Photobiological Safety Testing
IEC 62471 is an international standard used to evaluate potential optical radiation hazards from lamps and LED systems. Testing evaluates light exposure in relation to established eye and skin exposure limits.
Understand the Technology. Use It With Confidence.

The Evidence
What Has Been Tested?
The Lash Plus LED module has undergone testing covering photobiological safety, electrical safety, electromagnetic compatibility and wireless operation.
Exempt Risk Group — RG0
At the standard 200 mm testing distance, the tested LED module was classified as Exempt Group, also known as Risk Group 0, under IEC 62471 test conditions.
Risk-group classification describes the specific laboratory test conditions. It does not replace correct professional use, training or the instructions provided in the user manual.
Professional Protocol
Safe Practice During Every Appointment
Equipment testing and correct technique work together. Follow these principles whenever using the Lash Plus LED system.
Consult First
Ask about allergies, eye conditions, light sensitivity, medications and recent treatments.
Protect the Eye Area
Ensure the client’s eyes remain fully closed and apply suitable under-eye pads or shields.
Avoid Direct Viewing
Never stare directly into the LED or deliberately direct the light into an open eye.
Use Compatible Adhesive
Only use an LED-compatible lash adhesive and follow its application and curing instructions.
Cure Only When Ready
Position the extension first, then apply a short, controlled activation to the adhesive bond.
Stop if Discomfort Occurs
Stop the service if the client reports pain, unusual warmth, stinging, irritation or visual discomfort.
When Additional Caution Is Required
Do not proceed without appropriate professional advice when a client reports photosensitivity, a light-sensitive medical condition, photosensitizing medication, an active eye or skin condition, recent eye surgery, or unexplained sensitivity around the treatment area.

Common Questions
LED Safety, Explained Simply
Is the Lash Plus light UV or LED?
LED describes the type of light source. The Lash Plus system emits light at approximately 400 nm, around the boundary between violet visible light and near-UVA. It is not a UVC germicidal lamp.
What does Risk Group 0 mean?
Risk Group 0, also called the Exempt Group, means the measured output remained within the IEC 62471 exempt-group limits under the specified laboratory test conditions. The Lash Plus result was measured at the standard 200 mm test distance.
Should the client’s eyes remain closed?
Yes. Clients should keep their eyes fully closed throughout the procedure, with suitable under-eye pads or shields correctly positioned. The LED should never be deliberately directed into an open eye.
Does LED curing prevent adhesive allergies?
No lash system can guarantee that an allergic reaction will not occur. LED curing controls when the compatible adhesive is cured, but normal consultation, ingredient awareness, professional technique and local patch-testing requirements still apply.
Can any lash adhesive be used?
No. Use an adhesive specifically formulated for compatible LED curing and follow the adhesive manufacturer’s curing, storage and application instructions.
What if a client is sensitive to light?
Do not proceed until the concern has been properly assessed. Ask the client to obtain advice from an appropriate healthcare professional, particularly when photosensitivity, medication, recent eye treatment or an existing eye or skin condition is involved.
