Understanding Shock Polymerization in Eyelash Glue: What It Is and How to Avoid It?

Because they provide thicker, fuller lashes without the everyday fuss of mascara, eyelash extensions have become a popular beauty essential. However, the smooth application conceals a sensitive chemical process that is readily interfered with. Shock polymerisation is an important topic that clients and lash artists should be aware of. What does shock polymerisation in eyelash glue actually mean, and why is it important? 

What Is Shock Polymerization?

The term "shock polymerisation" describes the abrupt and early curing (hardening) of eyelash extension glue brought on by an unanticipated increase in moisture or humidity. The majority of eyelash adhesives are based on cyanoacrylate, a quickly drying substance that creates a strong bond when it combines with ambient water vapour.

This curing process is progressive and regulated under the best circumstances. However, excessive humidity or moisture causes the glue to polymerise too rapidly, creating a fragile bond. Shock polymerisation is the term used to describe this rapid hardening. 

Why Is Shock Polymerization a Problem?

Although rapid drying may seem advantageous, shock polymerisation causes a number of problems:

• Weak or Brittle Bonds: The client may experience discomfort and the extensions may be more likely to shed early if the connection becomes stiff and rigid.
• Poor Retention: Lash loss may occur early due to improper bond formation.
• White Residue (Blooming): Where the glue has hardened too quickly, white, chalky patches may emerge. This is a symptom of shock polymerisation. Another name for this is "blooming" or "frosting."
• Client Discomfort: Increased fumes and possible eye discomfort might result from improper curing. 

What Causes Shock Polymerization?

This quick curing process can be triggered by a few things:

• High Humidity: Lash adhesives function best in a range of regulated humidity, often between 45 and 60 percent. The chemical reaction is accelerated by excessive humidity.
• Direct Water Exposure: Using water-based products or washing the lashes too soon after application might hasten the healing process.
• Inappropriate Use of Nano Misters: The glue may get too wet if you mist it too much or put it too close to the eyes. 

How to Prevent Shock Polymerization

In order to prevent shock polymerisation, lash artists must pay close attention to the application procedure and working environment:

• Manage the Climate in the Room: Use a hygrometer to check the humidity and use a humidifier or dehumidifier as necessary.
• Pick the Correct Glue: Choose adhesives that are appropriate for the humidity levels in your area and, if needed, modify them annually.
• Use Water Sensibly: Apply a little mist and maintain the specified space between micro misters.
• Teach customers: After a fresh set, advise customers to stay away from steam and saunas and not to wet their lashes for at least 24 hours. 

A frequent but avoidable problem with applying eyelash extensions is shock polymerisation. Lash specialists may guarantee their clients more pleasant, long-lasting outcomes by regulating environmental conditions and comprehending the physics underlying the adhesive. Understanding what goes on behind the scenes helps safeguard your lashes and your investment, regardless of your level of experience as a lash artist or your level of curiosity as a customer.
