Coating sealant vs. Super bonder

In the world of lash extensions, achieving optimal results hinges on using the right products. Lash artists strive to meet their clients' expectations by providing the best experience with suitable products and techniques. However, navigating the array of lash tools and solutions can be confusing. A common question that often arises is whether to use a super bonder or a sealant. This comprehensive guide aims to demystify the differences between lash bonders and sealants, empowering you to make informed decisions for flawless lash application.

Super Bonder

Lash bonders play a crucial role in the lash application process. They act as the adhesive that secures lash extensions to the natural lashes. These fast-acting solutions come in various types, each with its unique properties:

  • L-Arginine: This is an amino acid that helps the body produce nitric oxide, which improves blood circulation. It's possible that L-Arginine is included to improve blood flow to the eyelash follicles, potentially promoting lash health.
  • Retinyl Palmitate: This is a form of Vitamin A which is important for skin and cell health. It might be included to promote healthy lashes.
  • Citric Acid: Citric acid is commonly used as a ph adjuster in cosmetics. It helps maintain a slightly acidic environment, which is generally considered ideal for many skincare products. For eyelash extensions, it likely helps create a suitable pH for the bonding agent to function effectively.


  • Reduced Irritation: The rapid curing action of lash bonders helps lock in glue fumes, minimizing irritation for your clients.
  • Universal Compatibility: These versatile products work seamlessly with all types of lash adhesives, offering you flexibility in your lash application process.
  • Enhanced Lash Retention (with proper aftercare): By adding elasticity to the adhesive bond, lash bonders can potentially decrease lash breakage, contributing to longer-lasting lash extensions – especially when combined with a proper aftercare routine that includes regular lash cleansing with a dedicated lash shampoo.

Drawbacks :

  • Limited Impact on Retention (without proper aftercare): Bonders do not guarantee longer-lasting lashes, especially if proper client aftercare is not followed.
  • Higher Cost: Compared to sealants, lash bonders tend to be a pricier optio

Sealant Coating

Lash sealants, unlike bonders, are not adhesives. Their primary function is to create a protective barrier between the lash glue and environmental elements like humidity, sweat, and oils. These elements can break down the adhesive bond, leading to premature lash shedding. Sealants come in two main types:

  • Clear Sealants: These offer a discreet barrier, preserving the natural appearance of the lashes.
  • Colored Sealants (Black): These sealants provide a barrier while adding depth and dimension to the lash extensions, creating a bolder look. Additionally, some formulas are enriched with nourishing ingredients to benefit the natural lashes.


  • Prevents Twisting: They can help prevent lash extensions from twisting or turning out of place.
  • Environmental Barrier: Sealants create a protective shield against environmental elements that deteriorate the adhesive bond.
  • Nourishing Options: Some formulas offer the added benefit of nourishing natural lashes.
  • Compatibility: Sealants can be used with various lash types, including Cashmere and volume lashes.


  • Not for Colored Lashes: It's important to avoid using sealants on pre-colored lashes as they can cause the color to fade.
  • Potential for Irritation: Certain sealants can create a sticky surface, leading to discomfort and possible product build-up, especially with thick volume lashes.
  • Limited Impact on Retention: Similar to bonders, sealants do not guarantee extended wear time without proper client aftercare.
  • Professional Application: Applying sealants effectively requires professional skill, making them unsuitable for at-home use.

When to Use Each Product: A Step-by-Step Guide

  • Prep is Key: Begin by ensuring both your client's lashes and all application tools are completely clean and free of makeup, oils, or residue. This allows for the best possible adhesion of both the lash extensions and any lash products used.
  • Lash Application: After thoroughly cleansing the lashes, proceed with the lash application process according to your usual technique, attaching each extension to the natural lash.
  • Bonding Boost (Optional): Once all lash extensions are in place, you can introduce the lash bonder. Apply a very thin layer of the bonder directly over the lash attachment points using a micropore brush. This step helps accelerate the curing time of the adhesive and potentially adds flexibility to the bond, reducing the risk of lash breakage.
  • Seal the Deal: After the lash bonder has cured according to the product's instructions (usually a minute or two), apply the lash sealant. Similar to the bonder, use a micropore brush to gently coat the lash line where the extensions meet the natural lashes. The sealant acts as a protective barrier, potentially extending the lifespan of the extensions by shielding them from elements like water, sweat, and oils that can break down the adhesive.
  • Drying Time: Allow the lash sealant to dry completely before allowing your client to open their eyes. This usually takes just a few minutes. Following these steps will ensure a secure and long-lasting lash application with the added benefits of lash bonders and sealants.

Learning deeper about the lash world does take dedication but it's guaranteed a worthwhile investment in your skills and your long-term career. You'll work faster, waste less product, and create show-stopping lashes that keep clients coming back for more.
