What is the shelf life of unopened eyelash glue
The unopened shelf life of eyelash glue depends on whether it contains solvents:
Eyelash glue containing solvents: The unopened shelf life is typically between 3 to 6 months. Over time, solvent-containing glue will gradually solidify and become viscous, so it is recommended to use it within one month of opening. Once exposed to moisture in the air, even solvent-containing glue will begin to solidify.
Solvent-free eyelash glue: The unopened shelf life is longer, usually around 3 years. Even if expired, this type of glue will not solidify like solvent-containing glue, but its adhesive strength may decrease.
It is important to note that regardless of whether it has been opened, all types of eyelash glue may gradually lose their stickiness when exposed to moisture in the air, so prolonged exposure should be avoided.
