***EDIT*** 3+month mark: Since writing this review, I have seen a marked difference in my lashes. It was like they suddenly all shot out to the same length, especially on the sides. They are very, very long. Though i have also found some of them grow in unusual ways (curl the wrong way and scratch my eyes, or become ingrown), and there is a lack of curl. They look fantastic with a little mascara though, and still very natural. I get a lot of compliments.
2months: A good cheapie. I obviously use the word "cheapie" in comparison to the $200 lash serums on the market, and considering the obviously smaller price tag, this is a good product. Now, while I have found there's growth in my lashes, it certainly isn't obvious (I do have long lashes anyway, so maybe it'd be more obvious if they were short?). I was hooooping to find a product which would mean all I had to do was tint and curl and could ditch mascara forever, sadly not the case. I also found the growth uneven. Some lashes seem not to have changed, while there are 3 or 4 lashes either side that just decided to sprout ridiculous lengths, as if I have a few leftover extensions. Having said that, I read somewhere that this one takes around 10 weeks to really give the best results, and I've been using it about 2 months- which brings me onto my next issue- one tube lasts three months?? Lies! Maybe I use too much? I'm onto my second tube of the stuff.. After one tube I noticed nothing, but I was told to persevere (Hear me, ladies! Thou Shalt Persevere!!). So I went and bought my second tube and after about the half way point I started to see the random long lashes poking their heads out and grasping onto mascara. This product has, on occasion, given me an ever so slight stinging sensation on my lids, but that's only if i'm being over zealous (and I am, so often, a little over zealous in my application- driven purely by the lust for long lashes!), and it goes away after a few minutes. It's not given me any redness in the skin or irritation, but do mind the eyes, especially if, like me, you apply to the lower lashes, because it's much easier for it to seep into the eye since you apply beneath the waterline (I suppose you could apply under the lower lashes, but that's fiddly and I'm lazy!). The stinging isn't bad, I probably should wash it out but it's so mild that I don't bother. All in all, yes, this product does work, but you're going to need more than one tube, and you must apply it religiously every night! Worship your little tube and it will bring you happiness. Fail to comply, and you've wasted $70. I think for quick results, or really dramatic results (if they DO exist), maybe spring for the pricier ones, but this one works a little better for my budget right now.
I decided to try this despite already having long lashes, mainly because I was beginning to feel left out from all the people who's lashes now appeared longer than mine from using these sorts of products and falsies. This was recommended by a friend who was onto her 3rd vial, so I knew she meant business. I used the product on my lashes every night and on my brows once in a while to 'fill in the gaps'. It definitely worked. After around two weeks of using this product I decided that my lashes felt too long and stopped using it, passing it onto another family member who needed it.
This product is definitely worth a try, after I stopped using it I did not find that all my lashes fell out as some people complain of in other eyelash serums. Overall a great product, but I probably wouldn't use it again, only because I don't feel the need to.
Tips: Use to fill in gaps on your brows as well.
