How should opened eyelash adhesive be stored?

Storing opened eyelash adhesive in a cool and dark place is essential for maintaining its effectiveness and longevity. Adhesive products for eyelashes contain components that can degrade when exposed to heat and light, leading to a reduced bonding strength and a risk of clumping or hardening.

A cool temperature helps to slow down the chemical reactions that can occur in the adhesive, preventing it from thickening or losing its properties prematurely. Darkness is also important because UV light can break down the ingredients in the adhesive, again affecting its performance.

In contrast, storing the adhesive in a humid environment or direct sunlight could lead to contamination, accelerated breakdown, and compromised effectiveness. Room temperature storage might be acceptable in some cases but does not provide the extra protection from light and heat that a cool, dark environment does.
