It was great to use when I didn't feel like putting on full makeup! It's not a stark white cast, but a natural-looking tone-up, so I could just swipe it on and go, and my skin tone would even out nicely.
My skin doesn't really seem to be picky about cosmetics, so I'm not sure about any trouble. As for the sun care effects, I'm not sure - even after applying this, my face still felt a bit burned when I went out...
