This is a holy grail product for combination/oily acne prone sensitive skin. It has drastically reduced redness and irritation. It has also within the first use reduced the midday oil slick my face used to develop. I use this in the morning and another product that is more hydrating in the evening. I first tried it as a free sample (thank you Paul Labrecque!). The cost of the bottle prevented me from ordering the full size for awhile. But after I received and tried a second sample it felt worth the investment. I'm still working my way through the first bottle, and my only hesitation would be how long it lasts.
