I've been using Too Faced Primed and Poreless powder daily for at least half a year and am left with half of the jar. It costs US$30 for 0.16oz (about 5g?) which is pretty affordable. It's meant to be used as a "priming powder and finishing veil" that minimizes pores and imperfections for an airbrushed finish.
The powder is very light and finely milled. I like that it is not white - it has the slightest tint of beige and looks very natural. I have oily skin so I have to use quite a lot of it to mattify the sheen on my face, but once done, my skin looks smooth, poreless and at the same time natural! My daily make-up consists of nothing but Biore Tint Milk (tinted sunscreen) followed by this powder. I find Primed and Poreless Powder pretty good at oil control too! It lasts till lunch, then after blotting away the oilies, my face looks relatively fresh again.
It can give a powdery look in flash photos, but no white chalkiness (because it's not white)! And the best thing about it is the packaging - it has a twist plastic cover such that the sifter holes can be closed and powder won't leak out, which makes it super convenient for travelling. I always bring this on my overseas trips, very handy!
Ingredients: Silica, Populus Tremuloides Bark Extract, Lonicera Caprifolium (Honeysuckle) Flower Extract, Water/Aqua/Eau, Lonicera Japonica (Honeysuckle) Flower Extract, Mica, Iron Oxides (CI 77492, CI 77491, CI 77499, Bismuth Oxychloride (CI 77163).
The silica really helps to make skin look flawless, while the other flower extracts are supposed to be good for the skin (soothing and anti-inflammatory). The last ingredient is Bismuth Oxychloride, which some people are allergic to. It seems to be used in a lesser quantity since it's the last ingredient, and it doesn't irritate me at all.
In conclusion - I really like this! Minus 1 point because I have to use a lot to mattify my face, but other than that, I find it is a really good, lightweight finishing powder for oily and acne-prone skin.
