How to use
To achieve the best retention with MARY LASH m4 adhesive, follow these guidelines:
Best Temperature for M4 Adhesive: 14-27°C (57-81°F) with humidity levels of 30-80%.
Temperature and Humidity Considerations:
- If the temperature is below 18°C (64°F), the adhesive may dry slower.
- If the temperature exceeds 22°C (72°F), the adhesive may dry faster.
- Low humidity (below 50%) can slow down adhesive drying.
- High humidity (above 65%) can accelerate adhesive drying.
Optimal Working Conditions: Working in ideal conditions for the adhesive ensures proper drying time, leading to excellent lash retention. Use a hygrometer to monitor the conditions in your workspace.
Temperature Control Tips:
- Use an air conditioner, fan, heater, or radiator to adjust the temperature in your lash room.
- Use a humidifier or dehumidifier to adjust humidity levels as needed.
Effects of Improper Handling: Incorrect use of fast-drying adhesive can result in poor lash retention. High humidity and temperature can cause the adhesive to dry too quickly, potentially leading to lash fallout within a few days after the procedure.
Storage and Handling Tips:
- The shelf life of m4 adhesive is 9 months from the manufacturing date before opening. After opening, replace the adhesive bottle every four weeks for optimal performance, with a maximum usage time of 2 months if opened frequently.
- Store the adhesive upright in a dry place away from direct sunlight, ideally in a sealed container.
- To track adhesive freshness, label the bottle with the date of opening.
- Use a glue mixer to ensure consistency in adhesive texture and remember to wipe the nozzle after each use to prevent clogging.
If you notice that your lash retention isn't ideal, follow this checklist:
Verify the humidity and/or temperature levels in the room are within recommended ranges.
Use lash foam to thoroughly cleanse the eye area from makeup. After thorough cleansing and applying eye patches, prep natural lashes using a degreaser.
If the adhesive works slowly, apply MARY LASH Primer to the lash strip. If the speed is insufficient, apply a booster to make the adhesive work faster.
Ensure you always work with a fresh adhesive drop (recommend changing adhesive drop every 10-30 minutes, or even more frequently in hot months).
Make sure you've taken a sufficient amount of adhesive. Too small a drop or a very thin layer of adhesive may not be enough to hold lashes on natural lashes for several weeks.
Verify your bonding is correct (at least 2 mm bond with the natural lash, no split or cross bases).
The adhesive drop used should neither be too large (more surface area means more adhesive exposed to air) nor too small (the adhesive drop will dry too quickly).
Do not add fresh adhesive to the previous adhesive drop (contact between "old" and "new" drops will make the adhesive very sticky).
If none of the above points work, consider switching to an adhesive with slightly slower drying time (e.g., m3) or consider enrolling in training at MARY ACADEMY.

m4 is my top favorite glue! It works great in any weather and is fast if you're experienced. The consistency is perfect—it thickens in higher humidity and works flawlessly. In low humidity, I use a booster (also from MARY LASH) to speed it up. Highly recommend!

Frequently Asked Questions
Below you will find some common questions asked by our customers about GLUE.
REASONS FOR POOR LASH RETENTION:
Glue speed- the glue worked too fast or the glue itself was too fast. Therefore, you just couldn't keep up with the glue, but the performance of your glue might have been accelerated by improperly used products or mistakes in the sequence of work.
Solution:Use a slower glue (for example, M1).
1. DO NOT use primer/booster on natural lashes and on the lash strip. If you have already used it, switch to the other eye or use lashes from the other side of the strip where there is no product.
3. Clean the lashes with products that have a neutral pH (MARY LASH degreaser, foam, saline solution).
4. In your work, first isolate the natural lash with straight tweezers, and only then dip the artificial lash in the glue.
5. It is important to place the lash correctly on the first attempt, you should not place it on the natural lash multiple times.
6. Drop a new droplet of glue - preferably in a glue ring - as the glue thickens more slowly in it.
GENERAL RULES THAT ALWAYS APPLY
1. Change Glue Regularly:
- Replace glue every 3-4 weeks, even if some remains. If you open the bottle only 1-2 times a week, you can stretch it to 2 months.
2. Monitor Room Humidity and Temperature:
- Always keep an eye on the humidity and temperature levels in your workspace.
3. Ventilate the Room:
- Ensure to ventilate the room before each client session.
4. Properly Clean Natural Lashes:
- Use a lash foam cleanser to clean natural lashes and the surrounding eye area from makeup.
5. Apply Neutral pH Degreaser:
- After thorough cleaning and applying patches, use a neutral pH degreaser on natural lashes.
6. Refresh Glue Drops Regularly:
- Change the glue drop at the first sign that something feels off (every 10-30 minutes).
7. Mix Glue Thoroughly:
- Mix the glue well for 30 seconds before dispensing a fresh drop, or use a glue shaker.
8. Avoid Mixing Old and New Glue:
- Do not add fresh glue to an old drop. Contact between the "old" and "new" drops will make the glue become sticky quickly. Discard the old drop before adding a new one.
9. Do Not Wipe the Lash with Glue on the Patch:
- The amount of glue should be adjusted by the speed at which you pull the lash from the glue drop.
10. Store Glue Properly:
- Keep the glue in a thermal bag and in a cool, dark place.
11. Keep the Glue Nozzle Clean:
- Always keep the glue bottle nozzle clean.
12. Wipe the Glue Nozzle Each Time:
- Clean the nozzle every time you use it.
13. Replace Nozzle and Cap Together:
- Change the nozzle along with the cap.
14. Hold the Tube Vertically:
- Keep the tube vertical when dispensing a drop.
15. Close the Glue Tightly:
- Ensure the glue is tightly sealed for proper storage.
GLUE WORKS SLOWLY:
REMEMBER - it is much easier to speed up the glue than to slow it down! So, it is not as bad as it might seem.
1. To speed it up, apply primer to the lash strip. If that is not enough, apply a booster to the lash strip. If it still doesn’t help, apply the booster to the natural lashes in the area without artificial lashes. Refresh the products every 30 minutes.
2. Check your work sequence - in such a case, it is important to first dip the artificial lash in the glue, and only then isolate the natural lash with straight tweezers and place the artificial lash on it.
3. Too much glue - this is a very rare case. Remember, the amount of glue depends on the thickness of the natural lash.
4. Very fresh glue - glue just after opening always works slower because it is very fresh and contains a lot of stabilizers.
5. Drop a new droplet of glue - a micro-droplet on tape works faster than in a glue ring.
6. If possible, increase the temperature and/or humidity in the room, and the glue will work faster.
7. If available, use a faster glue (for example, M4).
CHANGES IN GLUE BEHAVIOR DURING USE
The fresher the bottle, the slower the glue works, and conversely, the longer it has been opened, the faster it works. The same applies to the texture: the fresher the glue, the more liquid it is, and when the glue has been open for a long time, it becomes thicker, which significantly affects its performance.
WHY IS THIS?
This is due to the amount of stabilizers in the glue. With each opening, the amount of stabilizers decreases, causing the glue to change its behavior even under the same conditions.
Solution:
- Consider the texture of the glue. If you prefer working with liquid glue, use smaller volumes and change the bottle when the texture starts to change.
- Conversely, if you cannot work with liquid glue, open the bottle, use it until the end, and opt for a larger volume.
- It is essential to adapt to the glue's behavior based on these changes. Use the tips above to adjust accordingly.
Reasons That Could Affect Glue Performance:
1. Changes in Temperature/Humidity:
- Higher temperature and humidity levels make the glue work faster, and lower levels slow it down. Refer to previous tips on how to handle these changes.
2. Oxygen Levels in the Air:
- If there is insufficient oxygen, the glue performs poorly, and the technician may not understand why. Ensure to ventilate the room properly.
3. Additional Scents:
- Perfumes (yours or the client's), air fresheners, the smell of lamination solutions, hair dye, and other strong odors can negatively affect glue performance.
4. Technician's Mood:
- Sometimes, everything seems to go wrong, and the glue doesn’t work well, making you want to give up. Remember, it's just one of those days. If possible, take a day off, treat yourself to something nice, or do something just for you, not for your family, clients, or friends, but for yourself. The technician's mood is very important. Keep a positive attitude and don't forget about self-care.
