strobe cream has light reflecting particles in it and shimmer. it has a lot of really great vitamins for your face, and it also works on every skin type. it is more of a cream
studio moisture fix is more of a light lotion to me and has the feel of a primer after applied. it also has a lot of nutrients, but isn't as heavy feeling as strobe cream.
personally, I have combo skin and i use strobe cream on some parts of my face in the summer because i feel it is too heavy in 100 degree heat. you might want to think about something with a sunscreen in it also. that *never* hurts.
