Hada Labo Shirojyun clear lotion should be used after washing and serves as the foundation to your skin care routine. It helps prepare your skin for better absorption of other Hada Labo brightening products. Simply warm a small amount between the palms of your hands, then gently pat it onto your face for deep moisturization. This is the Hada Labo patting technique. Follow it with Hada Labo Shirojyun milk or other Hada Labo Shirojyun moisturizing products.
