I originally got this in the Sephora Lash Stash holiday gift set Christmas '14 and didn't think too much of it (mascara primer in general, actually) since it was dual ended with Clinique High Impact and I'm not too familiar with Clinique products. At the time, I was about a month or so into my desicion to grow out my natural lashes after having lash extensions for almost a decade and my lashes were awful - short, brittle, sparse.. Ick. I was in search of that "perfect" mascara that would save my lashes from despair, and was hoping that there was one in this box. Tried majority of the mascaras without the primer, and honestly wasn't impressed. It wasn't the mascaras that were the problem, it was my sucky lashes. I got bored one "off" day and decided to try this primer with the high impact mascara. It was a total game changer, not even kidding. I did one eye with primer and high impact, and one with just high impact. DRAMATIC difference. I remember thinking "why didn't I try this primer in the beginning?!" Every day, I tried this with several different mascaras, high end and drug store alike, same results. My lashes actually looked NORMAL instead of looking skimpy and pathetic. They were thicker & a bit longer. since the discovery of primers, I hate using mascara without one (and rarely, if ever, do) because it just isn't the same, even though now that my lashes are completely grown out. Since this was my first primer, I didn't really have anything to compare it to. Since then, I have branched out to other primers. This one in particular gets 4 lippies ~
The price is right as far as high end primers go.
The results are noticeable.
It does condition lashes nicely and makes them kind of flexible.
It doesn't smudge or flake ANY mascara, and I have oily lids. In fact, since I've started using a primer (except for Loreal Superstar, that primer SUCKED and it smudged every mascara I tried it with, I actually did a review on it awhile back) I have no more panda eye! ????
Works well with pretty much any mascara.
I hate to say it, but I agree with the reviewer that mentioned they couldn't find the ingredients anywhere. After doing research and desperately wanting to boost my lashes healthily, I figured any help would do and since I wear mascara every day, might as well use a primer with a growth complex instead having to stick with one particular mascara that contains a growth complex, such as Rimmel. I wanted to know if, over time, this would grow my lashes like Lancome Cils Booster XL claims (which I tried after this and kinda loved. I may have to do a review on it soon) and wanted to do a comparison of the two ingredients. Nope! None available anywhere on the net for this product. Of course, I have repurchased since the original one from the kit, but only because my local Sephora didn't have the Blinc primer I wanted to try, and I was desperate. The 2nd tube wasn't as wowing as the first, but by then I discovered Lancome Cils and fell into lust. And yes, my lashes do seem thicker in growth since using as a base. By then, this one didn't do it for me alone, but when I pair it with LCBXL or Blinc primer, which I have since purchased, holy cow! It definitely still boosts mascara, or maybe it's boosting the other primer, I don't know. Whatever it is, it works!
Overall, I would definitely recommend it, especially if you're a high end primer user on a budget. I've compared this to Loreal Superstar mascara/primer and Cover Girl extensions primer/mascara duo. No comparison to either drugstore primer, and this is only a few dollars more. With the price being so low (15 USD) and it making even Wet & Wild mascara capable of looking like false lashes, I think it's an affordable additive to any mascara junky's arsenal. I may repurchase a 3rd time somewhere down the road, but for now I'm on a mission to find that "perfect" primer with long term benefits, because Cils Booster XL and Blinc aren't doing it for me alone (neither one volumize to my liking) and I can't double up forever (;
One more thing, a full tube lasts foreverrrrr so it's definitely worth the $15. It also doesn't get all chalky the way Tarte MultiplEye did. It dried beyond use after a week! I couldn't even revive it with eyedrops. It then became wet chalk. NEVER AGAIN. Anyway, the tube I have of Lash Building, I got in January and it is still a creamy formula, not clumpy or chalky. I also find that it works best if I let it sit for about 30 seconds before applying my first coat. I tried letting it dry, but did not like the way mascara was applied over it. Actually find this true with any lash primer I've used, but it may work for someone else to let it dry or apply right away.
