I received a full-sized 30 ml bottle for free from Vichy, thru the Product Review Club, along with the Neovadiol Compensating Complex Day Cream and the Neovadiol Compensating Complex Night Cream.

They recommend that you use the serum day and night, underneath the day and night creams.
This serum has an easy-to-use pump dispenser that I love, and comes in a slender, tall attractive bottle which looks lovely on my dresser. ;)
It has an OK scent, a little perfumey for me, I think, but it's not too overwhelming and doesn't linger too long. The serum itself is silky and pleasant to use, it goes on smoothly and is very easy to spread over my face and neck.

I have used it most days and nights for 3 weeks, along with the other 2 Vichy products. My face is extremely well moisturized, and feels nice and smooth and soft, yet firm. We have been having some very hot weather, and perhaps it is a little bit of overkill for this season. After a few more weeks, I might save this quality product for cooler, dryer weather! It doesn't really make me feel greasy at all, but I do notice the slippery residue as I wash my face in the morning and evening.

I have't decided if I will purchase this product in the future, but if it passes the cold/dry weather test I think it might be a good one to have!

J'ai beaucoup aimé la crème de jour ainsi que celle de nuit mais pour le sérum, je ne sais pas vraiment. J'imagine que le fait de l'employer sous la crème doit faire une différence à long terme mais difficile d'évaluer les bienfaits pour le moment. Je vais continuer à l'utiliser.

I quite liked this serum. It made my skin feel very silky and smooth and was very easy to apply. I didn't like what I think is a eucalyptus type smell to this cream. I would prefer an unscented version, otherwise I probably would buy this depending on the price.

Ce sérum est parfait pour moi , il est facile a utiliser très crémeux et il sent très bon .. La petite pompe est génial elle empêche de contaminer le pot . C est un produit doux qui est tres efficace pour les femmes comme moi qui a la peau fragile

I received my free Vichy products about 5 days ago. I love them. I got the Neovadiol compensating Complex serum, the compensating day cream and the compensating night cream. I was so surprised that they were the full size products, and not just a sample size. I absolutely feel the difference in my skin already. I will continue using these products, even after my free jars are gone. I can purchase them at my local drugstore. Thank you so much to Chick Advisors for giving me the opportunity to try such a great product.

I used this product before applying either the Neovadiol Compensating Complex Day Cream or the Neovadiol Night Compensating Complex because it wasn't clear to me when I was to use it. Day or night?
That being said, I don't really have much to say about it's effects because I never used it alone. What I can say is that it was light. Only one pump of the bottle provided enough product for full facial coverage. You don't have to wait to apply your day/night cream after applying the serum as you wait for the product to dry. I just don't get it!

I have to say the truth < iam so careful person about my skin I tried thousands of brands and iam not easy to be satisfied but #TryVichySkincare! Neovadioal compensating complex serum is the best for dry skin
