After the first use of the Vichy LiftActiv Serum 10, I noticed that my skin appeared a little more softer and smoother- even more so, I woke up the following morning after having used it, with more softer and supple skin. My face wasn't dry, it felt moisturized and hydrated. I loved this as my skin gets drier in the colder months. My only flaw so far with the product, is the scent. I felt that the scent is a little too strong and pungent for me, and the way to combat this was not to use too much of the product at one time, and I see that with this product, a little does go a long way! However, so far I'm loving it, and want to continue to use it, so that I can have a more detailed descriptive use for the product after more uses!
