HD Powder is a silica-based powder that is not micronized, and will not flash. A light beige color. Needs to be lightly applied with tiny amounts to any area where you need diffusion or to cut shine. Silica disperses sebum and so is great for getting rid of shine without putting a lot of pigment on the face. Great for mature skins and HD cameras. Packaged in a refillable shaker bottle.
