Understanding UV Radiation in Lash Extension Devices: Safety First, Always

Hey lash lovers! 💖

It’s Kati here – lash tech, educator, and someone who’s a little bit obsessed with all things LED and lash safety. 

But here’s the thing: with great technology comes great responsibility. Recently, the Radiation and Nuclear Safety Authority of Finland (STUK) published a report on UV exposure in lash devices – and trust me, every lash artist should know what it says.

Let’s break it down...

💥 Not All UV-LED Devices Are Created Equal

STUK tested six different lash devices sold online – from super cheap Amazon finds to professional salon tools. The results? 

• UV radiation levels varied up to 20x between devices.
• Three devices were rated Risk Group 3 (RG3) – the highest hazard classification.
• Prolonged UV exposure can lead to corneal inflammation or even cataracts.

Now, I don’t know about you, but my eyes are everything. I NEED them for what I do. So this kind of info made me pause and think: Are we taking UV safety seriously enough in our lash rooms?

🛡️ Protect Yourself, Like a Pro

Clients usually have their eyes closed, and eyelids actually block around 95% of UV rays. BUT – us lash techs? We’re exposed every single day, for a short period but still.

So here’s my go-to UV safety checklist:

✅ Always wear UV-blocking glasses. No exceptions, even for quick fills.
✅ Follow the device manual. Curing time and working distance aren’t suggestions – they’re safety guidelines.

Remember to take care of YOU.

🌞 What About Skin Damage & Cancer Risks?

I get this question all the time – “Isn’t UV bad for your skin?”

👉 Good news: LED lash devices don’t emit UVB, which is the kind linked to skin cancer.
👉 They emit mainly UVA and visible blue light, which is not harmful in short doses.
👉 Exposure time is super short, so the actual skin risk is very low.

🧠 Choosing a Safe UV-LED Lash Device (A Lash Tech’s Checklist)

When buying your next lash lamp, don’t just go for what’s cute or cheap. Here’s what really matters:

✨ Ask for certifications like EN 62471:2008 and ISO 21348. (Psst... the myLashy LED KIT meets both, tested in the EU!)
✨ Avoid devices with no safety info, no manual, or no CE mark. Red flag!
✨ Look for proper labeling and clear instructions – you shouldn’t have to “figure it out.”

Let’s be real – a €40 lamp might look the same on the outside, but inside? Total gamble.

📚 FAQ – Quick Lash Safety Q&A

Can UV/LED lash devices damage your eyes?
👉 Yes – especially high-risk ones without protection. That’s why proper eyewear is a MUST.

What if I don’t know if my device is certified?
👉 Ask the seller. If they can’t provide test reports or standards, it’s probably not worth the risk. Plus be shure from which country you buy that you can be sure it is safe & has warranty
