What are LED Lash Extensions & How Safe are they?

The Safety of AURA Monaco LED Lash Extensions

A modern breakthrough in lash technology

The beauty industry is constantly evolving, and one of the most exciting innovations is LED lash extension systems like those developed by AURA Monaco. These systems use a specialized LED (often referred to as “purple light”) to instantly cure lash adhesive—offering improved retention, reduced irritation, and enhanced client comfort.

In this blog, we’ll break down how LED lashes work, the step-by-step application process, and most importantly—the safety of the glue, equipment, and curing light.

What Are LED Lash Extensions?

LED lash extensions use a light-activated adhesive that cures instantly when exposed to a targeted LED wavelength. Unlike traditional lash glue that air-dries over time, LED glue hardens in 1–2 seconds, creating an immediate bond.

This innovation eliminates many of the common challenges lash artists face with humidity, drying time, and client sensitivity.

Step-by-Step Application Process

The application of LED lashes is very similar to classic lash extensions—with one key difference: light curing replaces air curing.

1. Preparation

• Cleanse lashes thoroughly

• Isolate natural lashes

• Ensure the eye is fully closed and protected

2. Adhesive Application

• Dip the extension into LED lash glue

• Apply to the natural lash as usual

3. LED Curing (Purple Light)

• Position the LED lamp approximately 10–15 cm above the lash line

• Activate the light using a foot pedal

• Cure for 1–2 seconds

4. Immediate Set

• The bond is instantly cured

• Move directly to the next lash without stickies

  
  

The Safety of LED Lash Glue

Key Ingredients

LED lash adhesives typically contain:

• Ethyl cyanoacrylate (bonding agent)

• Photoinitiator (reacts with light to cure)

• Stabilizers

Why LED Glue Is Considered Safer

1. Reduced fumesTraditional lash glue can release fumes for up to 24–48 hours while curing. LED glue cures instantly, meaning fumes are eliminated almost immediately.

2. Lower allergy riskMany reactions come from:

• Carbon black (pigment)

• Prolonged exposure to cyanoacrylate fumes

LED adhesives are often clear (no carbon black) and cure instantly, reducing exposure.

3. Controlled curing processBecause curing is activated only under light, technicians have full control—no premature drying or inconsistent bonding.

The Safety of the LED (Purple) Curing Light

One of the biggest concerns clients have is: Is the light safe for the eyes?

The Reality

• Professional LED lash systems use low-wattage, targeted light designed specifically for adhesive curing—not skin penetration

• The light is directed onto the lash line, not into the eye

• Clients keep their eyes fully closed during treatment

Built-In Safety Measures

• Lamp positioned above the eyelid—not directly into the eye

• Protective eyewear (UV400 glasses) for technicians

• Short exposure time (1–2 seconds per lash)

When used correctly, LED lash systems are considered safe and tested for professional use.

Who Should Avoid LED Lash Systems?

While safe for most clients, LED lash systems may not be suitable for individuals with:

• Photosensitivity disorders

• Epilepsy

• Recent eye-area procedures

• Use of photosensitizing medications

A proper consultation is essential before treatment.

Benefits of LED Glue vs. Traditional Lash Glue

1. Instant Curing

• No waiting time

• No “stickies”

• Faster appointments

2. Minimal Fumes

• More comfortable for sensitive clients

• Reduced irritation during and after application

3. Better Retention

• Strong, immediate bond

• Less environmental dependency (humidity/temperature)

4. No Aftercare Restrictions

• Clients can get lashes wet immediately

• No 24–48 hour waiting period

5. Improved Allergy Tolerance

• Many previously sensitive clients can wear lashes again

  
  

Professional Safety Considerations

Even though LED systems are advanced, they are strictly for trained professionals:

• Proper isolation is still critical

• Ventilation is recommended due to cyanoacrylate

• Glue must never contact skin or eyes

• Equipment must be used according to manufacturer guidelines

To conclude, LED lash technology—especially systems like those from AURA Monaco—is transforming the lash industry by making extensions faster, cleaner, and safer for many clients.

With:

• Instant curing

• Reduced fumes

• Controlled application

• Low-energy LED exposure

this method offers a significant upgrade over traditional lash adhesives.

However, like all professional beauty treatments, safety depends on proper training, correct usage, and client suitability.

Did You Know?

Traditional lash glue can continue curing and releasing vapours, for up to 48 hours, while LED systems complete the process in seconds, dramatically reducing exposure to irritants.
