I got the "Physicians Formula Eye Booster 2 in 1 Lash Boosting Eyeliner and Serum" from the company when the company had a giveaway of them on their website. Overall this product sounds too good to be true, so I was excited to try it and see. I love Physicians Formula as a company in general, but have only tried their bronzers, so I was also excited to try some different kinds of products from them. Overall, I love this as an eyeliner. It draws a super dark black line. You can make it as thin or thick as you want, which is a great way to control your look. I love it and have been using it everyday for a while now. It has actually lasted a really long time. I would definitely recommend it as an eyeliner. While its a great eyeliner, it did not "boost" my eyelashes at all. I do not feel like they are any longer, thicker, or fuller at all. So if you are looking for an eyelash growth serum, I would recommend looking elsewhere.

I received this product as a free sample. I usually don't use liquid eyeliner because it is usually hard to put on and you get uneven lines. This product makes a nice clean fine line! I love it. I noticed today that my eyelashes seemed longer. Even if it didn't make your lashes grow I would still purchase this product. I love the ease of it!

I received the Eye Booster 2-in-1 Lash Boosting Eyeliner + Serum as a sample from Physician's Formula. Here's the thing: I do not wear eyeliner because I do not like regular liners and every liquid liner I've used in the past has made my eyes burn so badly that I couldn't even keep them open. So, needless to say, I was very hesitant to try it, even if it was a free sample of what sounds like an amazing product! After about a week of looking at it every time I opened my drawer, I decided I would give it a try. And..... no burning!!! That is why I think this is the best eyeliner ever: simply because I can wear it. :) There are other, more universally appealing highlights, though. It is the shape and size of a pen, which makes it easy to handle and apply. The tip is not a marker-style tip, but a perfectly sized paintbrush tip. It goes on smoothly, evenly, and easily. It last all day. Without the lash serum, it is worth buying this product. I cannot comment on the lash boosting properties because I haven't used it enough to see a difference, but if it really does improve my lashes, then that's a huge bonus for me!

I was very skeptical about this. as i tryed other with no results. but after one month of using this i see my lashes growing . It is easy to use , you can make a small thin line with out and trouble. stays on all day . and comes off easy. i use face wipes make up removers .

I love this eyeliner! I had so much trouble using a liquid eyeliner before but this eyeliner made it very easy for me. It goes on really smoothly and I love the fact that my eyelashes are lengthening while I am using it!!! I haven't tried it on the waterline yet, just the upper lid. It is also easy to make the little wingtip at the outer corner of the eyes, which I LOVE. I gave 4 stars because when I put a thicker line on my lids, it seemed to disappear and flake off...it was supposed to last 24 hrs? However, I have those creaseless asian eyes...so that might be just for me. When I had a thinner line, just lining my lashline, it did stay on, for a very very long time. Overall, great great eyeliner!

My five star rating is based solely on the product as an eyeliner. This product is a liquid liner that contains a lash length boosting complex meant to visibly enhance lash growth in as little as two weeks. Although this product is designed to boost lash length, my lashes are naturally long and it would be hard for me to notice a significant difference in length. That centainly doens't mean my lashes haven't grown from the product, it just means I'm not the best case study to prove they did. The product as an eyeliner is excellent however, so if it does end up making your lashes grow it would be a real bonus. The liner container is about the size and shape of a pen. I think this really makes it easy and comfortable when drawing the liner on because it feels very second nature unlike some other liquid liner applicators. I have yet to make a mistake using it. It lasts all day and stays put until you take it off as well. It looks very natural and makes your eyes pop. What can I say? It's a great liquid liner with an ever better applicator and the bonus of natural lash lengthening. 5 stars!
