Ok, I can safely assume I have finally found my HG powder. I have dry skin, so powders with any oil control can have a more drying effect. This has no oil controlling properties so this is perfect for me! It has no colour, doesn't add shine (more of a subtle 'glow'), and doesn't mattify. So what is the point of this you may ask? This sets my makeup perfectly, and gives the a more pulled together, finished look. It quietly softens any imperfections without looking powdery and cakey. Its undetectable. Suqqu claim that this also 'keeps the moisture in the skin'. I could probably say is true, as I do not feel that my skin is drying out as the day goes on. By the way, you get 15g of product all housed in a beautiful container :o).
Expensive? Yes! Worth it? Yes, yes, yes!!!!
Suqqu Nuancing loose powder in Natural is, bar none, the most luxe powder to ever caress my face. It is soft, skinlike rather than matte; it is feather light; it is invisible but in a good, pore-blurring way. Like the actual Grail, it's incredibly difficult for most of us to get a hold of, but it's the absolute best. I still love my KGD Maifanshi, but it's just a mite more substantial feeling than this, a powder that could convert the most stalwart powder-hater.
