What environmental factor is essential for the curing of eyelash extension glue?

Moisture, or humidity, plays a crucial role in the curing process of eyelash extension glue. Most adhesive formulas used in eyelash extensions are cyanoacrylate-based, which means they require moisture in the air to initiate the curing process. When the glue is applied, it reacts with the humidity present in the environment, causing the adhesive to bond the eyelash extensions to the natural lashes effectively.

In low-humidity conditions, the curing process can slow down, leading to inadequate bond strength and potentially causing the extensions to fall off sooner. Therefore, maintaining an appropriate level of moisture is essential for ensuring that the extensions adhere properly and last for the expected duration.

While air circulation, heat, and darkness may influence other aspects of the eyelash extension process, they are not as critical as moisture for the proper curing of the glue.
