Use 1 to 3 times per week after cleansing and spraying on Lotion Yon-Ka. Apply a thick layer of mask to the face and neck. Leave to act for 15 minutes, keeping the mask damp with Lotion Yon-Ka, then remove with warm water. Dry without rubbing and proceed with your usual beauty treatment. To help breakouts shrink and heal quickly, apply overnight to the affected area.
