My Review: This is truly a great product. I sampled it first, and knew this is an investment for my skin, so I got the large size that comes with a pump. The best thing it does for me: With one pump (about a teaspoon) of this essence, I dab it all over my face. I immediately see the essence absorbing into my face and notice a visible change. I can see my face soften up (meaning face doesn't look blotchy, spotty, oily, red, etc) before my eyes. I know it totally sounds weird that I'm seeing change before my eyes -- almost like I'm hallucinating -- but it's true. I use it day and night. For daytime, SK-II helps control and balance the normal/oily skin combination. My skin with makeup looks flawless all day and I rarely need blotting paper even after moisturizer, primer, BB cream, power, bronzer, blush, etc. It prepares my face to absorb day or night moisturizer/makeup regimen. The instantaneous notice is pretty amazing, and I have seen improvement in the brightness and softness of my skin within two weeks of using this.
