Tone-up sunscreen

I've tried a lot of tone-up sunscreens.

I haven't seen it actually get brighter.

The old Abe or mineral sunscreens definitely brightened the skin tone...

Are there any organic sunscreens that really, really brighten the skin tone?

If I apply sunscreen once in the morning during the summer and then put on foundation, I'll be affected by UV rays by the afternoon, right?

You should only apply sunscreen so you can keep reapplying it.

I want a non-greasy tone-up product, even if it isn't quite as good as foundation.
