Mach Glue

Mach Glue

Introducing the Advanced Formula Mach Glue, tailored for proficient lash artists with fast application skills, offering an impressive 1-second setting time.

It's important to note that the fast-setting nature of this adhesive can present challenges if the extension attachment process is prolonged. The glue may start to partially dry before successfully attaching the extension to the natural lash, potentially leading to shorter retention times.

For this reason, we highly recommend that this adhesive be reserved for use by expert lash technicians to ensure optimal results. This Mach eyelash extension glue is perfect for those seeking increased revenue from short application time. 

To use the lash extension glue for a long time, pay attention to the precautions and storage methods.

1. When discharging the glue, lift the outlet from the surface slightly as the dust or dirt may be sucked into the container.
2. Wipe the glue nozzle with a piece of paper immediately after use.
3. Close the lid tightly and seal it instead of just placing a lid on it to prevent contact with moisture.
4. As it was manufactured, store the glue in a sealed zip-lock bag with the desiccant.
5. Store it in a dry and cool place, avoiding direct sunlight.
6. In humid seasons or environments, you can purchase extra desiccants in the glue zip-lock bag. By doing so, you can prolong the expiration date.

Expiry & Usage Duration:

•For 10g Glue: 6 months before opening and 1 month after opening the glue bottle.
•For 5g Glue: 5 months before opening and 1 month after opening the glue bottle.
•For 3g & sensitive Glue: 3 months before opening and 1 month after opening the glue bottle.


How to store

1. Store it in a dry and cool place, keep it away from direct sunlight.
2. Proper storage temperature: 3°C to 25°C before opening and 15°C to 25°C after opening the bottle.
3. Proper storage humidity: The Lower the humidity, the fresher the glue can be stored.
4. Do not refrigerate the product as condensation will adversely affect the performance of the product. (If the storage environment temperature of the product is too high, refrigerate the unopened product, take it out 2-3 hours before use, and use it at room temperature.)

1. Optimize Room Conditions: Adjust the room's humidity (45-70%) and temperature (22~26 degrees Celsius) to meet the recommended levels.
2. Properly Clean Natural Lashes: Ensure a thorough cleaning of natural lashes by using Lash Shampoo to eliminate dust, oils, and makeup. Rinse thoroughly before applying lash extensions. After cleansing, prepare natural lashes by using a lash primer to hydrate and neutralize the PH level.
3. Check Eyelash Glue Freshness: Examine the freshness of your professional eyelash glue bottle.
4. Use Fresh Glue Drops: Squeeze out fresh glue every 20 minutes, and consider shorter glue replacement cycles, especially in high humidity environments, as the lash glue tends to harden more quickly in such conditions.
5. Apply Adequate Glue: Always ensure to apply a sufficient amount of glue. Too little or a very thin layer may not provide enough adhesion to hold the extension in place over the next few weeks.
6. Check Correct Attachment: Verify that the attachment is correct, with at least a 2mm attachment to the natural lash.
7. Avoid Layering Glue Drops: Avoid applying fresh glue directly onto the previous drop of glue, as it may result in a viscous texture and compromise the adhesive bond’s quality.
