I have tried to upload my review to the product page but with no luck, so I wanted to share here!
I absolutely love the One/Size Ultimate Blurring Setting Powder because it sets everything beautifully. I tested it with both a long wearing foundation and a CC cream and it definitely lengthened the longevity of both. I have oily skin and my makeup still looked flawless at the end of the day when using this powder with a foundation, however, with a CC cream, I found that some shine did creep in towards the end of the day and I do think if your skin is on the drier side, this may be a little too mattifying. I also loved the packaging for this, it is really functional and the additional flip lid inside that keeps the powder in is a lovely, hygienic feature. The powder itself is very soft and fine and the powder comes out easily. Overall, I love this product and would definitely recommend it, particularly to those with oily skin!
