  • Eyelash glue can expire within 3 – 6 months, even if unopened.
  • Proper storage conditions and the type of lash glue can affect its shelf life.
  • Expired eyelash glue can lead to infections and poor adhesion, so it’s important to replace it when necessary.
  • Other lash supplies like under-eye gel pads, lash primer, mascara, and eyeliner also have expiration dates that should be monitored.

How Long Does Eyelash Glue Last?

Eyelash glue typically lasts for about six months to one year, depending on various factors such as storage conditions and frequency of use.

4 Factors that Affect Shelf-Life

Proper storage is significantly influential in maintaining the shelf-life of eyelash glue. The environment should be cool and dry, away from direct sunlight as heat can cause the adhesive to break down quicker. This could lead to earlier expiration even when unopened.

Moreover, the brand and type of lash glue play a vital role in determining its lifespan too. Certain glues expire between three to six months whether it’s sealed or not, while others like DUO Lash Glue can last up to half a year given that they remain unopened.

Furthermore, the manufacturing date serves as an essential factor for your eyelash glue’s freshness hence it should always be checked upon purchase.

When to Replace Your Lash Glue

Eyelash glue should be replaced in specific circumstances to ensure the safety and effectiveness of your lash extensions. One important factor to consider is the shelf life of the adhesive.

If you have opened the lash glue, it typically has a shelf life of around 1 month. However, even if unopened, eyelash extension glue can expire within 3-6 months. Another sign that it’s time for a replacement is if the adhesive starts to deteriorate chemically or becomes clumpy and thick in consistency.

Using expired lash glue can lead to infections around your eyes due to bacterial and fungal growth, resulting in swelling, redness, and discomfort. To determine whether your lash glue is still fresh and effective, always check its manufacture date before use.

The Shelf-Life of Other Lash Supplies

Other lash supplies such as eyelash extensions, under-eye gel pads, lash primer, eyelash extension glue remover, lash extension sealer, makeup remover & lash cleanser, lash growth serums, and mascara and eyeliner also have their own shelf-life that should be monitored.

Eyelash Extensions

Eyelash extensions are a popular beauty trend that can enhance your natural lashes for a more dramatic look. When getting eyelash extensions, it’s important to consider the quality of the lash glue being used.

Just like regular eyelash glue, lash extension glue also has an expiration date. The shelf life of eyelash extension glue can vary depending on the brand and type, but generally, it should be used within 3-6 months if unopened.

Once opened, the shelf life decreases to about 1 month. Using expired lash extension glue may not only result in poor adhesion and shorter-lasting lashes but also increases the risk of bacterial and fungal infections around the eyes.

Under-Eye Gel Pads

Under-eye gel pads are a must-have for anyone who loves wearing eyelash extensions. These small patches provide comfort, protect your lower lashes, and help keep your skin smooth during the application process.

It’s important to note that under-eye gel pads also have an expiration date. While it may vary depending on the brand, most gel pads have a shelf life of about 6-12 months from the date of manufacture.

Using expired gel pads can lead to irritation and discomfort, so make sure to check the expiration date before using them.

Lash Primer

A lash primer is a crucial step in your eyelash extension routine. It helps to prepare your natural lashes for the adhesive, ensuring better adhesion and longer-lasting results. Most lash primers contain nourishing ingredients that strengthen and condition your lashes, promoting healthy growth.

By applying a thin layer of primer before attaching the extensions, you create an ideal surface for the glue to bond with, resulting in a more secure and seamless application. Using a lash primer not only improves the longevity of your extensions but also enhances their overall appearance by adding volume and thickness to your natural lashes.

To use a lash primer effectively, make sure to apply it sparingly from root to tip using either a brush or wand applicator. Allow it to dry completely before proceeding with the rest of your lash application process.

Remember, using expired or old lash primers can affect their effectiveness and potentially compromise the quality of your extensions. So be sure to check the expiration date on the packaging before using any product on your lashes.

Eyelash Extension Glue Remover

Expired eyelash extension glue remover should never be used. Just like other lash supplies, eyelash extension glue remover has a shelf life and can deteriorate over time. Using expired remover can potentially damage your natural lashes and cause irritation or allergic reactions.

Always check the expiration date on the bottle and discard any old or expired glue removers to ensure safe and effective use.

Lash Extension Sealer

Using a lash extension sealer can help prolong the life of your eyelash extensions. This product forms a protective barrier that seals in the adhesive, providing extra security and preventing premature shedding.

It also helps to maintain the shape and curl of your lashes, keeping them looking fresh and beautiful for longer. Applying a lash extension sealer regularly can extend the lifespan of your lash extensions, saving you time and money on frequent touch-ups or replacements.

Make sure to choose a high-quality sealer that is compatible with your adhesive for best results.

Makeup Remover & Lash Cleanser

Makeup remover and lash cleanser play an essential role in maintaining the health and longevity of your eyelashes. These products help remove dirt, oil, and makeup residue that can build up on your lashes throughout the day.

By gently cleansing your lashes, you can prevent potential infections and irritation. It is crucial to choose a gentle formula specifically designed for use around the eyes to avoid any discomfort or damage.

Regularly incorporating a makeup remover and lash cleanser into your beauty routine will keep your lashes clean, healthy, and ready for their next fabulous look.

Lash Growth Serums

Lash growth serums are popular products that can help enhance the length and thickness of your natural lashes. These serums are designed to stimulate lash follicle growth, making your lashes appear longer and fuller over time.

Using active ingredients like peptides and vitamins, lash growth serums nourish the lashes from root to tip, promoting healthier and stronger lash growth.

When choosing a lash growth serum, it’s important to consider the expiration date. Just like any other beauty product, lash growth serums also have a shelf life. It is recommended to check the expiration date before using them on your lashes for optimal results.

Mascara and Eyeliner

Expired mascara and eyeliner can pose risks to your eye health. Just like other beauty products, these items have a shelf life. Expired mascara can become dry and clumpy, making it difficult to apply smoothly and increasing the risk of flaking into your eyes.

Old eyeliner may lose its pigment or consistency, leading to smudging or irritation on the delicate skin around your eyes. Using expired mascara or eyeliner can also increase the chances of eye infections due to the presence of bacteria or fungi in the product.

To ensure safe usage, it’s important to regularly check the expiration dates on your mascara and eyeliner tubes and replace them when they’re past their prime.

Why You Should Not Use Expired Lash Supplies

Expired lash supplies, including eyelash glue, should never be used for several important reasons. Using expired lash supplies can lead to bacterial and fungal infections around the eyes, which can cause uncomfortable symptoms such as swelling, redness, and pain.

Expired eyelash glue may not adhere properly and may not last as long, compromising the effectiveness of your eyelash extensions. It is crucial to check the manufacture date of eyelash glue to ensure its freshness and safety.

To prioritize your eye health and maintain beautiful lashes, it is best to discard expired lash supplies and use fresh products that are within their recommended shelf life.

How to Properly Store and Keep Track of Your Lash Supplies

To ensure the longevity and effectiveness of your lash supplies, it is essential to store them properly and keep track of their expiration dates. To begin with, make sure to store unopened eyelash glue in a cool and dry place.

Avoid exposing it to extreme temperatures or direct sunlight, as this can accelerate the expiration process. Additionally, be diligent about checking the manufacture date before purchasing any lash supplies so you know exactly how fresh they are.

When it comes to opened eyelash glue, remember that it generally has a shelf life of only one month. To prevent it from drying out or losing its effectiveness, always tightly seal the container after each use.

You can even extend its lifespan by using a Sharpie marker to write the opening date directly on the bottle.

To keep track of your lash supplies’ expiration dates more easily, consider creating a system that works for you. Whether it’s setting reminders on your phone or keeping a printed chart near your beauty station, staying organized will help ensure that you’re using fresh and safe products on your lashes.


It is crucial to keep track of the expiration dates of your eyelash glue and other lash supplies. Using expired eyelash glue can lead to infections and poor adhesion, compromising the safety and effectiveness of your lashes.

By properly storing your adhesive and replacing it when necessary, you can ensure a flawless lash application every time.
