Since its launch, Fusion has been our number 1 best-selling lash extension glue. The first in our adhesive series, Fusion is the go-to adhesive for many lash technicians due to its quick drying time and ability to work within a range of environments.

Why Fusion Lash Extension Glue?

  • Works outside its optimal temperature and humidity ranges.
  • Great retention.
  • Thin consistency / viscosity.
  • Instantly ‘grabs’ the lashes.
  • Quick setting time.
  • Well-suited to most lash technicians.

How to Use Fusion Lash Extension Glue:

  1. Ensure you shake the adhesive thoroughly using a vortex glue shaker. Place bottle on top of the mixer and press down for around 3-5 seconds. Alternatively, shake for 1-2 minutes if doing so by hand.
  2. Place a drop of Fusion onto adhesive magic paper, a  jade stone or a plastic adhesive holder.
  3. Apply the lashes as normal.
  4. When the adhesive begins to thicken in consistency, dispense a new drop. The time between fresh drops will depend on the temperature and humidity of your lash room.
  5. Once finished, add a drop of water to your dispensed adhesive to shock cure it and prevent the release of further fumes. Speed up adhesive curing time by using a lash nano mister over the completed set.

If you’re looking to increase longevity and prevent your fans from closing, our 3-step eyelash extension prep ‘quick’ series has been designed to work alongside Fusion for longer lasting lashes.

If you find Fusion too quick, you might find that our slower Magnet glue for lash extensions will be better suited to you.

Fusion Storage Instructions:

Once opened we recommend storing Fusion in one of our airtight opaque vac seal containers.

Keep the bottle upright and store in a cool, dark room. Shelf life unopened is 9 months. Use within 2 months of opening.

Please note: Fusion should not be disposed of with general household waste. Please check with your local authority for recommended disposal.

Fusion Additional Information:

Fusion is made in the UK and all ingredients are EU approved and are independently safety assessed to approve ingredients and the application.

Note: sample tubes unscrew at the bottom. There is no need to cut the end off.

Patch test 48 hours before:
We recommend to patch test at least 48 hours before treatment and to do so by applying extensions to the lashes. We do recommend placing at least 8-15 extensions on each eye as this will more likely show up an allergy than by just putting on 2 or 3.

    Jenna Godfrey

    This glue is by far the BEST! Like most lash techs, I have tried so many different ones ranging from £12-£58!
    But fusion wins everytime. It’s thin viscosity and super quick drying time and literally the fact you can use it and love it no matter what humidity, make it the winner for me.
    Plus Angelina is always so kind and helpful with any questions!
    Thanks lash factor for bringing us quality lash products without the huge price tag 🙌🏻

    Amazing retention, my clients come in after 4 weeks with most of their lashes in tact. Doesn’t give off a strong smell or fumes, and dries as quickly as described. I would only buy lash factor glues!

    The very best adhesive in the market. I have tried several other brands, this adhesive is my favourite as it dries within 2 seconds and offers an excellent retention for both volume and classic.
    I use it with humidity around 50-55% and it never lets me down.
    First I shake it for 2 min, then allow it to settle for a minute, then I only disperse a small amount on top of 2 layers of 3M micropore tape on my glue ring and start working. It stays fresh for 30 min or so, no need to disperse big blobs or change it too often.
    Brilliant adhesive, no fumes or irritation to the eyes. Highly recommended and comes with Angelina’s amazing customer service.
