Does rice water really have a whitening effect?

You know they say washing your face with rice water has a whitening effect.

Has anyone tried this?

Even after using products from the whitening line, I couldn't really tell if they had a whitening effect.

Of course, that might be because I didn't use expensive cosmetics.

I've heard that while some folk remedies are misunderstood, they are more effective if used consistently.

Will consistently washing my face with rice water really have a whitening effect?
