BL Lashes Crystal Drop | Lash Sealant for Long-Lasting Lash Extensions Retention, Waterproof Coating, Brush Type Lash Sealer (0.24 fl.oz, Clear)

I was skeptical about this at first, but it actually made my lash extensions last much longer than expected. Super easy, I use it like a mascara once in the morning and again before bed, and I bought it over a month ago but I’m probably only about 1/4 of the way through the bottle, so it’s lasting me a long time. Even using it before a shower hasn’t irritated my eyes. It’s lightweight, doesn’t leave behind a lot of buildup or goop or take long to dry, and doesn’t feel harsh or cause my lashes to clump. I’m really impressed with how well it works. Happy with it!

My only complaint is wishing I knew about this stuff sooner. I had been having to get my lash extensions done every week, because they’d fall out. I go to the gym just about every day, so sauna just about every day. Lots of sweat happening! I also only wash my hair about every 4-5 days so there is some oil buildup. I started using this stuff and my extensions are going strong after a week now! I do have a system though. Make sure lashes are dry before applying -I reapply every time I wash my lashes. This stuff is waterproof but does wash out. Found out through trial and error -when you apply, make sure lashes are completely dry and combed through. I run the sealer wand over my lashes from base to tip, then comb them out from underneath, ensures they’re all coated. Then run a dry spooley through them again and comb them out. -If I need to reapply and I haven’t washed my lashes directly before yet, I put some witch hazel on a spooley and comb my lashes out to get rid of any oils. Let dry. Then apply the sealer. Comb them out. -I always make sure they are coated before gym and sauna. I shower at night and hit the gym in the morning, so they are good and ready to go. -after my sauna time, I wash my hands and run water through my lashes real quick to get rid of any sweat. So far, this has been working really well! Which I was shocked for the price of this stuff. I researched other products, and liked that this one doesn’t makes lashes stiff. I saw some reviews saying it did, but I think that’s because people are applying more than one coat in between washes.

I've been getting lash extensions for a few months now and I would only get about a week out of them by the second week when I was due for a lash fill they were almost gone and I did all of the things I'm supposed to do. Then I discovered this product. I barely lost any Lashes in the two weeks after my lash fill. I'm so excited I found something that works and gives me longevity with my extensions. This pic is one day before my lash appointment (two weeks since my last one)

It’s okay, it does feel nice when brushing through my extensions and helps get rid of some of the stickiness and tackiness. I’m still on the hunt for the perfect lash coat/seal and this one’s not that bad but I will probably be trying other ones after this.

I really love the sealant and I feel it definitely helps with retention of my lashes. It does not leave any white residue. I wash my lashes and the brush them out and then when they are fully dry I apply the lash sealant and then brush them out again. After they dry they look so much cleaner and it helps to keep the dirt and oils from building up on your lashes so they don't fall out as easily/fast. If you use too much or don't brush your lashes out after you apply the sealant, it can make your lashes feel crunchy. Can be used for day or night but I usually apply it at night. A little goes a long way and even though the bottle isn't very big, it lasts a long time! I've accidentally gotten a little in my eye and it didn't really sting that bad but it could be worse for someone with sensitive eyes.

I’ve been using this for about a month now, primarily to see if I could stretch the time between my lash fills. Here’s the breakdown: while the sealer is actually on, I notice significantly less shedding. However, the moment I wash and comb them out, the lashes fall at their usual rate. It seems the sealer doesn't necessarily stop the natural shedding process; it just holds the loose lashes in place until they're cleaned.

Good product for the price point. Having lash extensions, it's a must to have a sealant. I've used ones without a spoolie intended and much thicker that left visible clumps of product behind. I do use it every other day and it does the job it says. Is difficult to know how much you're putting on, but your lashes will feel wet. Very much like it comes with a spoolie for easier application for myself. 11.14.25 update - my lash teach said I had better retention than before. Switched from one I used before to this and because it's easier to apply, it's easier to get to more of my lashes. Rating will go up to a 5 star from the original 4 because the product does work fully as intended.

I gave this product a chance despite the mixed reviews. I regret it. Furthermore, I had my fill-in done only 8 days ago. I already have fairly decent retention of 3 weeks. However, I wanted to see if this product would extend my retention to 4-5 weeks. Within hours of putting this product on my lashes, I had about a dozen lashes fall off in the shower and just by a light touch of my fingers. My lashes have never lost that many in such a short span of time, even in the shower! I usually lost about 1-2 lashes per day, not almost a dozen. It seems like this product breaks down the glue, which I should have realized with the first ingredient and most prevelant being ALCOHOL. Alcohol typically breaks down adhesive. I don't know why I thought this would be some magic formula. I am returning it right away after using it ONLY ONCE. Be careful of these cheap, knock products on Amazon

I was dubious to try this but I usually need infill after a week using this I have passed 2 weeks without needing infill. Highly recommend this product
