Makeup artists have long known that a light dusting of translucent powder prior to applying foundation allows for smoother application and a reduction in the appearance of enlarged pores. Now, Primerstone makes this makeup trick available to everyone, with the added benefits of SPF. Foundation applied over this canvas will have more staying power. Primerstone is a pressed-powder based, SPF15 primer that evens out skintone, reduces pores and creates a clean, receptive canvas for foundation application. It contains laricyl, a mushroom extract that acts as a gentle astringent, minimises pores, and provides long-lasting hydration. Platinum in the product works to stimulate cell turnover and its light-scattering effect also helps to reduce wrinkles. Other ingredients zinc, magnesium, and mica allow for compatibility with both mineral-based and liquid foundations. Metallic elements help give the powder heft, and the fine-milled texture bonds seamlessly to the skin's surface. Available in one universally flattering shade.
