Does it seem that the fancier the item, the longer the name? LOL... my humor. ^_^ I'll put the product info at the bottom. Visit Estee Lauder's website here.
I've been using a sample size of this product for more than a month and I really really really like it!
I'm not a fan of this type of packaging. For this one little bottle that can easily set you back $80 for the 1.7 oz version, this type of packaging will not allow you to get every last drop. If you go with the conversion that there are about 450 drops per fluid ounce (viscosity of the serum is taken into consideration) and the 1.7 oz bottle holds 765 drops, that's about $0.104 USD per drop. And given the type of packaging this is, there is bound to be a couple of drops that you won't be able to get.
Repairing fine lines
I still have fine lines under my eyes and around my mouth. However, when I use this product I feel as if it smoothes out the lines a little bit. I think this product works through absorption and by filling in the lines. The thing is, I believe this is best used at night when you're resting and your skin has a chance to repair. So while I don't notice a dramatic improvement, I can safely say that my skin isn't getting worse, either.
Evening out the skin
In my experience, I think this product does do a fantastic job of evening out my skin tone. It seems to take most of the redness away from around my nose and mouth. It's going to seem weird but I think that this product doesn't get absorbed fully into my skin and I believe that's a good thing! After applying this product and letting it set, I can't help myself sometimes and touch my skin to feel how smooth it is. It feels a little bit like a primer, but not as powdery or dry. It retains a bit of moisture... for me, at least.
So judging by my last statement, yes, this product does provide some hydration. But this is no excuse to skip moisturizer. Serums still need to be locked to skin with a moisturizer to boost efficacy.
Now this statement, I truly can't say. I think the only way to prove this is to do an experiment with two sample populations with similar lifestyles and living in similar environments. Your control group would not use this serum, and the experimental group would. I think that's the only way to see if this environmental repair claim is true. However, for all the other benefits, I think we can afford to let this claim slide a bit. ^_-
Okay, now read on for the product information, which I copy/pasted from the website. Remember to visit the website for more information and product comparisons. ^_^
