Shock curing, and how to avoid it

Early in my career I learned the hard way how lash remover reacts when water gets involved. It turns back into a liquid form and then, shock cures. The adhesive goes from liquid to solid white glue in seconds, and suddenly you’ve got blooming where beautiful bonds should be.

What shock curing actually is

Technically called shock polymerisation, it happens when cyanoacrylate adhesive hardens too rapidly due to excessive moisture or humidity. The result is a weak bond and the tell-tale white residue we call blooming.

The four main causes

• High humidity in the workspace, anything over 60% can be risky.
• Client eye watering during application.
• Improper nano mister use, too close, too much, too soon.
• Poor adhesive storage, temperature swings and exposure to moisture degrade it fast.

How to prevent it

Keep your workspace in the optimal humidity range for your adhesive. Store glue somewhere cool, dark, and dry, never the fridge, unless it’s sealed in an airtight container. Use the smallest drop of adhesive you can. Watch for client eye watering and blot gently. Prime the lashes properly to maximise retention and minimise moisture interference.

During removal

Don’t introduce excess moisture when you remove a set. Cleanse with dry microfibre applicators in the right sequence, and never let water get near the remover itself.

If it does happen, the fix

Gently remove the affected extensions using the banana peel method, then reapply fresh ones. Don’t try to salvage blooming, the bond is compromised and the client deserves the set they booked.
