Review on Revitalize Your Skin With Philosophy'S Turbo Booster Vitamin C Powder by Tyler Spencer

I use this stuff on and off throughout the year. I mix it with Hope in a Jar but have used it with other moisturizers too. It does brighten darker spots and it tightens skin a bit. I tap bottle against counter to shake up powder then just jiggle a bit out rather than using the little scoop. Do wash your hand soon after--I find the area I mix it in my palm can stain brownish (but doesn't do that on face?!)
