What is the recommended usage duration for opened bottles of eyelash adhesive?

The recommended usage duration for opened bottles of eyelash adhesive is generally considered to be 5-6 weeks. This timeframe is crucial for ensuring optimal performance and safety of the adhesive. After the bottle is opened, exposure to air can start to degrade the adhesive's quality, impacting its effectiveness in bonding eyelash extensions to natural lashes.

Using the adhesive within this recommended period helps to maintain the desired viscosity and bonding properties, reducing the risk of adverse reactions or poor retention of the extensions. Additionally, adhesives can have specific storage requirements, such as being kept in a cool, dark place, which also contributes to maximizing their shelf life and performance.

This aligns with safety standards in the beauty industry, where the integrity of the materials used is paramount for the health and satisfaction of clients. Following these guidelines can help professionals ensure that the products they use are effective while upholding the highest standards of client care.
