Review (5/5): It works very well, is cruelty-free and is very reasonably priced
This is a really great product! I only use it to fill in areas of my eyebrows that have never recovered from unwise overplucking, so I can't comment on how this does or doesn't work on eyelashes, but as for eyebrows, it works (I suspect it would work for eyelashes too).
This is one of quite a few similar products that are available from a multitude of companies and most of them work, but this one has an important difference: price.
I initially purchased this because I couldn't find the serum that I had been using. That serum also worked, but it was about $70. It is common for these types of serums to cost over $40 and even around $100.
So, how great to find a product that is every bit the equal of the more expensive brands and this one is *cruelty-free* (no animals were experimented on to make it- people would be surprised how many cosmetic brands subject animals to painful experiments- you can easily google to see which ones) too!!
Also, I just recently bought my second bottle after months and months of use. It LASTS.
Now, like any of these serums (or even prescription Latisse), this only works while you are using it. I skipped this and other serums to see if the eyebrows that had grown back would remain and, no, they don't.
Still, this takes a few seconds to apply and even I, who am pretty tuckered out at the end of the day and have many chores to get done before turning in, find it a very easy addition.
