Eyelash Extension Glue: Black vs Clear

Ever wonder why some lash artists prefer black glue while others use clear?

Let’s break it down.

Black Adhesive

• Purpose: Black glue is one of the most popular choices among lash artists.

• Benefit: It adds intensity to the lash line and helps hide the bond between the natural lash and extension, meaning you don’t need to apply eyeliner.

• Ideal For: Clients who want a bold, dark lash line.

 

Clear Adhesive

• Purpose: Clear glue isn’t as commonly used but has its own benefits.

• Benefit: It creates a seamless bond that’s perfect for colorful lash sets, allowing the color to pop without the bond being visible.

• Ideal For: Beginner lash artists who are still perfecting their technique, or clients with allergies to black adhesives.

 

Which One Should You Use?

• Black Glue: Perfect for clients who want definition and depth.

• Clear Glue: Great for subtle looks, colorful lashes, or clients with sensitivities to black glue.

Both have their place in the lash world, and choosing the right one depends on your client’s preferences and needs.

What’s in Lash Adhesive?

Primary Ingredient: Most lash adhesives contain Ethyl-2-Cyanoacrylate, the same chemical used in superglue.

Why It Works: Ethyl-2-Cyanoacrylate has quick bonding properties, which are ideal for attaching eyelash extensions to natural lashes.

Manufacturing Process: Adhesives are made by mixing Ethyl-2-Cyanoacrylate with formaldehyde gas in a controlled environment. The chemical reaction forms the adhesive polymer, and any formaldehyde traces are removed during production.

Is There Formaldehyde in Lash Adhesive?

Fact: While formaldehyde is used in the manufacturing process, there is no formaldehyde in the final product.

Safety: After the chemical reaction and heating process, any formaldehyde present is removed, ensuring that there is no risk to clients during application.

What About Other Chemicals in Adhesives?

Additives: Some adhesives include chemicals like carbon black (for color) or hydroquinone (to extend shelf life).

Safety: These additives are safe in small quantities. Always review the Material Safety Data Sheet (MSDS) to ensure you're using a product with safe and minimal additives.

The Importance of Proper Adhesive Application

Effective adhesive application is essential for retention and client safety.

Keep these points in mind:

Surface Area: Apply enough adhesive to both the extension and the natural lash to create a solid bond. Insufficient adhesive results in a weak bond.

Avoid Overuse: Using too much adhesive leads to clumps. Apply just enough to ensure a secure bond.

Curing Process: Cyanoacrylate adhesives cure when exposed to moisture. This process generates heat, which can cause irritation or a stinging sensation. It’s normal and part of the bonding process.

Ventilation: Proper ventilation in the lash room is necessary to reduce irritation from adhesive fumes. Ensure the client’s eyes are fully closed to avoid exposing them to the fumes.

Does pH Affect Adhesive?

pH Impact: The pH of the natural lash and surrounding skin plays a role in how well the adhesive bonds. Lash adhesives work best in a neutral pH environment.

Solution: Some lash artists use primers to adjust the pH of natural lashes for optimal bonding. Ensure the primer is not overused as it may affect retention if applied incorrectly.

Caution: Avoid using highly acidic or alkaline products on the natural lashes, as they can weaken the bond.

Why You Don’t Need to Worry About “Off-Gassing”

Off-Gassing Explained: Off-gassing refers to fumes released during the curing process when the adhesive reacts with moisture in the air. However, these fumes are not harmful when used in a well-ventilated environment.

Myth: Some believe that adhesives continue to release formaldehyde vapors after curing, but this is inaccurate. The fumes released are not dangerous when proper procedures are followed.

Is Medical Grade Adhesive Necessary?

Medical-Grade Adhesives: Most lash adhesives are medical grade, designed for use around the eyes and skin, making them safe for eyelash extensions.

Ingredient List: Medical-grade adhesives typically list Ethyl-2-Cyanoacrylate as the main ingredient, with minimal additives. Check the MSDS to verify that the adhesive meets safety standards.

Can Super Bonder Help With Retention?

Super Bonders: Super bonders are used after lash extension application to help seal the adhesive and protect it from factors like humidity and oil. While they don’t directly improve the bond, they can enhance retention.

Key Point: Super bonders won’t fix poor application. Proper adhesive application is still the most important factor for retention.

Best Practices for Lash Adhesive Use

Follow these steps to ensure effective and safe lash adhesive application:

Clean the Lashes: Always clean the natural lashes to remove oil, dirt, and dead skin. Clean lashes improve adhesive bonding.

Use the Right Amount: Apply enough adhesive to create a solid bond without clumping.

Create a Neutral pH Environment: Use a primer to adjust the pH of natural lashes for optimal bonding.

Ventilation: Ensure your work area is well-ventilated to minimize exposure to fumes from the adhesive.

Use Medical Grade Adhesives: Stick to adhesives with simple, known ingredients and confirm their safety by reviewing the MSDS.

Shake Your Lash Glue

Why Shake?: Proper shaking ensures the glue ingredients are well mixed for the best results.

How to Shake: Shake side to side for at least 1-2 minutes. This will mix the adhesive properly.

What to Avoid: Don’t shake up and down as it can cause glue buildup around the nozzle, leading to clogs or a stuck cap.

Glue Shaker: If you use a glue shaker, start shaking it one minute before your appointment. You can also shake it during the day.

Always Burp Your Eyelash Glue

Why Burp?: Burping helps release air from the glue bottle, keeping it fresh and effective.

How to Do It: Gently squeeze the bottle to remove trapped air. This prevents your glue from becoming less effective over time.

Eyelash Glue Storage

Proper Storage: Keep your lash glue in an airtight container in a cool, dark place to preserve its freshness.

Pro Tip: Use silica gel beads or rice inside the container to absorb excess moisture.

Avoid Heat: Don’t place glue near a window or in a hot area. Keep it upright to prevent spills.

Humidity Control: Lash glue works best in a controlled environment. If you struggle with humidity:

• Use a warm mist humidifier for better results than a cool-mist one.
• If there’s too much moisture, use a dehumidifier.
• Consider a room divider to better manage humidity in larger spaces.

Cleaning Nozzles with Lint-Free Wipes

Why Clean?: A clean nozzle ensures the glue doesn’t clog, which can affect application and retention.

How to Clean: Use lint-free wipes to remove glue buildup. This prevents the nozzle from becoming stuck in the cap.

Pro Tip: Gently scrape or push off residue with a small scissor. Use a makeup sponge (lint-free) or foil to absorb glue residue.

Replace the Old Nozzle with a New One

• When to Replace: If the nozzle is too clogged or distorted, replace it to maintain glue quality and prevent difficulties when opening the bottle.

• How to Do It: Simply swap the nozzle with a new one to avoid issues like a stuck cap or poor glue flow.

Tips For Storing Your Lash Adhesive The Right Way

Storing your lash adhesive properly is key to ensuring its effectiveness and longevity. Adhesive is what holds your lashes in place for weeks, so it's important to store it right to avoid wasted product and poor retention. Here are some tips.

For Unopened Lash Adhesive

Use Silica/Oxygen Absorbers: Place these in an airtight container with the glue to prevent moisture.

Avoid Direct Sunlight: Never store glue in direct sunlight (no windowsills!).

Limit Fridge Storage: While it can be kept in the fridge, don’t leave it there for too long. Excessive moisture from condensation can cause problems. Max storage time in the fridge is 3 months.

 

For Opened Lash Adhesive

Store in a Cool, Dark Place: Keep it away from heat and sunlight to prevent it from becoming too liquid.

Use Silica/Oxygen Absorbers: These help keep moisture out and extend the shelf life.

Clean the Lid: Wipe any leftover glue off the lid to prevent clumps and blockages in the nozzle.

Use Within 3 Months: Once opened, it’s best to use the adhesive within 3 months. Store it properly to extend its shelf life, but after 30 days, its effectiveness will reduce.

Replace Every 30 Days: We recommend replacing your adhesive every 30 days after opening for best results.

 

Important Tip

No More Fridge Storage: If you’ve been keeping your opened adhesive in the fridge, it’s time to stop. The temperature fluctuations cause condensation, which breaks down the adhesive and reduces retention. Move it to a cool, dark place instead!

 

WHY SHOULD YOU CRYSTALIZE GLUE DROP AFTER YOU ARE DONE WORKING WITH IT?

• Decrease the fumes for both you and your client
• Fewer fumes, fewer sensitivities
• Use bonder to crystalize
• Your new drop will be more effective if there's not an old drop of glue nearby, causing fumes

Common Myths About Eyelash Adhesive

Here are some common misconceptions about lash adhesives and the truth behind them:

Glue Rings and Adhesive Reaction: Glue rings made from PBT plastic are safe to use and do not affect the quality of the adhesive bond. The plastic is chemically resistant, so it won’t react with the cyanoacrylate in the adhesive.

Formaldehyde in Adhesive: The trace formaldehyde used in the adhesive production process is removed before it is packaged for use. There is no formaldehyde present in the final product.

Cancer or Birth Defects: The levels of chemicals like PMMA in adhesives are very low. There is no evidence linking lash adhesives to cancer or birth defects when used properly in a salon environment.

Bacterial Growth: Bacterial contamination in adhesives is rare. As long as the adhesive is stored properly (sealed and kept cool), the risk is minimal.
