It's genuinely alarming how many lash glue brands list only 2 or 3 vague ingredients like “cyanoacrylate, PMMA, carbon black” and stop there.
Here’s why that’s dangerous and misleading:
1. The stabiliser is critical – It controls how the glue sets, how long it lasts, and how likely it is to cause reactions. A harsh stabiliser can trigger allergies or sensitivities over time, even if everything else looks “safe.”
2. “Cosmetic grade” means full disclosure – If a glue is truly cosmetic-grade, it will meet strict UK/EU/US standards — and part of that is transparency. That includes what type of cyanoacrylate, which stabiliser, and other additives (like plasticisers or preservatives).
A Good Glue Label Should List:
The type of cyanoacrylate (ethyl, butyl, alkoxy)
The stabiliser (is it BHA, HQ, or something worse?)
Catalyst like PMMA (polymer strengthener)
Pigments (carbon black or clear)
If your glue only lists 3 ingredients, what’s hiding in the bottle? Transparency should be a baseline, not a bonus
