Everything You Need to Know About Eyelash Extension Glue

Eyelash extension glue is one of the most important products for lash technicians, directly affecting the durability and quality of the lash set. However, understanding the ingredients, shelf life, storage, and other factors will help you maintain the glue’s quality in its best condition. Let’s explore the details with LavisLash in this article!

Basic Ingredients Found in Eyelash Extension Glue

- Cyanoacrylate: This is the main ingredient in most eyelash extension glues, responsible for the fast and strong bonding. Cyanoacrylate reacts with moisture in the air to form a durable bond between natural and artificial lashes. Depending on the type of glue, the amount of cyanoacrylate may vary to suit different needs, from fast-drying formulas for professionals to slower-drying ones for beginners.

- Carbon Black: This ingredient gives the glue its black color, helping it blend perfectly with natural lashes, providing a more natural and defined look. Some glues do not contain carbon black (clear glue), which is designed for sensitive clients or colored lash extensions.

- Hydroquinone: Hydroquinone is used to prevent the glue from drying too quickly. Its advantage is that it remains in liquid form but hardens instantly upon exposure to air.

- Poly Methyl Methacrylate (PMMA): PMMA is the key ingredient that helps the extension adhere securely to the natural lashes. It is a lightweight acrylic glass that has adhesive properties. Generally, the higher the PMMA content in the glue, the longer the bond lasts. PMMA is highly durable and is also used in bone reconstruction.

Some ingredients in eyelash extension glue may cause allergic reactions in clients. Therefore, lash technicians should be cautious when selecting the right products and always provide thorough consultations with clients before applying eyelash extensions.

How Long is the Shelf Life of Eyelash Extension Glue?  

Eyelash extension glue typically has a short shelf life after being opened. Once the glue is exposed to moisture in the air, the humidity will start to cause it to harden. Therefore, it’s essential to store the glue properly, in a sealed container, in a cool, dark place, away from direct sunlight.  

Typically, unopened eyelash extension glue will last for about 2-3 months, and once opened, it should be used within 1 month. If the glue is not stored or sealed properly, it can dry out and lose its effectiveness. It may also release fumes and react with the surrounding moisture, potentially leaving behind cloudy residue.  

Additionally, you can check the expiration date on the bottom of the glue bottle to ensure that it is still effective and safe to use for eyelash extensions.

How to Store Eyelash Extension Glue  

Eyelash extension glue is sensitive to environmental factors, so proper storage is essential to maintain its high quality. Here are some important factors to keep in mind when storing your glue:

• Temperature  

- Eyelash extension glue should be stored in a cool place, ideally between 18-25°C.  

- Avoid direct exposure to sunlight or high heat sources, as excessive heat can cause the glue to lose its bonding strength or clump.  

- In winter, if the temperature is too low, the glue may freeze, which can affect its performance. Lavislash provides guidelines on how to store glue during the cold winter months here.

• Humidity  

- The ideal humidity range for storing glue is 40-60%.  

- If the humidity is too low, the glue can dry out faster, making it more difficult to work with. On the other hand, if the humidity is too high, the glue could become thick or lose its bonding ability.  

- To control the humidity, store the glue in a moisture-proof bag or airtight container with a silica gel pack to maintain a stable environment.

• Placement of the Glue 

- After use, always close the cap tightly to prevent air and moisture from getting in.  

- The glue should be stored in an upright position to prevent leakage or clumping around the mouth of the bottle, which can make it difficult to use the glue in the future.  

- Avoid placing the glue near heat sources, air conditioners, or in the refrigerator, as sudden temperature changes can affect the glue's quality.

• Additional Storage Tips

- If you don’t use the glue frequently, store the bottle in a sealed bag (with a silica pack) and place it in an airtight box to maintain a stable environment.  

- Note the date when you first open the glue to keep track of its shelf life and avoid using expired products.

Conclusion 

Using eyelash extension glue correctly not only improves the quality of the lashes but also ensures the safety of your clients. Pay attention to storage, expiration dates, and replacing the glue at the right time to always provide the best experience.
