I have been using smart lash for 4 months now with no results. I thought maybe it's taking a bit longer to show progress but I think it just doesn't work. Don't waste your money. I bought two from groupon and so did thousands of people.

I have been using this for 2.5 weeks and not even a small difference. Save your money to buy Latisse, it does work.

I've been using this product for almost about a year and i have seen absolutely no improvement. i have a little spot with missing eyelahes in my right eye and i have not seen them grow at all. i'm going to try tarte's multipleye lash enhancer next.
but don't buy smartlash cuz it won't do anything :[

After using it twice a day for 1 month, I definitely can see that my lashes are much longer and I'm losing less lashes than usual. It doesn't do much to thicken my lashes though, just lengthen. With mascara, my lashes sometimes hit my sunglasses. As another reviewer noted, if you get it in your eyes, it does sting.


The only other lash serums I've used are: 1) Rapidlash ($100) but after 1 use, it stained my upper lid purple (this wore off after a week) and I've heard this can happen with latisse, too. 2) Talika lipocils - I noticed mild lengthening but not noticeably enough to rebuy.
So, for $30 from Dermstore, Smartlash is great if you want more length for your lashes.

Got it online for 29.00 - marked down from over 100.00. Hmmm...certainly couldn't be anything wrong there. Did absolutely nothing for my lashes so I went back to generic latisse. My sister says SmartLash made hers longer and darker. Gonna send it to her!

I have to say this works. I got a really good price on it too. My lashes are much longer, I think they are thicker too, but it has only been about 3.5 weeks, so we will see. They are also much stronger, less breakage and less loss of eye lashes. I am starting to get a few really long lashes, crazy! They are at the outside of the eye, so that is good.

One of the better lash serums out there. I ordered a tube for the hell of it and used it twice a day. My lashes are nowhere as freakishly long as the results are portrayed in their advertisements, but I did notice some improvement in length, thickness and condition--I lost a lot fewer lashes using SmartLash than I have using other products. The results were enough for me to invest in another tube.


Another plus is that the solution is thin enough that I can use it both morning and night: I just let it sink in for a couple of minutes before I apply any eye makeup. Only giving it four stars because if it does get into your eyes, it can sting.


Cost-wise, it's not too bad, especially since one tube lasted me nearly 4 months with twice-daily application.


A heads-up: they've been running that "Limited Time Offer" on the Dermstore website for MONTHS so don't panic if you don't order right away. I also wouldn't run to sign up for that Auto Shipping if I were you, because I sincerely doubt they'd ever up the price to the $125 they claimed it's worth--it's not THAT good. $30 is a bit high but that's about the max price it's worth.

Smartlash is the second eyelash enhancing product I've purchased. I was disappointed. I did notice a very slight difference in the length and thickness, but not what I expected. I followed the directions and applied once in the morning and once at night and not much happened. I expected a dramatic increase in length like I had experienced when I used RapidLash serum. Also having to apply it twice a day was a little much for me. I would not purchase again.

I have been using SmartLash for a few weeks now and like what I've seen so far. It definitely has improved the condition of my lashes, they are stronger too. I tried Latisse and did not have a good result at all, it made my lashes fall out so I was very nervous about trying this product. I am happy to say that my lashes do not fall out with SmartLash. My lashes are definitely thicker but I haven't noticed a difference in the length, which may happen down the road. I do like the results I'm seeing with this product and will continue to use it. I know it retails for $125 but I got it for $29.99 with free shipping online at the Derm Store. Good luck~
