Lash Primer vs Super Bonder: What to Use and When

Apply a lash primer for extensions after cleansing and before placing extensions. Assess the lashes first and follow the preparation system used for the service.

COMELYLASH GP1 Eyelash Primer is intended to help soften natural lashes to support faster application. Its directions call for a small, even application followed by drying before extension placement. Cleanse the lashes before using GP1.

2.1 When to use lash primer

Consider GP1 when your preparation system calls for primer and you want its stated lash-softening function. Complete cleansing first, then keep the primer application light and controlled. The surface should be dry before extension placement begins.

2.2 How to use lash primer for extensions: COMELYLASH GP1

1. Complete the appropriate lash cleansing and preparation steps for the client.
2. Use a suitable clean applicator to apply a small amount of GP1 evenly to the natural lashes.
3. Keep the application controlled rather than saturating the lash area.
4. Allow the surface to dry before applying extensions.

GP1 does not specify a fixed drying time in seconds. Follow the supplied label and check that the surface is dry before placement.

Apply super bonder to the adhesive bonding points once the set is complete.

COMELYLASH GB1 Super Bonder is used after application to help adhesive cure in approximately three minutes and reduce odor release.

The three-minute description concerns curing support. It is not a stated wait before applying GB1, and it does not establish when a client can wet the lashes. Use the adhesive's and bonder's supplied directions for timing and aftercare.

Super bonder is not lash adhesive. It does not correct poor isolation, an unsuitable glue drop, late placement or an attachment with too little contact. Those problems need to be addressed during the application itself.

3.1 When to use super bonder

Choose GB1 when your adhesive system permits a bonder and you want a defined post-application finishing step. Complete and inspect the set before applying it to the adhesive bonding points.

Reduced odor does not mean a product is fume-free or suitable for every client. Keep the same professional handling and client-assessment standards throughout the service.

3.2 How to use lash bonder: COMELYLASH GB1

1. Finish the lash extension set.
2. Place a small amount of GB1 on a suitable clean applicator.
3. Apply it evenly to the adhesive bonding points.
4. Follow the product directions for the final curing period and aftercare.

Keep the small amount of product at the bonding points; avoid saturating the lashes.

No. Lash cleanser and lash primer can occupy separate steps.

A cleanser is used to remove debris and products from the lash area according to its directions. A professional primer prepares the natural lashes for extension application according to the formula's intended use. Some systems include both steps, while others use a different preparation sequence.

For a COMELYLASH routine, keep the jobs distinct: lash shampoo handles cleansing; GP1 supplies the stated primer step after cleansing. Follow each product’s directions rather than adding extra primer to compensate for incomplete cleaning.

The names are sometimes used loosely across the market, but they should not be assumed to mean the same formula or the same application method.

Check three points on the actual product:

• Whether it is intended for professional extensions or DIY cluster lashes.
• Whether it is applied before, during or after extension placement.
• Whether it is placed on the natural lash, the adhesive bond or another area.

COMELYLASH GB1 is identified as a super bonder for use on adhesive bonding points after professional eyelash extension application. DIY cluster bond and seal products belong to a different service category and are outside this guide.

If a set behaves inconsistently, record the room conditions and application steps before adding another liquid.

Review the following:

• Were the natural lashes clean and dry before application?
• Was the adhesive used within its listed temperature and humidity range?
• Was the glue drop fresh enough for the appointment pace?
• Did each extension have sufficient contact with the natural lash?
• Was placement completed before the adhesive grabbed?
• Did the client receive clear aftercare instructions?

Our lash adhesive humidity and temperature guide explains how to record room conditions and troubleshoot adhesive speed without changing several variables at once.

Place GP1 with your preparation products and GB1 with your finishing products. Check the model name before dispensing: both are clear liquids in 10 ml bottles, but they belong at different points in the appointment.

Both current product listings give a shelf life of 12 months unopened and 6 months after opening. Record the opening date on each bottle and follow the supplied storage instructions. These periods apply to the GP1 and GB1 bottles. Check your adhesive separately for its shelf life.

When reviewing your workflow, keep a record of preparation, adhesive, room readings and finishing steps. Change one appropriate step at a time and compare what happened during application.
