With just one sweep, this innovative mascara primer glides on and evenly coats and smoothes your lashes to maximize the results of your favorite mascara.

This was my very first time trying out an eyelash primer and let me tell you there's no going back. This primer is Simply Amazing. I mean you legit have to try this out yourself in order for you to understand how life changing this primer is. This gives you length. This gives you volume and this is all before you actually put on mascara. Once you put on the mascara it takes you on to the highest level of amazing lashes. You will for sure get compliments. You will for sure be asked if you are wearing falsies. You will also not look back to the days of wearing mascara alone. Lancome did an amazing job with this product here. It goes on white and it sets pretty much white period but with one coat of your mascara the white is gone you can't see it...you're just left with the volume and the length of the primer. I will totally recommend this to everyone.

I think my reason for this purchase was I had a coupon so I figured I would use it to try this out. I was a bit skeptical at first because I don’t always believe in lash primer or ever seen a difference when I have used them in the past. Boy was I blown away by this one! I bought a travel size one to try it out and it works wonders so of course I had to buy a full size. I would highly recommend this product! I literally can’t live without it now! I get tons of questions about the mascara I’m wearing but honestly it’s b/c of this lash primer! Helps them stay curled and lengthens with any mascara. I like it paired with monsieur big mascara.

Want an instant lash boost? Apply this after curling your lashes and just before putting on mascara. Works like a charm! I combined this with benefit's "they're real" mascara and I've literally been asked "are those your real lashes or are they falsies?" The only downside of this product is that it can weigh down your lashes. Sometimes I re-curl my lashes after applying mascara, but that's risky since you can pull out some lashes if you aren't careful. For that reason, I usually pair this with a mascara that can hold a curl.

I NEVER put on mascara without putting the Lancome Booster Base before-hand. It's an absolute necessity. It almost acts as a conditioner for your lashes. You wouldn't apply powder/foundation without a primer first, correct? This booster is literally that for your mascara.

It makes my lashes longer, separated, and soft. When I apply my mascara (preferably Lancome's Monsieur Mascara) it only magnifies the look. It makes them fuller, without question.

I absolutely love this product! 5 out of 5 stars!

Review for: Lancome Mascara Base more...
I received a travel size sample of this product in my January Boxy Charm box. I do prefer travel or mini sized mascara products because they dont dry out as quickly.
I have never tried a lash primer and honestly would never buy one, I wear Falsies everyday. But this product is awesome. Not clumpy, easy to apply, doesn't flake off and dries fast. Smells good as well. I definitely use this when I don't wear false eye lashes, to make my eyes POP.
Keep your receipts. Most stores have great makeup return/exchange policies.

I like it enough. Makes my lashes look nice and full before I apply mascara. I recently used it and compared it to Loreal's primer and noticed that there isn't a huge difference between them for my lashes... so while I think this is a nice primer, I do think there are products with similar results at a much cheaper price so don't think this is truly worth the extra money. If I continue getting samples of it along with other products or in subscription boxes I won't not use it though

I think this mascara primer is just okay. I put one layer on and I found that some lashes were coated more than others. I think it dried down really quick but if I do not put my mascara on quick enough my lashes are very hard to the touch. When I put mascara on after, I do not see a big difference. I think this product is unnecessary for a daily routine because it does not make a huge difference.

I received a sample of this in my Sephora Play Box and at first I was a little reluctant because I didn't really see the need for a mascara base - boy was I wrong! The base was super easy to apply and once I put my every day mascara on top my eyelashes looked much longer, didn't clump together, and fuller. Wow! I think I may have to invest on a full size bottle of this!

I received this product in my Sephora Play monthly subscription, and I think it does boost my lashes, but I wouldn't go out and purchase it, because I know Lancome is quite pricey, and also don't need to add another step to my makeup routine, but if you are someone that doesn't mind the price, or adding another step to your makeup routine, than I would recommend it.

Does it help if you sleep with this product on your eyelashes ? Because I was at Sephora and a sales associate asked me if I have ever tried to sleep with it on my eye lashes and I said no and she said I should try it . Does it really help them lengthen and grow faster and fuller ?

I have been eyeing this for a while but have yet to purchase it because I am not sure this is worth the investment considering its high price. For those who have tried it, would you repurchase? and why?
