What is Superbonder Lash Sealant, Anyway? Your Most Common Questions, Answered.

Superbonder joined the London Lash collection back in 2019 and quickly became a staple of Lash Artist's lash extension kits all over the world, but what is it? Put simply, Superbonder is a lash glue sealant that’s used to cure your eyelash glue at the end of an lash extensions treatment. 

When Should You Use Superbonder Lash Sealant? 

You can use Superbonder at the end of every eyelash extensions treatment, whether it’s a full set or an infill. When you’re done with your set and you’ve gone through and checked for stickies, you can apply your Superbonder.

How Do You Use Superbonder Lash Sealant?

Superbonder is applied in much the same way as the majority of your pretreatment - take a microfibre brush or a cleansing applicator and apply a little drop of Superbonder to the lash brush. Dab off the excess onto a tissue to ensure it does not run into your client’s eyes and then pat the Superbonder along the lash glue bonds on the eyelash extensions. Give the lashes one final brush and then reveal the set to your client!

What Does Superbonder Lash Sealant Do?

Superbonder cures your eyelash glue, but it does it in a different way to water, which means that the lash glue bond remains flexible and doesn’t become brittle like it does if you cure it with water (this is why we recommend using Superbonder over a nanomister). Added flexibility means that your eyelash glue bonds - and by extension your lashes - can move as the natural lashes move without snapping or crumbling, which increases your lash retention times. 

By curing the lash glue instantly you also lock in the lash glue fumes, which increases your clients’ comfort upon opening their eyes at the end of the treatment, and also helps to reduce the risk of allergic reactions to eyelash extensions glue as they are not being exposed to the lash glue fumes for as long as if you had not used Superbonder. We must mention here though, that if a client is known to be allergic to the eyelash extensions glue this is not a remedy and they should still avoid having eyelash extensions treatments to protect their health.

Does Superbonder Cause Shock Polymerisation of Lash Glue?

Any liquid applied to fresh lash glue will cause shock polymerisation. Shock polymerisation is a result of the cyanoacrylate molecules in the eyelash glue curing too quickly, and instead of staying clear or black in colour, it takes on a white appearance. Shock polymerised lash glue is also really brittle, which isn't great for lash extension retention to say the least. 

Superbonder, when applied as directed, doesn't cause shock polymerisation in your lash extensions glue, it just cures it nice and quickly whilst maintaining flexibility, the colour (or lack of) that your lash glue is supposed to be. This is due to the stabilising ingredients present in Superbonder which don't exist in water alone.

What’s the Shelf Life of Superbonder Lash Sealant?

Before you open your Superbonder, you have a shelf life of at least 2 years to open and use it - just check the date on the bottom of the bottle for the DOP (date of production) to make sure you know when those 2 years will be up. 

After opening your bottle of Superbonder, you have 6 months to use it before it becomes less effective. It won’t become harmful at all once that 6 months is up, it just isn’t quite as effective as it will be when used within that 6 months - to ensure you get the best results, we recommend that you take a piece of lash tape and just write the date that you opened the Superbonder on it so that you can keep track of how long it’s been open. 

How Much Does Superbonder Lash Sealant Cost? 

A bottle of Superbonder is £27.99. Based on the assumption that you’ll be using around 0.15ml per lash treatment, you can get around 50 treatments out of a bottle of Superbonder, costing you £0.56 per treatment. 

We don’t know about you, but 56p per treatment for client comfort and longer lash retention times sounds like a pretty good deal to us!

Can You Put Superbonder Lash Sealant in a Nanomister?

No. Definitely not. While a little bit of Superbonder accidentally coming into contact with the skin during application isn’t the end of the world, it is recommended that you avoid the skin. A light dusting of Superbonder A. won’t be able to do its job on the eyelash glue bonds properly and B. may cause irritation to your clients’ skin. Superbonder was developed specifically to be used on the lash glue bonds at the end of the lash treatment, so if you use it in a way that it has not been developed for, you will be the one liable if your client has some adverse effects and seeks legal action. Putting it in a nanomister is not a clever hack, so please don’t do it! 

Can You Use Superbonder Lash Sealant on All of Your Clients?

Yes you can, it’s mostly advisable for those clients who like to swim a lot or who shower soon after treatment and struggle with their retention as a result (we’d also highly recommend pulling out the Booster for any client who's eyes are prone to watering). 

Superbonder can absolutely be used for any of your clients though, there is no-one it won’t work well for so you may as well round the treatment off with it! As we’ve mentioned, you’re reducing the risk of discomfort and of allergic reactions while increasing lash retention times, so there’s really no downside!
