I purchased this because I wanted to make my makeup last super long for a formal evening function a few weeks ago and have been using it for the last month. Super happy to see it on BR because it's both my first and favourite matte pressed powder!
I do a lot of in-front-of-camera work and shiny skin is the bane of my existence. This stuff instantly mattifies and, if you get one of the tinted versions, smooths out your skin tone. I prefer using 01 Transparent though, so that the contouring is seen clearly. It pats on white, buti f you blend it with a fluffy brush, it goes transparent. You can try on your hand to see for yourself. I have combination skin, but recommended to a friend with very oily skin (teenage woes). No matter how oily you are, it will mattify. Magic.
It also definitely makes creamy foundations longer lasting. I was using some foundation sticks that have a creamy gel formula and I found they were wiping off quite easily and also shifting around the place. The powder kept it in place flawlessly without any touchups at all for 8h, which I thought was pretty impressive.
I love this, it's so affordable! Complete Rimmel London fan.
