What environmental factor can affect the consistency of the adhesive used in eyelash extensions?

Humidity is a crucial environmental factor influencing the consistency of the adhesive used in eyelash extensions. The chemical composition of eyelash extension adhesives often contains cyanoacrylate, which is sensitive to moisture levels in the surrounding air. High humidity can accelerate the curing process, meaning the adhesive sets more quickly, which can complicate application. Conversely, low humidity may slow down the curing time, potentially leading to issues with adhesion and longevity of the extensions.

Maintaining an appropriate level of humidity is vital for achieving the desired performance from the adhesive, ensuring a smooth application process and the durability of the extensions. It's essential for technicians to be aware of the humidity levels in their workspace and how they could impact the application of eyelash extensions.
