Sealer is one of those products that makes way more sense once you know what it is actually doing.
At Pink Rabbit, the Sealer side of Bonded is the finishing step. It helps take away leftover tackiness at the adhesive area and finish the bonded base so your set feels clean and comfortable.
And no, you do not need to paint it through every single lash.
What is lash sealer for?
After you use lash bond, the base can still feel a little sticky. Sealer is what you use at the end to help take that tackiness away and finish the bonded area.
For Pink Rabbit, most of the time you want it at the base, right where the adhesive is.
Tip 1: If you can feel stickiness when you blink, use a little more
This is probably the easiest way to tell where you need Sealer.
Finish your application and blink normally. If one little spot still feels sticky, put a small amount of Sealer right there.
You do not need to coat the whole set because one tiny area is being annoying. Target the spot.
Tip 2: Put a tiny bit inside your tweezers before you clamp
One of our favorite tricks.
If your applicator keeps wanting to stick to the lashes while you clamp, put a very small amount of Sealer on the inside of the tweezers first.
It helps keep the tool from grabbing onto exposed tackiness while you press the lashes together.
Keyword here: tiny. We are lightly coating the inside, not marinating the tweezers.
Tip 3: Keep it at the base if you want fluffy lashes
This is where people can accidentally change the whole finish of their set.
If you brush Sealer through all of the lash fibers, the lashes can start feeling more stiff and defined instead of soft and fluffy.
If fluffy is the goal, keep Sealer mostly at the base where the adhesive actually is.
Tip 4: But you can use that stiffness on purpose
This is the fun part.
If you like a more defined lash look, or you want to create a few spikes in your set, you can use a tiny bit of Sealer on selected fibers and pinch them together.
So brushing Sealer through the fibers is not “wrong.” It just changes the finish.
Keep it at the base for soft and fluffy. Use a tiny amount on selected fibers when you want more definition.
Tip 5: Sealer is not more glue
Bond and Sealer have different jobs.
Bond is the adhesive step. Sealer is the finishing step.
If a segment is lifting because it was never attached properly, piling Sealer on top is not going to magically fix bad placement. Fix the lash first.
Tip 6: Use it after the lashes are placed
For the Double Bond Method, place your segments, press the bases into the natural lashes, then use Sealer where you need it.
If your tool is sticking before your final clamp, that is where the tiny bit inside the applicator trick comes in.
Does sealer cure lash glue?
You will hear people say that sealer “cures the glue.” In everyday lash talk, that usually means it is the finishing step that helps set the bonded area and takes away leftover tackiness.
Different lash adhesives use different chemistry, so we do not want to pretend every sealer works exactly the same way.
For Pink Rabbit, the best way to think about Sealer is this: it finishes the Bonded application, helps reduce tackiness, and seals the adhesive area.
How much should you use?
Very little.
If you are using it at the base, use enough to deal with the bonded area.
If you are putting it on the applicator, use just enough to lightly coat the inside.
If you are making spikes, use the tiniest amount needed to hold the shape you want.
What happens if you use too much?
The biggest thing you’ll notice is the texture of the lashes.
Too much Sealer through the fibers can take away that soft, fluffy finish and make them look more stiff or separated.
If that is the look you want, cute. If not, keep it at the base.
Our favorite ways to use Sealer
- At the base after a Double Bond application
- On a tiny sticky spot you still feel when you blink
- Lightly inside the applicator before your final clamp
- On selected fibers when you want a more defined spike
Quick questions about lash sealer
Why are my lashes still sticky after applying bond?
You may just need a little more Sealer on that specific tacky area.
Can I put lash sealer on my tweezers?
Yes. A tiny amount on the inside of the applicator can help keep tacky adhesive from sticking to the tool while you clamp.
Should I brush sealer through all my lashes?
Not if you want to keep them soft and fluffy. Keep it mostly at the base unless you intentionally want a more defined finish.
Can I use sealer to make lash spikes?
Yes. A very small amount on selected fibers can help hold a spikier, more defined look.
Is sealer the same as lash bond?
No. Bond is the adhesive. Sealer is the finishing step.
