Update:
I used this product for 5 months - it made my skin smoother but no difference to any of my dark spots.
I've uploaded photos from when I started (April) a few weeks later in May, and again in September. I almost feel as though my dark spots got worse.
I also used this with the day cream.

It smells good and feel light to apply it on the face but it doesn't do a lot on my acne marks or dark spot. if I need to pay for it myself, I don't think i will spend the money on it.

I've been using this product for almost 5 weeks. Honestly, I'm not seeing a difference. I've been using it with the ProEven Advanced Daily Dark Spot Corrector (almost 3 weeks of use). Maybe I need to use it a little longer. My skin is generally very sensitive to products and I have very dry skin as well. I haven't had any problems with it or had issues with my skin drying out. I will continue to use it until it's gone to see if there is a difference.

I had an allergic reaction to one of the two products & had to stop using them w/in three days, so I can't really have an opinion on its effectiveness.

Editor's Note: if you have questions regarding the use of this product, you can contact L'Oreal's Canadian Consumer Care Center (information is printed on the box).

Same as with the day cream, after using it I have experienced slight breakouts. I do not notice a difference in my dark spots, though it may need more time of using to see a difference, even slight. For the price, I do not think I will continue using it though.

I usually don't use serums b/c in the past they've made me break out. I got a tiny sample of this one in the mail and tried it out, and yay no breakouts. Therefore it's a lighter consistency serum. I used it at night primarily under my eyes, nose, and places where I know I'm starting to see fine wrinkles. I liked the light scent of the product, a clean luxury smell. It's a clear liquid product and was smooth to the touch and absorbed/evaporated quickly without leaving greasy spots. I felt it was effective in providing added moisture overnight to the face, which I believe improves the appearance of skin. I would keep using this product, but also think it's a bit overpriced for what it does(moisturize).

The gel is light and absorbs fairly quickly into the skin. It doesn’t leave any greasy feeling or icky residue on the skin.
It seemed that some of the dark spots/scars were slightly fading, when in combination to the day Pro even that was also given to me to try by ChcikAdvisor c/o Vichy. Paraben free and suitable for sensitive skin.

Also have had improved skin texture and radiance since using this product.

I received this product by mistake from Chick Advisor, but they have since sent the proper (daytime) product. Vichy ProEven Night goes on smoothly and absorbs quickly without being greasy. It also gives the skin a refined look I would expect more from a daytime product. If it is making any difference to my dark spots, it is happening so gradually I cannot be sure it's doing anything. I think Vichy makes wonderful products and was excited to be testing this product. I will finish using the tube, and only then will know for sure if it's worth the price.

I received this product for free as part of Product Review Club.

I'm still hopeful that this product will take effect, which is why I'm giving it a "You Betcha" rating, but as of yet, I haven't seen results. I've been using this as a once-a-week night mask, as directed on the package, but I'm wondering if maybe I should do it twice a week or more often.

The pros:
- the smell is AMAZING.
- it's not greasy at all
- my skin looks brighter in the morning

The cons:
- dark spot scarring from acne have not disappeared or lightened after three weeks usage.
- very expensive for a product that I still haven't seen results from

I received this product to try free and have been using it for about 3 weeks now. I haven't really noticed a difference in my older larger very dark spots, they seem unchanged. But, a couple of my more recently acquired dark spots on my nose do seem to be a bit lighter in color. I have been using this in place of my regular night cream and it does leave my skin feeling soft, but a bit sticky. Overall, I will continue to use this to give it more time to see if it can really lighten the appearance of my dark spots. As far as the price, it does seem a bit pricey, but if it delivers then I would say it is worth it.
