The Differences Between Pre-treatment lash products

In the world of professional eyelash extensions, achieving flawless, long-lasting results isn’t just about the lashes or adhesive—it’s also about the supporting products that prepare, enhance, and secure the bond. Among the most essential yet often misunderstood are three Pre-treatment lash products lash primers, accelerators, and boosters.

At CharmLash, a top global manufacturer of premium eyelash extensions and lash care products from Vietnam, these three solutions have been formulated with precision to support every stage of the lash extension process. But what do each of them actually do? And how do they differ?

This in-depth guide explores the differences between CharmLash Primer, Accelerator, and Booster, helping lash artists—from beginners to seasoned professionals—optimize retention, reduce application time, and deliver consistently exceptional results.

Understanding the Role of Pre-treatment lash products

Before diving into the differences, let’s look at the role each of these products plays in the eyelash extension process.

All three are pre-treatment or mid-treatment enhancers, but they target different issues—from oil removal and pH balancing to speeding up adhesive bonding.

CharmLash Primer: Deep Cleaning for Perfect Adhesion

What is it?

The CharmLash Primer is a lash cleanser used before lash extension application to remove dust, oil, makeup residue, and protein from the natural lashes. Think of it as prepping a canvas before painting.

Key Features

• Fast-drying, water-based formula.
• Gentle yet effective cleansing without irritation.
• Designed for all lash types.
• Balances moisture without over-drying.

How it works

Lash adhesives work best when applied to a clean, dry surface. Any leftover oil or residue can create a barrier, making it harder for the glue to bond and resulting in poor retention. The primer eliminates this issue.

By thoroughly cleansing each lash, the primer ensures that glue sticks directly to the lash surface, not to debris.

When to use it?

• Before every full set or refill.
• Especially useful for clients with oily skin or makeup residue.
• For those experiencing poor retention or adhesive slippage.

Application Steps

1. Dispense a small amount onto a microfiber brush.
2. Gently apply to clean, dry lashes from root to tip.
3. Allow a few seconds for it to dry completely before continuing.

Pro Tips

• Use sparingly—too much can over-saturate the lashes.
• Combine with a lash shampoo for best results.

Summary

CharmLash Primer is your first defense against poor retention, setting the stage for optimal bonding by giving adhesive the best possible surface to cling to.

CharmLash Accelerator: Speeding Up Bonding Time

What is it?

The CharmLash Accelerator is a pre-treatment liquid that speeds up the drying (polymerization) of lash adhesive. It does not clean or prep like primer but works chemically to make the glue bond faster once it touches the natural lash.

Key Features

• Designed to reduce curing time of all types of lash adhesives.
• Perfect for high-humidity or fast-paced environments.
• Contains ingredients that balance pH and gently open hair cuticles for better adhesion.

How it works

Most eyelash adhesives cure when exposed to moisture (humidity). The accelerator interacts with the moisture in the air and on the lashes to stimulate faster glue curing. This means:

• Faster application
• Less glue travel or blooming
• Better lash placement and control

For lash artists working with fast-drying glue or in a warm, humid room, this can be a game changer.

When to use it?

• On clients with oily lashes where glue bonding is slow.
• In high-humidity or high-temperature salons.
• When using slower-curing adhesives that need a boost.
• During volume or mega volume sets where glue exposure is high.

Application Steps

1. Apply a small amount with a microbrush on natural lashes after primer.
2. Allow 30 seconds for absorption.
3. Continue with lash extension application.

Pro Tips

• Do not overuse—excess product can lead to brittle bonds.
• Store in a cool, dry place to maintain formula stability.

Summary

CharmLash Accelerator is ideal for reducing application time and ensuring faster glue bonding, especially in challenging conditions. It’s like giving your adhesive a turbo boost—without changing the glue itself.

CharmLash Booster: The Retention Maximizer

What is it?

The CharmLash Booster is designed to enhance glue bonding by altering the pH level of natural lashes and lash extensions. It prepares both the natural lash and the extension base for maximum adhesive grip.

Key Features

• pH-balancing formula enhances adhesion and retention.
• Applied on the lash strip or natural lashes.
• Helps adhesive cure evenly and deeply.
• Prevents “sliding” of extensions post-application.

How it works

The booster adjusts the lash pH to the optimal level (slightly alkaline), opening the hair cuticle. This makes the lash surface slightly rougher, allowing the glue to grip better.

It’s especially helpful when you experience:

• Glue slipping from the lash base
• Extensions popping off during brushing
• Inconsistent bonding strength

Unlike the primer or accelerator, the booster can be applied directly to the lash extensions on the strip—making it ideal for prepping your lash fans too.

When to use it

• For volume or mega volume sets.
• When fans are not gripping well to the natural lash.
• Clients with notoriously short retention cycles.
• On both the natural lashes and the lash strip for dual enhancement.

Application Steps

1. Dab a small amount of booster onto a microfiber brush.
2. Apply on natural lashes or lash strip bases (not both if unsure).
3. Let it dry for 30–60 seconds before proceeding.

Pro Tips

• Use it with high-viscosity glues for better results.
• Great for advanced artists working with handmade fans.

Summary

CharmLash Booster is your secret weapon for unbeatable retention, especially in volume applications or when glue grip is inconsistent.

Key Differences at a Glance

Choosing the Right Product Based on Lash Conditions

Let’s explore different client scenarios and which CharmLash product best suits each:

🧴 Oily Skin or Makeup Residue

Can You Combine All Three?

Yes—but only if you understand the role of each product.

Safe Sequence:

1. Primer – Clean the lashes.
2. Accelerator – Speed up curing.
3. Booster – Increase bonding strength.

Just be cautious:

• Don’t over-saturate the lashes.
• Let each layer dry completely before adding the next.
• Use very small amounts (these are concentrated formulas).

Final Thoughts: Elevate Every Set with Strategic Pre-Treatment
