Giorgio Armani Beauty Lasting Silk UV Compact is a powder foundation with a mattifying finish. Its Micro-filTM powder particles smooth the skin for a natural, long-lasting finish while also providing light diffusion to illuminate the skin's surface. It is amazing as a setting powder on a liquid foundationto give your complexion that airbrushed effect. Perfect for dry skin, over a hydrating foundation as it finishes your look, keeps your glow and makes the liquid foundation last all day. For oily skin, again perfect - mattifies but doesn't flatten the complexion.
