaldehyde free’ is because everybody keeps asking about it!

What Does It Mean If My Adhesive Is Hypoallergenic?


Seriously, ‘hypoallergenic’ is just a made up term that marketers love to use to advertise their products. There is no official scientific or medical standard for a product to adhere to in order to be named ‘hypoallergenic’. The FDA only writes the following about it:

“Hypoallergenic cosmetics are products that manufacturers claim produce fewer allergic reactions than other cosmetic products. Consumers with hypersensitive skin, and even those with “normal” skin, may be led to believe that these products will be gentler to their skin than non-hypoallergenic cosmetics. There are no Federal standards or definitions that govern the use of the term “hypoallergenic.”

So don’t be fooled by the marketers out there!


The Sky Glue ingredients list has been thoroughly checked and is confirmed to be safe to use.

The majority of lash glues are manufactured using the same ingredients. What causes the differences in performance is the way the adhesives are formulated and the exact amount of each ingredient that is used (small differences can be significant).

Having said that, you should always check each adhesive you use for the list of ingredients to ensure that you are not putting yourself at risk. Developments in the lash industry are rapid, so the latest glue you try might have a different formulation and/or ingredients list and might not be as safe as you think.

Always check and be confident that you are not exposing yourself to dangerous chemicals!
