I like it. It’s thin and sheer-ish, but buildable, sort of like a BB cream in gel form.
It’s not as mattifying as its name suggests, though. I felt oily in my T-zone after wearing it for several hours without primer. But I didn’t LOOK oily. The shine just showed through as a slight dewiness.
The next day I used it over top of my ELF mineral primer (always use silicone-based primers with silicone-based foundations, and water-based with water-based!) and it worked much better, though I still wouldn’t describe it as totally matte. My Covergirl 3-in-1 foundation is much more matte.
