I have used and loved this moisturizer for years. It works beautifully at night over my serum. In the morning, I use it again under sunscreen and my makeup goes on so beautifully over it. It hydrated my combo dry skin perfectly while not being greasy. It makes my skin look so smooth (minimizes pores like nothing else) and youthful. It also evens my skin tone and softens lines. Occasionally I run out and have to use something else before I purchase a new one and I notice a huge difference right away. Now I buy the 3.4 oz size, two at once!
