Givenchy Prisme Libre Loose Powder Quartet Air Sensation

For reference I'm NC45/50 and I'm using the darkest shade "Tender Sun". This powder is just pure luxury. My skin feels like silk when I put this on! "Tender Sun" consists of 4 cubes of loose powder colours - 3 dark-ish shades of brown and 1 light peachy apricot. This powder is so finely milled and has shimmers that are barely visible but just impart a gorgeous 'glow' on the skin. I use this over Mac Studiofix Powder foundation just on my cheekbones, under eyes (it's great over concealer) and nose. I don't use it all over my face because it has a highlight effect and I don't exactly need my whole face to glow like a beacon. I can't say it's great for oil control though, but I do live in a very humid climate. I usually use a brush for loose powder, but with this, I like to use the puff it comes with. The powder is so fine and light it tends to settle everywhere - on lashes, brows, my make-up counter (LOL), but I find using just a tiny amount helps lessen the fly-aways. This powder can be layered for a less sheer finish. If I'm just running to the store I just put this on with a little eyeliner and tinted lipbalm and I look polished and natural.
