How long can unopened bottles of eyelash adhesive typically last?

The shelf life of unopened bottles of eyelash adhesive is typically up to 6 months. This timeframe is considered standard for most professional-grade adhesives, as they are formulated to maintain their effectiveness and bonding properties within this period. Factors influencing the shelf life include the type of adhesive, its chemical composition, and storage conditions. Keeping the adhesive in a cool, dark place and avoiding exposure to moisture can help ensure it stays usable for as long as possible.

Understanding the proper shelf life is crucial for lash technicians because using expired adhesive can lead to poor application results, such as weak bonds and possible irritation for clients. Awareness of these details ensures a high standard of safety and quality in lash extension applications.
