I've never used a serum that made my skin feel quite like this.  There are only so many synonyms for "silky" and the word just seems overused but that's how I'd describe the texture of my skin after using this not only for one week but just after one use.  Unlike some facial oils, the Couleur Caramel Anti-Aging Elixir is a product that you use underneath a moisturizer. The one I used was the Couleur Caramel Anti-Aging Fluid which, interestingly enough, is designed for normal to oily skin, whereas the majority of anti-aging products are geared towards dry skin (check out their Anti-Aging Cream if you have dry skin).  This should be a welcome surprise for those normal/oily types.  The combination of these two products left a fabulous smooth texture to my skin and the consistency of both is not greasy in any way, despite any preconceived notions you may have about using oil on your face.   The aroma is very mild and fresh and they both sink in very quickly, which makes them both a great base under makeup.  I used these two products for one week so I can't attest to their anti-aging abilities, but I can tell you that the texture of my skin felt great and I had a difficult time not touching my face because it felt great!
