Eyelash Extension Glues, Adhesives & Liquids Collection

For new lash artists, slower-setting adhesives are easier to work with. Aquila Low or Medium is ideal for beginners due to its 1–4 second dry time. It gives you more time to isolate and place each extension without rushing. Always match your glue choice to your room temperature and humidity for best results.

Store unopened lash glue upright in an airtight container with an oxygen absorber sachet in a cool, dry place (or fridge). Once opened, keep it at room temperature and use within 30 days. Never return opened glue to the fridge—condensation can ruin the formula.

Yes — unopened lash glue can be refrigerated to extend its shelf life. However, before using it, always allow the bottle to return to room temperature (this usually takes about 1–2 hours).

Do not refrigerate lash glue once it has been opened. The repeated changes in temperature (from cold to warm and back again) create moisture buildup inside the bottle. This condensation accelerates the breakdown of the adhesive, causing it to become thick, stringy, and ineffective much faster than usual. Instead, store opened glue in a cool, dry place — ideally in an airtight container with a silica or oxygen absorber sachet.

For best performance, we recommend replacing opened LashJoy adhesives every 30 days. Unopened bottles stay fresh for up to 3 months from purchase when stored properly.

Yes, humidity has a major impact on how lash glue cures. Higher humidity causes the adhesive to cure faster, while low humidity slows the curing process. If your room conditions don’t match the glue’s recommended working range, you’ll likely see issues like poor retention, weak bonds, or stickies.

Take Aquila Low for example:

• At the lower end of its working range (22°C and 35% humidity), it will set closer to 3 seconds.
• At the upper end (25°C and 55% humidity), it can cure in as little as 1 second.

If humidity gets too high, the glue can cure before it fully wraps around the natural lash — resulting in poor bonding. If it’s too low, the glue stays wet longer, increasing the risk of lashes sticking together or shifting out of place.

If your glue becomes stringy or gluggy, it’s likely due to:

• Moisture exposure (from humidity or condensation)
• Not “burping” the bottle after use
• Leaving the cap off between uses
• Expired adhesive (open longer than 30 days)

Always store your glue upright, tightly sealed, and in a humidity-controlled space.

“Burping” releases trapped air after dispensing. Lightly squeeze the bottle, wipe the nozzle with a lint-free wipe, and recap immediately. This prevents air bubbles, clogs, and thickening.

Each glue has a sweet spot:

• Aquila Low: 35–55% humidity
• Aquila Medium: 50–70% humidity
• Azure Low: 20–65% humidity

Working outside these ranges can lead to poor retention or slow curing. Use a hygrometer and humidifier/dehumidifier to keep your lash room in the ideal range.

If your lash adhesive isn’t bonding properly, start with these key troubleshooting steps:

• Check your environment: Make sure your temperature and humidity match the glue’s recommended range. Even a few degrees off can affect curing speed and retention.
• Use a fresh glue drop: Replace your glue dot every 15–20 minutes to ensure optimal performance — especially in warm or humid conditions.
• Double cleanse and prime: Always cleanse the natural lashes thoroughly with an approved lash cleanser, then prime with LashJoy Primer to remove any remaining oils or residue.
• Don’t underuse glue: If your glue is setting slower than usual due to low humidity or cooler temps, it’s tempting to use less adhesive — but this can backfire. Too little glue can weaken the bond and lead to early lash shedding. Stick to your normal dipping technique and adjust your glue choice if needed.
• Check the age of your glue: Lash glue should be replaced every 30 days after opening, even if it still “looks fine.” Old glue = weak bond.
  

✅ Important tip: If your glue has been working well for other clients that day, but suddenly won’t bond on one client — the issue is likely client-related. Sunscreen, moisturiser, or facial oil applied before the appointment may have soaked into the natural lashes and created a barrier. Always ask clients to avoid applying oily skincare products on the day of their lash appointment.

🧪 Still having issues? You may need a glue better suited to your conditions or speed. Try:

• Azure Low for fast setting in low humidity
• Aquila Low for moderate speed and low-to-mid humidity
• Aquila Medium for slower drying in higher humidity

No — we do not recommend using "sensitive" lash glues that contain traditional cyanoacrylate for clients who have experienced a previous allergic reaction or sensitivity. Lash allergies typically worsen with repeated exposure, and continuing to apply extensions in these cases puts your client’s eye health at serious risk.

Remember:

• We only get one set of eyes.
• If a client has reacted once, they’re likely to react again — often more severely.
• Insurance will not cover you if you knowingly apply a product to a client who has previously reacted.

Using a so-called “sensitive glue” doesn’t eliminate the risk — it just delays the inevitable. Most of these glues still contain cyanoacrylate, the same base ingredient responsible for triggering reactions.

💡 The exception: LED lash adhesives are fundamentally different from traditional lash glues because they don’t rely on cyanoacrylate to cure — that’s the main ingredient in most “regular” lash glues (including so-called “sensitive” ones) and the usual culprit behind allergic reactions.

However, even these should only be used after thorough consultation and patch testing under strict conditions. Always follow your insurer's guidelines and prioritise safety.

Instead of cyanoacrylate, LED lash glues use light-cured polymers — typically a blend of:

• Acrylate-based monomers (not cyanoacrylate)
• Photoinitiators (activate the curing process when exposed to LED light)
• Other stabilisers and viscosity modifiers for consistency and bond strength

These adhesives stay in liquid form until exposed to a specific wavelength of LED light (usually around 395–405 nm), which causes an instant chemical reaction to cure the bond.

Retention issues are often caused by poor prep, incorrect glue choice, or unstable room conditions. Start by double-cleansing lashes, using a primer, and working with a glue that suits your environment. Refresh your glue dot every 15–20 minutes and replace open bottles every 30 days. Using the correct technique with a high-quality glue like Aquila Low or Azure Low will improve lash longevity.

After each use, wipe the nozzle with a lint-free wipe to remove residue. Avoid using tissues or cotton products, which can react with the adhesive. Secure the cap tightly to prevent air and moisture from getting in.

Yes. Even if the expiry date hasn’t passed, glue can go off if it’s exposed to heat, air, or humidity. Signs your glue has expired include thick, stringy consistency or poor bonding. Always store unopened glue in an airtight container, and never return opened glue to the fridge.

Lash extension glue is not truly waterproof, but it is water-resistant once fully cured. For LashJoy adhesives, a full cure typically occurs within 4–24 hours, depending on the client's environment and aftercare.

Clients can shower or get their lashes wet after the first 24 hours, though we recommend avoiding direct water pressure, steam, or long swimming sessions during the first few days.

Over time, repeated exposure to chlorine, steam, salt water, and oil-based products can weaken the bond, leading to premature lash shedding. For maximum retention, advise clients to gently pat lashes dry after water exposure and avoid oil-based skincare around the eye area.

Yes. Shaking your adhesive ensures the ingredients are properly mixed. Use a lash glue shaker for 30–60 seconds before your first use of the day, and 10–20 seconds before each new drop. This keeps the consistency smooth and the glue effective.

Using too much lash glue can lead to stickies, lash clumping, slow drying, poor retention, and even damage to the natural lashes. Excess adhesive may also cause the extensions to shift or lift prematurely.

For best results, aim for a small, consistent bead of glue at the base of the extension — just enough to create a strong bond without flooding the natural lash.

If you're noticing lashes sticking together, slipping, or poor hold, it's time to reassess your glue pickup technique.

No. Lash extension adhesives are strictly for professional use only. Applying lash extensions to yourself at home can be extremely dangerous and may result in injury, allergic reactions, or permanent lash damage.

LashJoy adhesives are high-performance, cyanoacrylate-based glues designed for trained technicians who understand safe isolation, proper humidity control, and emergency removal protocols. Using professional lash glue without certification can void insurance coverage and create serious health risks.

If you're looking for a safe DIY option, consider lash serums or temporary strip lashes, but never attempt professional lash extensions at home.
