🧪 Understanding Lash Glue Allergies — Real Talk From a Lash Artist
At Ladybug Lashes, we're all about safety and results. That’s why we only use cosmetic-grade lash adhesives — no shortcuts, no sketchy chemicals. These formulas are created with your skin, health, and eye area in mind. But let’s get real — even the cleanest glue won’t work for every client.
Here’s what you need to know if you’ve ever had a client suddenly react to your glue, even when you're using the good stuff. 👇
🔍 What Causes Lash Glue Allergies?
Allergies to lash adhesives are more common than most artists realise, and they’re not always caused by the glue you're using today. Clients could’ve had previous exposure to poor-quality adhesives — maybe from a nail salon or another lash tech using industrial-grade glue. That kind of exposure builds up sensitivity over time.
Let’s break down the usual suspects:
1. Cyanoacrylate – The Base of ALL Lash Glues
Cyanoacrylate is what makes lash glue… well, glue. It’s what helps our extensions actually stay on. But here's the kicker: even so-called “cyanoacrylate-free” glues still contain other acrylate compounds — and if someone’s allergic to one, chances are they’re reactive to others too.
💡 Pro tip: Ask your client if they’ve ever had a nail allergy — red, itchy, swollen fingers after getting acrylics or gel nails. That’s a big hint they may have an acrylate sensitivity.
2. Carbon Black – The Pigment in Black Glues
If your client has reacted to mascara or eyeliner, carbon black might be the trigger. If not? It’s probably safe — but if you’re unsure, switch them to a clear adhesive and monitor their reaction.
3. Stabilisers – The Hidden Troublemakers
Stabilisers keep lash glue from breaking down too quickly. But not all stabilisers are created equal — some are highly allergenic, and unfortunately, many suppliers don’t even list them.
Here are a few big no-no’s we avoid like the plague:
🚫 Ingredients to Avoid in Lash Adhesives
🔥 Hydroquinone
-
Banned in some cosmetics.
-
Can trigger severe allergic reactions.
-
Still pops up in some lash glues because lash products aren’t always regulated like traditional cosmetics.
⚠️ Polyisocyanate
-
Found in industrial adhesives.
-
Can cause respiratory issues, skin irritation, asthma, and even chemical pneumonia.
-
This stuff should never be near the eye area — ever.
🚫 N-Methyl-2-pyrrolidone (NMP)
-
Linked to fertility issues and developmental problems in animals.
-
Should be nowhere near a pregnant client (or anyone, really).
-
Used because it’s cheap, not because it’s safe.
❌ Phthalic Anhydride
-
Can trigger allergic reactions, skin rashes, and breathing issues.
-
Also tied to reproductive harm — no thanks!
🧴 So, What Do We Use?
We’ve spent over two years researching safer alternatives — and landed on BHA as our stabiliser of choice.
💡 BHA (Butylated Hydroxyanisole) is approved for use in cosmetics globally and offers reliable glue stability without the harsh side effects. It’s gentler on the eyes and skin, and we’ve seen a massive drop in reactions since switching to it.
✅ How We Go Above and Beyond
Unlike many lash glues on the market, ours actually meet full cosmetic safety standards — even though they’re not legally required to. That means:
-
Transparent ingredient listings
-
Global compliance across major markets
We’re not just throwing around the word “safe” — we’re backing it with science, testing, and ethical choices.
🌍 Trusted Worldwide
From new artists to seasoned pros, lash techs around the world trust Ladybug Lashes to deliver reliable results without compromising on safety. Our glues aren’t just lash-friendly — they’re client- and artist-friendly, too.
💬 Final Word
If you've ever had a client react and couldn’t figure out why — you’re not alone. Allergies are complex, and not your fault. But being educated, asking the right questions, and using truly safe, cosmetic-grade adhesives makes all the difference.
Choose wisely. Ask questions. Demand transparency.
Because great lashes should never come at the cost of your client’s health.
