It seems to be oily, so it breaks down quite a bit even in December. I'm worried that if I use it in the summer, it will run off with sweat. If you don't apply it evenly and carefully, streaks will become noticeable. Of similar products, I think Orbis Smooth Matte suits me better. I chose the shade Natural 01, which is about the same brightness as Shiseido's Ochre 10.
