When it comes to creating long-lasting, irresistible lash extension results, success depends on more than just high-quality lashes, adhesives, or flawless technique. It also requires the smart use of supporting products—especially during preparation and immediately after application. That’s where the liquid routine becomes a critical step. From cleansing to bonding, these products play a powerful role in maximizing retention, ensuring safety, and enhancing client satisfaction. In this guide, we’ll walk you through the essential liquid routine every lash artist should master for smoother, cleaner, and longer-lasting lash sets.

The Power of Lash Liquid Essentials: From Prep to Post-Care, Every Drop Counts

Have you ever pondered the significance of liquids in eyelash extensions? If the process already seems simple—lash, glue, done—why complicate it with a shelf full of extra products?

Here’s the truth: Lash technicians are called lash artists for a reason. Eyelash extensions are a craft—and behind every flawless set is not just a skilled hand but a deep understanding of lash health, client needs, and the essential role of liquid products. From cleansing away oils and debris to creating the ideal bonding surface, these liquids set the tone for long-lasting retention and a safe, comfortable experience. A thoroughly prepped lash base leads to better adhesion—and ultimately, extensions that last longer on the natural lash.

But here’s the catch: it’s not just about using liquids—it’s about using the right ones, at the right time, and in the right order. Overusing or skipping a step can cause irritation, poor bonding, or lashes that simply won’t stay put. That’s why understanding the full liquid routine is essential for every lash artist aiming for consistently flawless results.

Step-by-Step Liquid Routine for Lash Artists

Perfect lashes start with the perfect routine. Know every step, and you’ll nail every set. When it comes to using eyelash extension liquids effectively, the process can be broken down into seven essential products, grouped across three key stages: Pre-Adhesive Prep, Adhesive Application, and Post-Adhesive Care.

Each stage plays a crucial role in lash retention, safety, and overall application success. Let’s walk through each one step by step.

Pre-Adhesive Prep

Step 1: Lash Foam Cleanser

The first and most important step in any eyelash care routine is cleansing. Lash foam cleansers are specially formulated to remove dirt, excess oil, makeup residue, and impurities from the natural lashes and eyelids—without disturbing the skin’s protective barrier. A properly cleansed lash line creates a strong foundation for better adhesive bonding, prevents premature lash loss, and ensures optimal hygiene throughout the lash-wearing period.

At Lii Lash, we offer three types of lash foam cleansers, each crafted with unique ingredients to suit different client needs:

• Soothing Lash Cleanser—infused with green tea extract for a calming effect.

• Gentle Lash Cleanser—Formulated with rosehip extract to nourish and soothe.

• Pure Lash Cleanser—unscented and minimalist, ideal for sensitive skin types.

All three formulas are oil-free, non-irritating, and suitable for all skin types. They provide deep yet gentle cleansing, effectively removing oil and debris without discomfort—while also hydrating and nourishing the natural lashes for a healthy lash base.

How to Use Lash Foam Cleanser:

1. Shake well before use

2. Pump 1–2 pumps of foam onto a cleansing brush 

3. Gently work the foam through the lashes and lash line in circular motions.

4. Rinse thoroughly with saline or distilled water

5. Pat dry with a clean towel or use an air blower

Pro Tip: 

Use a mini handheld fan or lash air blower after cleansing to speed up drying and prep the lashes for the next step.

Step 2: Protein Remover 

After cleansing, the next essential step in the lash pre-treatment process is using a protein remover. Much like a deep facial cleanser, this product goes beyond what a foam lash cleanser can achieve—not just removing surface impurities but targeting protein buildup and microscopic debris that can interfere with proper adhesive bonding.

This step is especially important for clients who wear heavy makeup regularly or have oily skin—both of which can stimulate excess keratin production and lead to buildup around the lash line and eyelid crease.

Once the protein remover has done its job—eliminating stubborn residue and protein buildup—it leaves behind a truly clean, residue-free lash surface. As a result, the adhesive bonds directly to the natural lash rather than to leftover impurities. This leads to stronger retention, improved adhesion, and a reduced risk of premature lash shedding.

How to Use Protein Remover:

1. Dispense a small amount onto a microfiber brush.

2. Gently swipe along the natural lashes, focusing on the lash line.

3. Allow to dry completely before applying primer or adhesive.

Pro Tip: 

Use just enough product to cleanse—over-saturating the lashes can delay adhesive curing or lead to lifting.

Step 3: Lash Primer

Once the lashes are clean and free of oil and protein buildup, the next step is applying a lash primer. This essential liquid helps remove any remaining dust or residue, ensuring the natural lashes are as clean and prepped as possible for optimal bonding.

But what makes lash primer different from a protein remover—and why is it still necessary? While both contain mild cleansing agents, such as alcohol, the primer’s primary role is not just cleaning. Its key function is to enhance adhesive bonding. Applied after the protein remover, primer removes residual moisture, balances the natural lashes' pH, and initiates a chemical reaction that improves the adhesive’s grip and performance. By applying primer to a lash base that’s already been properly prepped, you’re setting the stage for maximum retention, faster curing, and healthier lash wear—all without compromising comfort or safety.

How to Use Lash Primer:

1. Apply a small amount of primer to a microfiber brush or lint-free applicator.

2. Gently dab or swipe along the natural lashes, focusing on the mid-length to base.

3. Avoid oversaturation and contact with the skin or lash roots.

4. Allow the primer to air dry completely before proceeding with the application.

Pro Tip: 

Primers are especially beneficial for clients with oily skin or when lashing in high-humidity environments, as they help create the ideal bonding conditions. By balancing moisture levels and preparing the lash surface, primer ensures stronger retention and consistent results—regardless of external factors like oil production or weather.

Step 4: Glue Accelerator

Now comes the final step in the lash pre-treatment routine—and your last chance to fine-tune adhesive performance: Glue Accelerator.

This liquid is specially formulated to speed up the curing time of lash adhesive by enhancing the chemical reaction between the glue and ambient moisture. The result? A faster bond that locks in fan shapes instantly, prevents unwanted fan closure, and boosts efficiency without causing curing shock. No more waiting—just super-fast curing, stronger attachment, and smoother workflow. That means:

• Shorter application times

• Increased client satisfaction

• Higher daily appointment capacity

• Better overall retention

By accelerating the bonding process, Glue Accelerator doesn’t just save time—it also enhances bond strength, giving your clients longer-lasting results.

Pro Tip: 

Glue accelerators are especially useful in low-humidity environments or when working with slower-drying adhesives. They help reduce stickiness, speed up attachment, and improve overall efficiency—making them a go-to tool when creating volume and mega volume sets.

Adhesive Application:

Step 5: Ultra Bond Adhesive

You can’t confidently talk about eyelash extensions without mentioning the eyelash adhesive. As the name suggests, it's the core product that bonds each false lash to the natural lash—and it plays a critical role in both retention and client comfort.

With so many adhesives on the market—each offering different formulas, dry times, and performance levels—it’s essential for every lash artist to choose a high-quality adhesive that matches their technique, speed, and environment. The right adhesive doesn’t just hold lashes in place—it builds the foundation of a successful, long-lasting lash set.

At Lii Lash, our Ultra Bond Adhesive is a best-seller, trusted by professional lash artists for its fast adhesion, strong hold, and reliable performance in a wide range of conditions. Whether you're working in low or high humidity or applying classic or volume lashes, Ultra Bond delivers a seamless bond that keeps fans open and extensions locked in for weeks.

• 0.5–1s Drying Time

• Thin, Water-Like Viscosity

• Low-Fume

• Deep Black Finish

• Suitable for All Techniques

How to Use Ultra Bond Adhesive:

1. Remove the cap and insert the glue pin.

2. Shake for 1 minute to fully mix the ingredients.

3. Dispense a small amount into a glue ring or tile.

4. Dip to form a glue bead, then place directly onto the natural lash. No swiping.

5. After use, “burp” the bottle to release trapped air and prevent clogging.

Post-Adhesive Care:

Step 6: Super Bonder

Beyond pre-treatment, there’s one more essential liquid that has become a favorite among lash artists during post-care: Super Bonder.

Once the application is complete and the adhesive has begun to set, Super Bonder is applied to the base of the extensions to instantly seal the bond. This step helps prevent early weakening or breakage before it occurs. By curing the adhesive from the outside in, Super Bonder reduces the full curing time from 24 hours to just 3—allowing clients to get their lashes wet much sooner, without risk.

In addition to improving retention, Super Bonder forms a protective barrier around the glue, helping to minimize fumes that can cause irritation or discomfort for both the client and the artist. The result? Stronger lashes, happier clients, and a smoother overall experience.

• Locks in long-lasting adhesion

• Reduces curing time to 3 hours

• Odor-free for 24 hours

• Maximize lash retention

How to Use Super Bonder:

1. Apply 1-2 drops onto a microfiber brush.

2. Gently apply to the bottom 2–3 mm of the lash set.

3. Allow to dry for 2 minutes.

Pro Tip: 

Always allow the lash adhesive to dry for 2–3 minutes before applying Super Bonder. Applying it too soon—while the adhesive is still wet—can trigger a chemical reaction that disrupts bonding, causes irritation, or even leads to lash extension failure.

Think of this pause as part of your rhythm. Just like every other liquid step, a short wait ensures each product works at its best—and your retention stays flawless.

Step 7: Cream Remover (For Extension Removal)

While applying eyelash extensions is an art, removing them properly is a responsibility. Once a client has fully enjoyed their set and is ready for a break—or preparing for a fresh new application—this is when Cream Remover becomes essential.

Specially formulated for safe, gentle removal, this creamy, non-drip solution effectively breaks down lash adhesive without causing irritation or harming natural lashes. Unlike liquid removers that may run or sting, our Strawberry Scented Cream Remover stays exactly where it’s applied—providing better control and safer results, especially for clients with sensitive eyes or skin.

• Fast, non-irritating removal

• Damage-free & hydrated lashes

• Thick & creamy texture for precise application

How to Use Cream Remover:

1. Apply an under-eye patch.

2. Use a microfiber brush to apply remover on bonds.

3. Wait 5–10 mins, then gently remove extensions.

4. Rinse lashes with water to remove residue.

5. Cleanse with lash shampoo.

Bond Beyond the Basics: Finishing Strong With Liquid Mastery

When it comes to flawless lash extension results, technique alone isn’t enough—the right liquid routine is what sets the foundation for true, long-lasting retention. From gentle cleansing and proper priming to bond-boosting accelerators and post-application care, each step plays a crucial role in supporting lash health, client comfort, and adhesive performance.

Whether you're a seasoned lash artist or just starting your journey, mastering your liquid lineup gives you greater control, stronger results, and happier clients. Invest in quality, use each product with purpose, and let every set reflect your precision and professionalism.
