Why So Many Lash Artists Are Scared of LED/UV
- And Why It's the Future of the Industry Anyway
By Sarah Perovich - Lash Artist, Founder & Director of lummuse
Ask a room full of lash artists how they feel about LED/UV curing and you'll get two very different reactions. Some swear by it. Others won't go near it - and honestly, their hesitation usually makes sense.
The fear isn't irrational. It's earned.
Where the Fear Actually Comes From
Most artists who are wary of LED/UV aren't scared of the technology itself. They're scared of what they've seen, heard, or personally experienced with the devices currently flooding the market. Cheap imports with no independent testing behind them. Devices where the LED head was clearly sized without much thought for how close it sits to the eye. Output that seems fine for a few months, then quietly starts drifting - curing inconsistently, or not quite fully, without any obvious warning sign until a client has a reaction or a bond fails early.
That's not a fear of LED. That's a completely reasonable response to an unregulated corner of the industry where "peak wavelength" and "constant current" are terms most suppliers never mention, because most devices have never been tested against them.
So when an artist says "I'll stick with traditional glue, thanks" - they're not being behind the times. They're being cautious in a market that hasn't given them a good enough reason to trust otherwise.
The Bigger Shift LED/UV Actually Offers
Here's what gets lost in that caution, though: for as long as lash extensions have existed, retention has never just been about skill. Every artist learns to think in variables that have nothing to do with the actual lashing - oil levels, pH balance, humidity, how well a client follows aftercare, heat exposure in the days after application. You can do flawless isolation and placement and still lose a set early because of a factor that was never really in your control.
A properly built LED/UV device changes that equation entirely. A full cure in seconds, done correctly, means retention stops being a moving target shaped by everything that happens after the client leaves the chair. The bond is set. Done. Which means the only variable left worth obsessing over is the one that should've been the focus all along - the artistry itself.
Mapping, styling, symmetry, designing a set that suits the client in front of you, instead of troubleshooting why last week's set didn't hold.
That's not a small upgrade. That's the industry moving from unpredictable to controlled - and it's exactly why LED isn't a trend artists should wait out. It's the direction lashing is heading, whether the market's ready for it or not.
The Fear Is About the Device, Not the Destination
The real problem is that the industry has let "LED curing" and "poorly made LED curing" become the same conversation. They're not. The solution was never to avoid LED - it's to stop accepting devices that haven't earned an artist's trust.
Before adopting any LED device, the questions worth asking are the ones most suppliers hope you won't:
Has wavelength output been independently verified, or just claimed?
Does the device hold constant current, or drift as it heats up or the battery drains?
Was the LED head positioned with genuine consideration for eye safety?
And if something goes wrong, does the supplier stand behind their product - or blame the artist?
Why We Built CURED Differently
This is the gap I set out to close with CURED by lummuse. The device runs on a 405nm quartz-tipped LED with a gold-plated copper housing, mains-powered through a foot pedal with no battery - removing one of the most common failure points I've seen in other devices: output drifting mid-service as a battery discharges.
I spent three years working with a range of LED devices before building my own, then a full year testing my own prototype across my own salon, with my staff, and with a small number of other salons around Australia - zero adverse incidents recorded, while every other device I'd previously used developed problems within months.
CURED is also never sold as just a device. Every artist who buys one completes certification first - real training in why correct wavelength and constant current matter, so the fear that's kept so many artists on the sidelines gets replaced with actual understanding.
LED isn't something to be scared of. Being handed an untested device with no training and told to figure it out - that's the part worth fearing.
Fix that, and LED stops being a risk and becomes what it should have been from the start:
the standard the whole industry moves toward.
