Does Eyelash Glue Expire? If Yes, When?

A frequently asked question is “Does eyelash glue expire?” Well, it does (just like every other product), and you’d better purchase an appropriate amount of eyelash glue, along with a few extra as backups, to ensure long-lasting, and effective results. Eyelash glue that has passed its expiration date may result in poor lash retention, one of the least desirable outcomes. The main ingredient in a lash glue, Cyanoacrylates does have a long shelf life as long as it is stored correctly, and used according to instructions. When unopened or stored properly, your lash glue can last up to 3 to 6 months from the manufacturing date. But once it is opened, its lifespan will become shorter. This will be dug deep to a greater extent in the sections below.

When using lash glue on any of your clients, it’s more ideal to be utilized within four weeks of opening. This ensures optimal performance and reduces the risk of poor lash retention, or all those adverse reactions. It is important to follow the manufacturer’s guidelines and check the expiration date to ensure the adhesive is still within its usable period.

There are certain indications that suggest the need for replacing lash glue. These include the separation of black carbon pigment, revealing clear adhesive, the lash glue getting clumpy or excessively runny; and the glue remaining tacky even after a good shaking for minutes. If the glue has dried out and cannot be dispensed from the bottle, it should be replaced. Should any of these signs be observed with your lash glue, just discard the old and acquire a new one. Prioritize client safety and satisfaction by avoiding using expired products that may lead to subpar lash retention or dissatisfied the clients. Moreover, expired lash glue may also increase the risk of any adverse reaction. If the ultimate goal is to please your clients, always  make sure to offer them reliable and fresh lash glue.

Factors For How Long Does Lash Glue Last

1. The Manufacturing Date Of The Glue

The first factor to consider when assessing the freshness of a lash glue is the manufacturing date. This date holds significant importance as it shows the initial exposure of the glue to air, which initiates its deterioration process. Lash extension glue tends to release a specific type of gas once it is formulated. If this builds up and expands within an airtight bottle, it can cause the bottle to explode. Hence, it’s crucial to store lash glue in a bottle that allows for proper airflow. PE, a breathable plastic, is considered the most suitable material for lash glue that facilitates minimal airflow and prevents the glue bottle from exploding. When kept in optimal conditions, unopened adhesive can maintain its best quality for a maximum of 6 months. Many lash brands don’t directly indicate the manufacturing or expiration date on that product packaging. Instead, they typically include a batch code or lot number, which is printed on the container bottom or product packaging.

2. The Date When The Glue Is First Opened

The second factor to consider is the duration after opening the lash glue for the first time. If a product is exposed to air, its quality begins to deteriorate at a faster rate. Once opened, lash glue will expire within approximately a month, with the sensitive one, which expires slower (5 weeks to 3 months) compared to the regular eyelash glue. It is vital to keep track of the date when you initially open the product. One effective way is to use a sharpie to clearly mark the opened date on the back of the package. Also, maintaining the appropriate temperature and humidity levels in the storage area, along with paying close attention to proper storage methods, can help prolong the expiration date of the lash glue.

What Will Happen If I Use Expired Eyelash Glue?

There are several signs that indicate lash glue has expired. If you notice any of these signs it is best to discard the glue and replace it with fresh and unexpired products to ensure optimal results and safety to your natural eyelashes.

Expired lash glue may become thicker, clumpy, or stringy in texture. It also loses its adhesive properties and fails to create a strong bond. The color of the lash glue may change over time becoming darker or exhibiting other discoloration when expired. If your lash glue emits a foul or unusual smell, it could be an indication of expiration.

Expired lash glue may not provide the desired lash retention or longevity. Lashes may start to fall off sooner than expected or not adhere properly, as well. Using old or expired lash glue is fiercely discouraged and must never be done. The potential risks and negative consequences outweigh any benefits. When lash glue is outdated, it may lead to poor lash retention that causes the extensions to fall out prematurely. Your eyes also are more susceptible to adverse reactions when exposed to any expired product ingredients.

To ensure optimal safety and quality, it is vital to always use those fresh and within-date lash glues on your natural eyelashes. The presence of bacteria and fungus underneath the lash glue can result in infections, which lead to symptoms such as swelling, redness, and significant discomfort in the eye area. Also, the lashes themselves can potentially cause irritation to the cornea. Furthermore, as the glue thickens, it may detach and potentially scratch the cornea, posing further risks/complications.

How To Get Lash Glue The Longest Shelf Life?

Lash glue can be temperamental but with proper care, it is likely to extend its lifespan just by storing opened adhesive in a cool, dry place and ensuring to shake it before each use which can increase its longevity to around 6 months. The method of applying the adhesive is much easier when it is fresh. Your eyelash glue’s effectiveness may be sustained for up to 30 days by following the instructions below!

  • Burp the lash glue bottle: Air exposure can cause lash glue to dry out and expire faster. So regularly burping the bottle will help remove air and keep it out. Only the glue remains in the nozzle after you squeezed the bottle till a bubble emerges from the top. Shake and replace the cap after giving the lash glue bottle a good burp before adding another drop.
  • Keep your distance from natural fibers: Eyelash glue reacts with natural fibers, most commonly, cotton or paper. To clean the nozzle, avoid using cotton products. And to maintain it clean without facing the risk of irritation on your skin, use lint-free glue nozzle wipes. Also, prevent the glue from touching clothing, as it can cause permanent damage.
  • Shake up your lash glue: Always shake the lash glue before any use. Similar to foundation bottles, the ingredients can separate so shaking ensures proper consistency. Insufficient shaking is indicated if your lash glue becomes clear or partially transparent.
  • Shake it as much as possible: Your lash glue can last longer if you shake it every day. Glue shaking equipment is available, however it may also be done by hand. Shake the glue bottle horizontally for 2 minutes at the start of the day, and shake it again for about 15 to 20 seconds before applying a new drop.
  • Never shake with the cap on: Always avoid shaking the glue bottle with the cap on as it can cause the lid to become stuck. This can be frustrating and wasteful, so just have a backup bottle of eyelash glue in case this happens. Use a pin or tool provided with your glue to clear the nozzle when shaking it along.

In What Way Should I Store My Eyelash Glue?

Proper storage of lash glue involves ensuring itself is securely closed and positioned upright. Once opened, it should be stored in a cool and dry environment, ideally at a temperature of around 19 degrees Celsius. Also, transferring the adhesive to an airtight container designed for lash glue can help maintain its freshness for a longer period. It is needed to avoid storing lash glue in refrigerators or freezers, as this might lead to the accumulation of condensation, ultimately reducing its shelf life to less than two weeks.

When Is It Ideal To Replace My Eyelash Glue?

As for the frequency of changing lash glue, it is suggested to replace the glue drop every 15 to 20 minutes, while performing the lashing procedures. This is because exposure to air and the humidity of the room can alter your glue’s consistency, making it difficult to work with and less effective. By changing the glue drop within this timeframe, you’ll soon be able to ensure optimal performance and maintain the desired lash outcomes.
