Its important to play with foundation and their textures to find which one (or seven) do what you need the best. Its especially exciting when you find a mixture with foundation that is out of this world. During my MAC days my manager (who is an amazing artist) said to me "the key to great artistry is mixing." Ever since that message was received ... I play! I found a very nice glow combination that worked perfectly for a shoot. By mixing a little Tom Ford Illuminating Primer with MAC Face and Body Foundation I was able to achieve the ultimate glowing foundation.  With some AJ Crimson cream foundation and a very little bit of powder this look was sealed! Do you mix anything with you foundation?
