Eminence skin care line comes from Hungary and it uses natural products (fruits and veggies). It does not fall into category of medical strenght skin care but natural products and antioxidants will definitely help you improve and maintain glowing skin. I first experienced stone crop mists and relly liked its fragrance. It was part of my regular routing to moisturize my facial skin when I lived in Florida. When I came across the serum version I knew I had to have it and I never regretted it. I typically use it in the morning under my day cream. I gets absorbed by the skin quickly. Do not let green color scare you. After it is applied on the skin, serum is completely colorless. And fragrance is just as majestic as it is in the mist. Thsi serum can be used day and night, but personally, at night I like to use more potent medical grade products that can "work" on my skin while I sleep.
