Which Lash Glue Is Right for You? Compare Aquila, Azure & Speed Formulas

Ask ten lash artists for the “best lash glue” and you can get ten completely different answers.

That does not mean nine of them are wrong. It usually means they work at different speeds, in different rooms and with different habits.

The best adhesive is not the fastest one or the one getting talked about most in a Facebook group. It is the one that gives you enough working time to make a clean attachment in the temperature and humidity you actually work in.

Before you buy another bottle hoping it fixes retention, check two things: your room conditions with a hygrometer, and how quickly you genuinely move from dip to attachment. Those two answers narrow the choice down very quickly.

Compare the LashJoy lash glues

Do not choose from the set-time column alone. A 0.3-second glue is only an upgrade if you can consistently get the extension into final position before it starts setting.

Aquila Low: more working time, less rushing

Aquila Low is our original Aquila formula. It works best around 22–25°C and 35–55% humidity, with a set time of roughly 1–4 seconds depending on conditions.

We like it for artists who want enough time to isolate, dip, place and make sure the base is actually sitting where it should. That includes newer artists, but it is not a “beginner glue”. Plenty of experienced artists simply prefer a little more control.

Fast glue is not a badge of honour. If a slower formula gives you cleaner attachment and more consistent work, it is the better glue for you.

Aquila Medium: when your room naturally runs warmer or more humid

Aquila Medium also sits around a 1–4 second set time, but it is designed for approximately 23–27°C and 50–70% humidity.

This is where we see artists overcomplicate things. Their room naturally sits at 25°C and 60% humidity, but instead of choosing a glue that suits those conditions, they spend all day fighting the air-conditioner and dehumidifier to force the room into another formula's range.

Control the room where it is sensible, but do not make your life harder than it needs to be. If your salon naturally runs warmer and more humid, the adhesive designed for that range is usually the smarter starting point.

Some artists keep both Aquila formulas and switch as their room changes through the year. That makes much more sense than pretending Brisbane in February behaves like Brisbane in July.

Azure 0.75s: fast without jumping all the way to 0.3 seconds

Azure 0.75s works around 20–25°C and 20–65% humidity, with an approximate set time of 0.75–1 second.

The formula appears blue in the bottle and cures clear, with no carbon-black pigment. It is a good fit for experienced artists who genuinely work quickly but still want more breathing room than Speed gives them.

If you are regularly waiting for Aquila to grab, your room is in range and your attachment is already clean and consistent, Azure can be a logical step faster.

Speed 0.3s: only when you are actually that fast

Speed 0.3s is our quickest adhesive. It is designed for very fast artists working below 23°C and up to 65% humidity.

This is not the glue we recommend because someone says, “I want better retention”. If you are still positioning the extension after the adhesive has started setting, going faster can make attachment worse, not better.

A clue is what happens during the set. If extensions are flicking off when you brush through, or you feel as though the glue has grabbed before the base is fully where you want it, your adhesive may be outrunning you.

Speed makes sense when your technique is already quick enough that a slower adhesive is genuinely holding you back.

How do you know if your glue is too fast or too slow?

You do not need to guess from the label. Look at what is happening while you work.

The point is not to diagnose every retention issue from one clue. It is to stop changing products randomly and start looking for a pattern.

Your room matters more than the weather app

Cyanoacrylate adhesive changes speed with temperature and humidity. In general, warmer and more humid conditions push it faster; cooler and drier conditions slow it down.

Measure the conditions where the client is actually lying, not outside and not on the other side of the salon. A hygrometer beside your working area gives you information you can actually use.

Also remember that “inside the recommended range” does not mean the adhesive feels identical at every point in that range. An adhesive at the cool/dry end can feel very different from the same adhesive at the warm/humid end.

That is why we give working ranges rather than pretending a bottle has one fixed speed in every room.

Freshness matters more than artists realise

We treat an opened LashJoy adhesive as a 30-day bottle. Write the opening date on it. Do not rely on remembering when you opened it between clients.

Unopened LashJoy adhesives should be used within their recommended shelf life, which for our range is up to around three months. Once a bottle is opened, keep it upright, tightly sealed and away from heat and moisture. Do not put an opened bottle back in the fridge.

Your working drop also changes while it sits exposed. Refresh it before it becomes thick or tacky. If you work from LashJoy Adhesive Cups, the separate chambers make it easy to move to a fresh drop during the appointment instead of stretching one drop for too long.

Do not make your glue responsible for every retention problem

A good adhesive still needs clean natural lashes, enough product, full attachment and decent client aftercare.

If one client has poor retention while everyone else from the same week is fine, changing your glue is usually a poor first move. If five clients from the same few days all have the same issue, that is very different. Look for what those appointments had in common.

Our 25 Reasons Your Client's Lash Retention Is Suffering gives you a much broader troubleshooting checklist when the problem is bigger than adhesive choice.

Still choosing between two LashJoy glues?

Start with three questions: What is the temperature in my lash room? What is the humidity? How quickly can I consistently isolate, dip and make full attachment?

If you want more working time, start with the Aquila formula that matches your room. If you are genuinely fast and Aquila feels too slow, look at Azure. If Azure is still holding you back and you are already placing almost immediately, Speed may make sense.

If the bigger issue is inconsistent retention rather than choosing between bottles, our Lash Retention 101 course goes much deeper into prep, application, client factors and troubleshooting.

And if you are still unsure, ask us. Tell us your room conditions and how quickly you work. That is far more useful than simply asking which glue is “best”.
