"[This review was collected as part of a promotion.] I received this product to test and after 2 weeks of use I am pleasantly surprised. It has a light fluid/gel type formula and is instantly mattifying. But not only instantly, the mattifying effect seems to last throughout the day. I have a very oily/greasy tzone which only worsens throughout the day with air conditioning in the office etc but this product really helps. I find by the end of the day I only have a light sheen on my skin rather than looking like I've just been for a run!! You only need a small amount of the product and one bottle should easily last at least a month. I would definitely buy it myself and I would recommend to anyone with oily skin."
