I purchased Dior Diorshow Maximizer Lash Plumping Serum a couple months ago, and put it through the ringer, so to speak. According to Dior, the Maximizer contains hydrolyzed soy proteins and lots of other scientificky-sounding stuff. After eight weeks of use, testers found the Maximizer increased lash volume by 52%, lash length by 38%, and lash curl by 73%.
So, does it deliver? Well, I did notice some difference in my lashes, though I don't know how to quantify that difference. My lashes do appear a bit longer (though it is hard to tell in the pictures because my lash tips are blonde), and more voluminous. I wouldn't say the Maximizer caused my lashes to grow, rather it conditioned my lashes, allowing them to grow longer (without breaking) and have a longer life before falling out. I also noticed those fine little baby lashes grew thicker and longer.
Application is like that of a mascara. It has a spiky, silicone (I think) brush with a little nub at the end. The Maximizer is formulated for use under mascara, which gives you instant results, as well as on it's own as a nighttime treatment. You can use the little nub to apply the serum to your eyelid right at the lash line to get the serum right down into the base of the lashes so it will work while you sleep. I'm puzzled by the use of the word "serum" because the stuff is a white cream. When I think serum, I think of a light, almost gel-like formula, not a thick cream.

Personally, while the Maximizer did produce instant results when I wore it under mascara, it was a bit too much for me for daily wear. Furthermore, I found my mascara flaked off when I wore the serum underneath. After that, I limited my wear to nighttime and special occasions only.
Being that I am a visual person, I like to see results, not just read about them, so I have a lot of pictures.
More pictures after the jump - and I mean a lot more pictures!

For what it is, the Maximizer did give my lashes a little bit more presence, but not overwhelmingly so. I would not expect Latisse results with it, but with the option to wear under your mascara, you will get instant, attention-getting lashes.
Overall, I give Dior Diorshow Maximizer Lash Plumping Serum 3.5 paws up.
It does perform, but the flaking is a big minus for me. Plus, a full coat under the mascara is just too much for me, for the daytime, anyway. I did find that after wearing overnight, if I was careful washing my face in the morning to not rub off the remaining serum, I did have just about the right amount leftover on my lashes for a little extra oomph, without being too over-the-top.
Ultimately, though, I'm on to looking for the next best lash maximizer because the Diorshow Maximizer just isn't for me. If you'd like to try it out for yourself, the Dior Diorshow Maximizer Lash Plumping Serum is available at Sephora or on Dior.com, and it retails for a rather reasonable $28.
