I got this as a sample and have been using it for abt 1.5 weeks. While it's called a concentrate, it really is more of a facial oil. I cover 3 of my fingertips over the opening of the sample, tilt it back and forth once so that my fingertips have just a dab of stuff, and pat/massage it it on to even out the distribution. That's enough. I only have a sample, but there is still tons left!

For the first few days, nothing much seemed different. I'd been using Clarin's blue orchid face treatment oil at nights prior to this and while that left me with a slightly oily finish in the mornings (but not in a bad way of course, I like it!), the midnight recovery concentrate gives a dewy smooth finish. The lavender scent isn't over-powering, but it certainly is there when you first apply it. It goes away after a minute or so. Recently, I've noticed that my cheeks have started taking on a pinkish dewy glow in the mornings when I wake up and i attribute that to the midnight recovery concentrate! Who's to say what other good it'll bring with more use?

i'm definitely getting myself a full sized bottle when my sample runs out.

my favorite product from kiehl's- I love the lavender scent and this is very relaxing and soothing on the skin. it's natural, softens the skin and gives me that healthy glow :)

I've nearly finished my second bottle so it must be agreeing with me.

Pros:
- lighter than the rose hip oils but very potent
- just sinks into the skin
- doesn't have as strong a scent as rose hip oil
- I use it overnight under the Acai moisturizer
- no break outs
- my skin just looks better these days, I also apply it around my eyes.

Cons:
- may be a little light for those with very dry skins
- probably needs to be used in conjunction with a moisturizer for most skin types.

I don't get all the hype. Yes, it smells heavenly and you do wake up with glowing skin, but I think that's also a mental effect of spending $45 on AN OUNCE of MIXED OILS. I get the same glow from Argan oil (around half the price) and coconut oil (a quarter of the price.) Plus I can already foresee the horrors of using up this product, as the dropper becomes inefficient towards the end! I think the product is great, but it isn't worth half the cost.

Flight delayed, wandering around the fancy airport terminal...wander into Kiehl's, intending to merely browse and pass the time. The ingredient list on this serum were super impressive to me---all the key, natural stuff for dealing with discoloration and dehydrated skin: primrose oil, wild rose oil, etc. When I used it that night (after my flight--ack! dehydrating airplane air!)--I was pleasantly surprised at how light it felt: a soothing layer, rather than the sense of suffocation one might expect from natural oils. In the morning, my face looked well-rested and bright. Too soon to judge lasting results, but so far, I think it is quite lovely. The price is steep---but I can see one bottle will last a long while. I enjoyed the lavender scent, and that it comes from lavender oil (not added fragrance).

I bought this Sept 2010 and use most nights and still 30% let fso really economical ,a few drops of the oil leaves my skin looking refreshed and glowing by morning but the best thing is that my under eye dark shadows have disappeared and if I stop using the oil for a few days they came back eg I.forgot to take with me on a week away

I needed a serum and got myself a sample of this stuff at the department store. My skin became more hydrated and softer after the first application, but to not to jump to conclusions, I used up the sample first before committing to a bottle. The sample lasted for over two weeks!!!

It is winter over here now and I have extra dry skin. So far this stuff has helped a great deal! I haven't broken out in dry patches, rashes and acne like I have during previous winters... now, to look for a serum for the day time!

(ps: I used this under my moisturiser.)

There are few things in the world of creams and potions that surprise me these days. I have to say, after receiving this sample in store I am in HEAVEN. I have had many issue's skin wise, acne, redness, dryness, aging......in the instant this magic oil hit my face it all went POOF and my skin is literally glowing. It felt wrong putting oil on my face, until it was ON my face,lol. It soaks right in, leaving me with soft, hydrated, flawless skin. In the am my face looks rested and fresh. I have even ventured out of the house with only bronzer! No foundation or covering stuff up, why would I hide this glowing skin?????

I LOVE this product for use at night! Makes my skin glow the next morning and I've seen a drastic improvement in my skin through months of using this.
Don't let the big price tag and tiny bottle fool you; you really need maybe 2 drops to cover your entire face.
I gave the packaging quality a lower mark mainly because even though I'm no where close to the bottom of my bottle after months of use, I think it will be difficult to access the very bottom as the eye dropper doesn't go all the way down.

After using Kiehl's entire skincare, cleanser, toner and cream. I wasn't fond of any Kiehl's product. Beside being rather affordable compared to the other counter products, I think the entire skincare line work averagely. Nothing great shout about.
However, as I had the chance to ask for a sample of the Midnight Rcovery Concentrate, I put it to good use, everynight, after my toner, i use it sparingly (cause the sample was kind of little), then pimple treatment, moisturiser and leave-on mask.
I slowly realise my complexion improve. However, I didnt attribute it to the Kiehl's Concentrate. Until, I ran out of sample,and stop using.
Then I stared noticing all the products I pile onto my face doesnt seem to get absorp into my complexion. I started feeling frustrated.
At last, I gave in, and bought the entire bottle of Midnight Recovery Concentrate, and again, my face started feeling soft and smooth. Best of all, every products I apply after Midnight Recovery Concentrate get absorp into my face immediately, and feel so moisturised.
I love this product. And, sometimes, I actually use 4-5 drops for my face and neck. I know its too much, but it seems to be reallt working well for me, so I have no problem using it generously.
Do give it a try. I truly believe it will work for many people.
