I was excited to try the Vichy Aqualia Thermal Dynamic Hydration Power Serum but I feel so let down. Something in the serum made my eyes water and itch all day long. I'm not allergic to anything so I'm not sure what it is about this product that my skin didn't like. I did like that it was easily absorbed into my skin and didn't feel greasy though, and the scent was mild and not too bad.
While I appreciate the chance to try it out, I don't think its something that I'd buy in the future.

I used this serum daily for three weeks, twice a day and noticed very little difference in my skin's hydration. I usually applied it after I washed my face, applied toner and before moisturizing. When I applied it, it felt like it was slipping and sliding across my face rather than being absorbed into my face. The product smelled pleasant and didn't break me out, which are pluses.

Why are all of these product so scented?
I did not notice a difference with this product. If anything it made my skin worse. I've been using professional products and having to switch to these was a nightmare.

I received a bottle of this serum to try for free from Chick Advisor. I was really excited to try this line and it is pretty pricey, so it added an extra thrill. I immediately moved all of my previous products to the drawer and only used this serum in conjunction with two other products.
I have combination skin with some very fine lines.
The packaging is beautiful and has a pump, which I love. This serum is the best out of this line. It was lightweight, easy to apply but was a bit sticky (which fades after a minute). It leaves a bit of a shine. The smell is fairly neutral, struck me as a light floral but wasn't overpowering. You can feel an immediate difference in your skin after the first use. My skin felt cool and almost tingly. It felt like a barrier was being applied to my skin. It felt like it was trapping moisture rather than adding. It never felt like it was being absorbed, just lingering on the top.
I used one pump, morning and night, as directed and it covered my whole face and neck with a bit to put on the top of my hands. (The bottle lasted the whole month) There were a couple of days that the serum was the only product I applied. I did break out quite a bit but I don't think it was the serum that was responsible for it.
Over the course of the month, my skin didn't seem to improve as far as moisture and I proceeded to become very oily in the places that I was dry. I didn't notice any change to my fine lines and my skin feels better naked. I noticed no real benefit to using it and I wouldn't buy it personally. I certainly don't have any dry spots on my face anymore but my skin feels heavy and greasy. Not a positive experience for me. My hands, however, look great! The moisture barrier felt good on that type of skin.
