Currently, the best material available for the eyelash adhesive bottle is so-called PE, a breathable plastic that allows a minimum amount of air to enter the eyelash adhesive bottle. Prevent the bottle from exploding. However, since PE still allows air to enter the bottle, the adhesive is always in the “hardening in progress” phase and continues to deteriorate even if it has never been opened or used. In our experience, if the adhesive was kept upright in a cool, dry area, 4 months is the maximum period of time during which the unopened adhesive shows its best quality.
If storage conditions are not ideal, the expiration date of the unopened adhesive may be as short as 2 months. Also, keep in mind that sensitive adhesives tend to expire faster than regular adhesives. That's why it's important to know the manufacturing date of eyelash glue, and buying glue “fresh out of the lot” is crucial to the quality of the glue. This deterioration of eyelash glue continues in its “progress” phase from the moment the eyelash glue is bottled, since air cannot be prevented from entering the bottle.
When an eyelash glue is manufactured and bottled, it is inevitable that it will be exposed to air and begin to deteriorate (%3Dde hardened%3D%3D dried). We only produce the minimum amount of glue per batch to ensure the freshness and the best quality of the glue for eyelash extensions. Learning to put them on correctly definitely takes practice, but removing eyelash glue in order to remove them isn't that complicated. Rub your eye with another cotton ball dipped in makeup remover to make sure there's no glue left on the eyelid.
Eyelash extensions are made of PBT, the material itself does not expire, but over time, eyelash curls may lose their shape. If you want to know the manufacturing date of your eyelash glue, you should contact the supplier with this number. Generally speaking, when the glue shows changes in consistency, performance or separation of ingredients, even after you've shaken it before each use, it's time to open a new eyelash adhesive. If you don't do as many sets per month, buy eyelash glue the size of 3 ml with 120 drops of glue, such as BL Ultra Plus Glue 3g, instead you can do about 60 sets in a month after the “open expiry watch”.
No matter what brand of eyelash glue you use, it's important to maintain consistent humidity and temperature. By doing so, you soften the eyelash glue and also remove any particles of dirt or persistent bacteria that haven't been removed during the makeup removal process. Currently, the best material available for an eyelash glue bottle is so-called PE, a breathable plastic that allows a minimum amount of air to enter the eyelash glue bottle.
