this product works but problem is you need to keep repurchasing and keep using this. one problem is that its around the 10-15 dollar range and if you have to buy this constantly every few months it might start to feel a little pricey. also i dont like how after awhile when it dries it starts having these funny flakey things on my lashes and that does not look nice when youre out and you didnt check the mirror :(!

I've used this product on and off over the past year. I feel the greatest change is usually seen in the first 2 weeks of using it continously. I think what it basically does is prevent you eye lashes from falling out for a little bit longer, making them seem thicker. That's why usually when I stop using it for long periods of time my eyelashes look slightly thin again.Overall though for the price, the outcome is pretty good. I have continued to use it cause I still love the effect it gives me eyes. I can go without mascara and still know that my eyes stand out!

I'm telling you guys, it works. The first two weeks, I applied it twice a day. Then it was once a day and now, once a day and I skip 1 or 2 applications... That's why my container is not empty! Oh, and serum on the lower lashes is not recommended (as mentioned on the packaging).

What do I think? lengthening, yes, but volumizing no. Also, when dry, the product leaves a whitish deposit. Personally, I do not wear mascara when my eyelashes are coated with the serum because they become textured (like hair covered with a styling product) and they clump, so it gets quite difficult to separate them with the brush.

I already have fairly long eyelashes but heck what girl doesn't want longer and fuller eyelashes? So I had to give this product a try. I am in LOOOOVE! I started noticing result during the second week of use. My eyelashes are a lot thicker than they were before. I just have to remember to use it twice a day. I put it along my lash line at night and under my mascara during the day. I have recommended this to so many of my friends and they have all been happy with the result...

I can't say enough about this product. It really does work. I apply the serum and right away my lashes look thicker and darker. They even curl up at the ends. It's a great enhancer for a very natural, every day look. For evenings, I apply the serum and then mascara and WOW!! My lashes pop! Would definitely recommend this product.

It works! It takes a little while but after two weeks of consistent use before bed I'm noticing that my lashes DO appear longer! They are also thicker and darker :D Will definitely continue using it and buy again!

This tiny tube of stuff works wonders! I've got the most invisible eyelashes that would fall easily when I used to curl them. When I started this little regime every night and after 3-4 weeks, my eye lashes where surprising longer, thicker, stronger, and amazingly visible. I've gotta hand it to L'oreal, they're pretty smart and good on the price.

I’ve read a lot of good reviews about this product so I had to try it out.
Unfortunately I’m not as happy with it. I have fairly good and long lashes already, so maybe that is why I didn’t see a difference.
I found the application a bit difficult. Due to the shape of the applicator it was hard to get the product all over the lashes and when it came to the root application I had trouble again getting the product in all the right places, without getting some in my eye. Aside from that, like I mentioned before, I didn’t see any improvement in the length or strength of the lashes. I am not sure if it takes more than one tube to actually see results, maybe I’ll try it.
For now, I’m going back to my old lash treatment, which works beautifully: castor oil vit E oil.

I have very thin, short, barely-there lashes, which is why I picked out this product. I used it every night before going to bed; you can also put some on in the mornings before you put on mascara, but I didn't. Applying the serum is easy, just use the curved applicator like you would mascara and trace some along your lashlines as well. I even put some on my bottom lashes even though the directions said not to...hehe! Your lashes will feel wet until it dries, but if you get some in your eyes (which I did often), it does not sting/hurt at all and had no adverse reactions to my eye. However, when it dries, it leaves little white flakes on your eyelashes (which are easily covered with mascara).

I saw results after about four weeks, my eyelashes did not get much longer, but I seemed to have a lot more lashes and each individual lash was thicker! The results are subtle but definitely there. I have been using this product almost every night for about there months and there's still a lot of serum in the tube.

I've been using L'Oreal Double Extend Lash Boosting Serum for about 10 weeks and it has strengthened my lashes so that they are able to grow longer. I saw some thickness but the results were not as drastic as length. I was supposed to use this morning and night for at least 4 weeks to see results, but I only used it at night and about 5-7 times a week and still saw results! I would recommend this to anyone looking to lengthen their eyelashes but if you are looking for thicker lashes, this will only help a little.
