LED Lash Extensions
About LED Lash Extensions
A new patented technology, LED lash extensions is a gel curing technique that bonds and cures false lashes to the natural ones using a safe, low-level LED light (much like the light delivered during professional facials or from at-home LED face masks). Similar to the way LED light is used to cure gel nail polish.The light used is visible light, so there is almost no effect on the human body.
Benefits of LED Lash Extensions
LED lash extensions offer several unique benefits compared to traditional lash extension methods. Here are the key advantages:
1. Stronger Bond & Longer Retention
The LED light cures the adhesive instantly and more thoroughly, resulting in a stronger bond that can last up to 50% longer than standard lash extensions.
2. Water & Oil Resistance
The cured adhesive becomes more resistant to water, oils, and humidity, making the lashes more durable in everyday conditions.
3. Reduced Fume Exposure
Since the adhesive is cured instantly, there's less time for fumes to be released, which can mean less irritation for both the client and the lash artist.
​
4. Faster Setting Time
No need to wait for the glue to dry. The curing process is immediate with LED, allowing for a quicker application and reducing the chance of lashes sticking together (stickies).
​
5. Hypoallergenic Formulas Available
Many LED adhesives are formulated to be gentler on sensitive eyes, making the service accessible to more clients.
​
6. Less Risk of Shock Curing
LED curing is controlled and consistent, reducing the risk of shock curing (which happens with sudden humidity changes in traditional glue).
​
7. Improved Styling Precision
Instant curing allows lash artists to have more control over lash placement without worrying about the extensions shifting before drying.
Difference Between Regular LED Lashes and Allergy Free LED Lashes
LED lash extensions come in two varieties: regular and allergy-free.
The difference between regular LED lashes and allergy-free LED lashes mainly comes down to the materials used and the adhesive formulation:
1. Materials:
Regular LED Lashes: May contain materials that can trigger allergic reactions in sensitive individuals (e.g. latex, certain plastics, or glues with formaldehyde).
Allergy-Free LED Lashes: Are made with hypoallergenic materials, often free from common irritants like latex, parabens, or formaldehyde. The lash fibers and base are typically gentler on the skin and eyes.
2. Adhesive/Glue:
Regular LED Lash Adhesive: Often contains stronger chemicals to ensure long-lasting wear, which can irritate those with sensitive eyes or skin.
Allergy-Free LED Lash Adhesive: Specially formulated to be gentle, with low fumes and minimal irritants. It may be medical-grade and designed for sensitive clients.
3. Intended Users:
Regular LED Lashes: Suitable for people with no known allergies or sensitivities.
Allergy-Free LED Lashes: Designed for clients with sensitive eyes, skin conditions, or a history of allergic reactions to lash products.
4. Price and Availability:
Allergy-free options are often slightly more expensive due to the specialized ingredients and testing, and may be available only through professional suppliers or salons.
*When choosing between regular LED lash extensions and allergy-free LED lash extensions, consider your skin sensitivity and any previous reactions to lash glue. If you have a history of allergies, the allergy-free option may the safer choice, providing comfort without compromising on style. On the other hand, if you have no allergy issues, regular LED lash extensions can offer a wide variety of looks. Ultimately, your comfort and preferences should guide your decision.

Lash Allergy Guideline – K Brows & Lines
1. What is a Lash Allergy?
A lash allergy is a sensitivity or allergic reaction to one or more components in lash extension products, most commonly the adhesive (cyanoacrylate-based).
​​
2. Common Symptoms:
Redness or swelling of eyelids
Itching or burning sensation
Watery eyes
Puffy or irritated skin around the eyes
Symptoms usually appear within 24–48 hours after application
​​
3. Allergy vs. Irritation:
Allergy is immune-related and usually persists or worsens.
Irritation is often due to fumes or improper application and usually subsides quickly.
​4. Prevention Steps:
Patch Test: Always do a patch test at least 24–48 hours before the full set application.
Ventilation: Ensure proper air circulation during application.
Low-Fume Adhesive: Use sensitive or low-fume adhesives for prone clients.
Isolation & Cleanliness: Proper lash isolation and clean tools reduce risks.
​5. If a Reaction Occurs:
Remove the lashes professionally ASAP.
Advise the client to avoid rubbing their eyes.
Recommend seeking medical attention if symptoms persist.
Do not reapply extensions until cleared by a healthcare provider.
​​
6. Long-Term Considerations:
Once allergic, clients may remain allergic to lash adhesives permanently.
Consider alternative beauty treatments like lash lifts or tints for sensitive clients.
LED Lash Extensions - Q & A
Q: How are they different from regular lash extensions?
A: Instead of air-drying, the LED glue cures instantly under a safe LED light, making the lashes more resistant to oils, water, and heat. They also reduce the risk of allergic reactions from traditional adhesives.
Q: Are LED lash extensions safe?
A: Yes, when applied by a certified professional using high-quality products, LED lash extensions are completely safe. The LED light is specifically designed for cosmetic use and doesn’t harm your eyes or skin.
Q: Do LED lash extensions last longer?
A: Yes! Clients typically enjoy longer retention—up to 6–8 weeks depending on their lash cycle and aftercare.
Q: Is the LED light harmful?
A: No, the LED used is a low-level visible light. It’s safe, painless, and only targets the lash adhesive for quick curing.
Q: Can I still wear makeup and use oil-based products?
A: Yes, LED-cured lashes are more resistant to oils, so you have more freedom with your skincare and makeup routine.
Q: Who is a good candidate for LED lash extensions?
A: Anyone who wants longer-lasting lashes, has experienced sensitivity to regular lash glue, or wants to reduce the chances of lash fallout.
