Actually, it has a good power to give my skin a little brighter than before, but not for a long time brightening. And also, because it is a clay mask, I usually use it as an exfoliating dead skin cell after wearing a long-use make up. Well, it's good enough, and worthy to try.
Kinda hate the result when I wash the mask off, because it leaves white residu on my skin. So I should be double-crossed to remove the residu with hydrating toner, and apply it with cotton pad when I basically applying toner directly with my hands to minimize waste product.
