Start by removing makeup and cleansing your skin with a Yon-Ka cleanser, then mist your face with Lotion Yon-Ka. 1 to 2 times per week, apply the mask generously to the face and neck. Allow to treat for 15 minutes. Note: This product can also be applied thinly as a night treatment, replacing your usual cream or serum. In this case, leave it on overnight.
