I love this stuff, I'll use it both under and over makeup or just on my bare face, when I want to keep it matte looking. So many product try to be this, and they fail horribly, this is it! It doesn't look like much, but just dab your sponge that come with it into the product and dab/pat it onto your face, helps fill me my pores, makes my face so smooth and soft feeling. It does keep me matte. When I use it over foundation during the day when I get oily, I thought this was such an odd thing, but it really doesn't move my makeup and re-mattifies my skin. Little goes a long way.
