Milk is a great oil-free cleanser that can make oily skin soft and supple. Milk has alpha hydroxy acids that gently exfoliate the skin and also help maintain the skins natural pH balance. Mix two or three drops of sandalwood or lavender oil with two tablespoons of milk. Apply the mixture on your face using a cotton ball. Gently massage the skin for a few minutes to improve blood circulation and then go to sleep. In the morning, wash your face with cold water. Do this daily.
