Do lash extensions expire?

The adhesive should last up to three months unopened, if stored properly. The shelf life, or expiration date, of the open adhesive is four to five weeks. If the glue for eyelash extensions becomes fibrous or thick, it's time to cut the ties and replace the bottle. 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. Eyelash glue expires and, once it has expired, you should not use it. Usually, an unopened bottle of eyelash glue will stay good for 3 to 6 months. However, once opened, it should only be used for about a month.

Bonder also creates a protective layer that causes the adhesive to heal much, much faster (so quickly that it is possible to wet the eyelash extensions immediately after the procedure). This means that the eyelash artist must clean the natural lashes before starting to apply them to ensure that the adhesive is adhering to the clean base. If you end up curling your lashes with an eyelash curler, Richardson recommends the type that warms your lashes like a miniature curling iron, such as the Envious Lashes heated eyelash curler. Sabah Feroz, an expert in eyebrow and eyelash extensions at Blink Brow Bar, tells her clients to wash the area around their eyes when cleaning their face and to use an oil-free makeup remover if they have to clean their makeup.

Because your lashes are at different stages of their growth cycle at any given time, the extensions won't all fall out at once, and you may find that gaps start to appear a few weeks after you put them on. If you don't know, you'll place the eyelash extensions with an adhesive so weak that it won't be as durable as it should have been. The main ingredient of eyelash adhesive is usually cyanoacrylate, which means that it can have a fairly long shelf life, especially if stored properly and the correct instructions are followed. After all, fumes are the main reason for the common irritation and allergic reactions that occur due to eyelash extensions.

If you're an eyelash artist and use a clean swab or mascara stick to apply the sealant, the IntelliSeal can last up to 12 months. The lifespan of your lashes will also depend on how well you care for them after applying them, and luckily, there are many things you can do at home to help preserve your appearance. But did you know that your eyelash supplies can also expire? How often do you save a beloved product to try another and then bring out the old product a year later? The time has come to clean up your supplies and update your inventory so you can offer your customers the best products and services of all time. The cost of eyelash extensions can vary greatly depending on your location, the eyelash technician, the type of eyelashes you use, and the style you want.
