    There’s nothing worse having your eyelashes fall off in the middle of the day because your glue didn’t last long enough. Or getting red eyes because the glue you thought was hypoallergenic wasn’t. If these describe some of the issues you’ve been having and you’re in need of glue that actually works, check out our DUO Eyelash Glue Review below. 

    World’s best-selling invisible adhesive for fake eyelash’s

    DUO Brush-on Strip Lash Adhesive is the world’s best-selling invisible adhesive for fake eyelash’s. DUO claims that their eyelash glue is hypoallergenic, economical, and will last you all day and night. 

    Not only did this glue last all day and all night, we didn’t need to reapply the glue (minus a few touchups here and there) for nearly two weeks, which is incredible. 

    But does it hold up? Let’s find out.

    Duration of Hold

    Does this duo lash glue really hold out all day and all night? That’s what the company claims, and from our experience, that’s also what they deliver.

    Is DUO Eyelash Glue Waterproof or Not?

    DUO claims that this glue is water resistant and will hold up against just about any wetness. Watering eyes, showering, crying, etc., you should have nothing to worry about. 

    During our testing we had plenty of opportunities to get our fake lashes wet. A few of us watched movie that made us cry while others left the lashes on in the shower. Some of us also get pretty bad allergies and are always dealing with sinus issues and runny eyes, and still we had no problem.

    In fact, it’s highly possible that the glue on the fake lashes held up longer than our mascara. 

    Even with all that said, we wouldn’t recommend pushing the envelope. Don’t spend an in ordinate amount of time submerging your face in water. After all, we’re not mermaids. Spend enough time in water, especially warm salty water or pool water filled with chemicals, eventually the bond that holds the lashes to your skin is going to give way. 

    That doesn’t mean the glue is faulty. It’s just science working it’s magic.

    Along with the DUO Brush-on Strip Lash Adhesive, we tested two other lash adhesive products to see how they stood up to each other in terms of hold duration. The first product we tested was the Cardani Latex-Free Secure Glue for False Eyelashes.

    The Cardani lash glue really impressed it. Not only is it half the price of the DUO brush-on, which is already pretty inexpensive, but it performed just as well. Both glues brush on, so application is super easy, and both are hypoallergenic and latex-free, so no nasty rashes or allergic reactions.

    What really sets the Cardani brand above DUO is that it’s made cruelty free (not tested on animals), and the glue has a slight blue tint before drying, making it easy to see where you’re putting it.

    Spot Testing

    Before you use any eyelash glue for the first time, no matter how hypoallergenic they claim to be, it is strongly advisable to do a spot test first before applying fake lashes to your eyelids.

    Every person’s skin is different, and even a hypoallergenic and allergen free product can possibly make someone react differently than intended. 

    The best way to spot test the DUO brush on adhesive is to first find a small area on your skin, preferably your arms, and then just press the tip of the brush to that area. 

    Wait roughly 24-48 hours before trying the glue on your eyes. If the spot that you tested begins to show any signs of reacting, like redness, itching, or worse, do NOT use this glue near your eyes, and find a different lash glue to try.

    If there’s an adverse reaction, we recommend trying the Cardani lash glue we mentioned above. Another suggestion is the other product we tested, the Callas lash glue. Be sure to compare the ingredients in all three adhesives to make sure that the Cardani and Callas don’t have the same thing that the DUO did that made you react.  

    If, however, your skin doesn’t react to the DUO lash glue, then you’re free to go. Put those fake lashes on and bat your eyes as much as you want. They are not going to fall off, we promise.

    DUO Lash Glue Intended Application

    To be clear, the intended application of DUO eyelash adhesive is to be used to apply fake eyelashes to your eyelids.

    There are a few reasons women like to wear fake eyelashes. One, they can be super cool looking. Even if you’re normal eyelashes are fine, some false ones can have fun colors or sparkly glitter (or both!). 

    Another reason is not every woman is blessed with full eyelashes. Either they were born with sparse lash growth, or something changed as they got older and they suddenly lost lash volume. Wearing false lashes can really help a woman feel beautiful to herself and boost her self-esteem.

    And third, women who have lost their eyelashes either in a freak accident or to disease will want to wear false eyelashes. Whether it’s temporary until the lashes grow back, or a permanent deal, false eyelashes are a great way to boost a woman’s self-worth. Your falsies need the best eyelash glue available.

    Applying and Removing Your False Lashes

    Applying and removing your false lashes doesn’t have to feel like brain surgery, we promise. As long as you follow instructions, it is super quick and easy, and in seconds you’ll have the lashes you’ve always wanted. 

    Steps for applying your false lashes:

    • Don’t forget to do your spot test like we discussed above. If your skin did not react, go ahead and carry on to the next step.

    • DO NOT put the adhesive directly on your eyelid. This will result in using far too much adhesive, and could risk getting into your eyes and causing irritation or an infection. 

    • Take the tip of your brush in one hand and the fake lash in the other, and use the tip of the brush to apply the adhesive directly to the bottom of the eyelash, from end to end. Remember, you don’t need globs of glue, you only need a very thin layer. 

    • Don’t immediately put the lash on your eyelid. Count out 30 seconds, then begin fitting the eyelash to your eyelid. Use tweezers if you need to for greater control. 

    • Press the lash strip gently against your eyelid for about 10-15 seconds to make sure the glue holds strong.

    Taking the lashes off can be a little trickier, especially if you’ve used a glue like DUO that holds on strong. Some women will use makeup removers to help, or baby oil to release the glue, while others will simply pull the lashes off their skin. 

    The best thing to do is be gentle, and go slow. If you have a makeup remover you like, put some on a Q-tip and use that to gently release the glue and pull away the lash. If you have baby oil instead, do the same thing.

    We mentioned above that we tested two other lash glues, the Cardani lash glue, and the Callas Eyelash Adhesive Clear (Latex Free). All three glues held up well during the waterproof testing, but the Cardani was the only one still holding on super strong when we went to remove the lashes.


    DUO brush on lash glue is a great product to try if you’re having issues with the glue you’re currently using. It’s cheap, easy to put on, and will last you many days and nights. It's still worth checking out our Kiss Eyelash Glue Review.
