Glamour Try It: La Prairie Skin Caviar Essence In Foundation. This wonderful Glamour Try It Foundation is infused with caviar water. First of all, it went on effortlessly and I liked the weightless feeling of it. Most make up afficianados know that not only is foundation the most important part of your make up program, it can be your only makeup for the day or it can literally be the foundation of an entire make up look. I really liked this foundation and I think that La Prairie has a winner with this one. I will definitely say this is a must buy.
