If White Perfect D1 is a treatment cream, focus in pigments, freckles, brightening and exfoliating skin. Then, White Perfect D2, night cream, focus in nourishing from deep inside of the skin, recovery the new skin, anti free radical, antioxidant and anti aging.
White Perfect D2 helps the skin recovery faster after skin treatment with white perfect D1.
Beside, white perfect D2 also brightens and hydrates the skin, and tighten the pores.

My experiments: After treatment with White Perfect D1, I used Night cream D2, for the first day, my skin a little-bit dry, but on the second day all the dead skins peel of, and my skin more smooth and soft and more hydrated.
Loved it 🙂
