    If you're facing retention struggles, the culprit isn't always your glue; it's often the preparation and finishing steps.

    Is this product right for me?

    Who is the Retention DUO for? 

    This duo is an absolute must-have for professional lash technicians who want to eliminate the guesswork of lash retention. It is ideal for those working in fluctuating environments or with clients who have difficult natural lashes or active lifestyles.

     

    What is the Retention DUO? 

    It is a high-performance kit containing two full-size essentials: Retention & Speed Booster, which preps the natural lash for an instant grip, and Superbonder Sealant, which cures the adhesive instantly at the end of the set.

     

    When should you use it? 

    Use the Booster as your final pre-treatment step (after Cleanser and Primer) to prepare the lashes for application. Use the Superbonder at the very end of the treatment, once the set is complete, to lock everything in place.

     

    Why choose this DUO? 

    Because it addresses retention from both ends of the treatment. The Booster opens hair cuticles to create a "magnetic" attachment that speeds up your work, while the Superbonder adds elasticity to the glue bonds so they don't become brittle or snap off prematurely.

     

    For the ultimate long-lasting set, follow these professional steps:

    • Pre-application: Apply a small amount of Booster to the natural lashes with a microfiber brush. This opens the cuticles, allowing the glue to "grab" instantly without having to hold the extension in place.
    • Post-application: Once the set is finished, wait 2 minutes and apply a tiny drop of Superbonder to the adhesive zone (the base). This instantly polymerizes the glue and locks in fumes.
    Description

    The Retention DUO optimizes the chemical bond of your lash adhesive from start to finish.

    • Primary Benefit: 30% cost saving and significantly improved lash retention.
    • Booster Effect: Alkaline pH opens cuticles for "magnetic" attachment.
    • Superbonder Effect: Instant polymerization, reduces irritation, and adds bond elasticity.
    • Client Safety: Eliminates the 24-hour "no water" rule; lashes can get wet immediately.
    • Formula Update: Effective results guaranteed (Superbonder updated June 2025).
    • Bundle Opportunity: This is our most popular value pack for solving retention issues in one go.
    • Shelf Life: Superbonder (24 months before opened; 6 months once opened); Booster (18 months before opened; 3 months once opened)
    FAQs

    How should my clients clean their lash extensions?

    We always recommend advising clients to use a professional lash cleanser specifically formulated for the delicate eye area and safe for eyelash extensions.

     

    Our Lash Foam Cleanser is designed to:

    • Gently remove makeup, oil, and daily buildup
    • Keep lashes clean without compromising retention
    • Help extensions last longer between fills
       

    Using products not designed for lash extensions (like baby shampoo) can lead to dryness, irritation, or poor retention, as they are not formulated for the eye area or adhesive bonds.

     

    For clients with sensitive skin or sensitivities to Tea Tree, a gentle, alternative foaming cleanser is recommended.

    To support your clients further, consider providing digital aftercare guides so they can maintain their lashes correctly at home.

     

    My client’s lashes look clean, but retention is still poor — why?

    Even when lashes appear clean, residue such as oils, skincare, or microscopic buildup can still be present and affect retention.

    If you’re experiencing retention issues:

    • Review your full pre-treatment routine
    • Ensure each step is completed thoroughly
    • Double-check your adhesive is being used within its recommended conditions
       

    Also, client aftercare plays a huge role — improper cleansing or exposure to oils can reduce retention significantly.

     

    What’s the difference between Booster and Superbonder?

    Both products improve retention, but they work in completely different ways:

     

    Booster (Retention & Speed Booster):

    • Applied to the lash strip only (never natural lashes)
    • Speeds up adhesive curing
    • Helps prevent fans from closing
    • Improves control during volume application
    • Supports stronger retention

    Superbonder:

    • Applied after the treatment is complete
    • Increases adhesive flexibility to reduce breakage
    • Seals in fumes to reduce irritation and sensitivity
    • Allows lashes to get wet immediately after treatment
    • Enhances overall retention
       

    What’s the difference between Cleanser and Primer?

    Both are essential for proper lash preparation, but they serve different purposes:

     

    Cleanser:

    Alcohol-based formula
    Removes oils, proteins, and residue from natural lashes
    Deep cleans the lash surface
     

    Primer:

    Water-based formula
    Rehydrates lashes after cleansing
    Balances pH levels
    Prepares lashes for optimal adhesive bonding

    Using Cleanser alone is not recommended. Because it removes moisture, skipping Primer can lead to poor curing and reduced retention.

     

    What pre-treatment routine gives the best retention?

    A consistent, thorough pre-treatment routine is key to long-lasting results. In many cases, retention issues come down to prep — not the adhesive.

     

    Recommended routine:

    1. Cleanse the lashes: Use a lash foam cleanser to remove makeup and surface debris
    2. Use Protein Remover Pads: Remove any remaining oils or residue around the lash line
    3. Apply Cleanser: Deep cleanse to eliminate any final traces of oil or product
    4. Apply Primer: eintroduce moisture and balance the lashes for optimal bonding
    5. Use Booster (on lash strip only): Speed up curing and improve application control

      A proper prep routine can make a significant difference in retention and overall results.

     

    Can I use only a cleanser before applying lashes?

    For best results, we recommend completing the full pre-treatment routine rather than relying on Cleanser alone.

    Cleanser removes oils effectively, but it also dehydrates the lashes. Without restoring moisture using a Primer, the adhesive may cure too slowly
    the bonding may be compromised and retention can suffer.
     

    Using both Cleanser and Primer ensures the lashes are properly balanced and ready for optimal adhesion.

    New formula???

    I just got my shipment and I’m glad they aren’t half missing anymore from evaporation I’m assuming but now it doesn’t work… the booster use to be essential for helping the glue not creep up the fan but now it’s doing it… I am devastated if this is the new formula

    Hi Teresa,

    Thanks for your review. We are so sorry to hear you're not happy with the Booster! This doesn't sound right at all. We have now reached out to you via email so we can look into this further.

    Thank you so much.

Thank you so much - LLP x

    The super-bonder, for the send time in a row, was only filled about halfway. No issue with the booster.
