Seems like the same product I normally buy, only in a mini size, which is what I wanted for now. One of the only primers I like. Packaged neatly and arrived intact. No complaints

  • Great Conditioner/Booster
Size: Full Size
All Lancome Cils products that I use are awesome. I use their definicils mascara. I use their Cils Booster for lash conditioning and lengthening before applying mascara. It is easy to apply and really does provide the lengthening you want. Doesn't clump. Separates well. The tube lasts a few months, so it's long lasting. And isn't outrageously priced. A find it to be a good value and a very effective lash lengthener. Lashes look natural and long. Love it! ... show more

  • This went on great as an eyelash primer
Size: Travel Size
I like this eyelash primer way better than the Loreal one I bought first to try because it was cheap. This one is creamy and goes on pretty smoothly. I put it on the middle out to the ends of my lashes and don't worry about trying to get it on the roots so much. Then I apply my mascara before the primer is totally dry. It makes everything less clumpy. I do one eye at a time so it doesn't dry too fast before I can finish. It may be a little pricey, but it is worth it to have less frustration when getting ready in the morning. I also like that it was a travel size so I could try it out before committing to a big, more expensive tube. I'd recommend it for sure. ... show more
