Generally speaking: the shelf life of unopened grafting eyelash glue is usually about 6 months to 1 year if it is well sealed and properly stored (cool, dry, and avoid direct sunlight).
After opening, the performance of the glue may gradually decline due to contact with air. If it is stored in a suitable environment and used as soon as possible, it can usually be used for 1-3 months. However, if the storage environment is not good, such as high temperature, high humidity, etc., its service life may be greatly shortened, and it may even lose its good viscosity and effect within a few weeks.
Ways to extend the service life of grafting eyelash glue:
1. Proper storage: Store the glue in a cool, dry and temperature-appropriate place, avoid direct sunlight and high temperature environment. The temperature is best controlled between 18-25 degrees Celsius.
2. Good sealing: After each use, make sure the lid of the glue is tightened to prevent air from entering the bottle and affecting the performance of the glue.
3. Reduce exposure: Try to shorten the time the glue is exposed to the air when using it to avoid the glue from being exposed to too much air and deteriorating.
4. Clean the bottle mouth: Before and after use, if the glue gets on the bottle mouth, clean it up in time to prevent the glue from solidifying at the bottle mouth and affecting the sealing effect.
5. Avoid pollution: When using glue, do not let eyelashes, debris or other contaminants enter the bottle.
6. Regular inspection: Check the state of the glue regularly. If you find any abnormalities, such as discoloration, thickening, odor, etc., you should stop using it.
7. Control the frequency of use: If you do not frequently perform eyelash grafting operations, try to reduce the number of times the glue is opened.
