Focusing on the vicious circle of melanin generation and skin problems, Perfective White XX is formulated with two active ingredients: kojic acid and allantoin, a new active ingredient that treats rough skin. 

The serum tackles the cause of deep-rooted, stubborn blemishes that grow bigger and darker even with UV protection, and inhibits melanocytes from producing excessive melanin. The result is even-toned, highly translucent skin.
