fresh squeezed lemon juice for oily skin
Put cucumber in blender and puree. Put through a sieve or strainer. You should just have pure cucumber juice.
Add the same amount of witch hazel (I THINK witch hazel is ok!).
Add just a little bit of lemon juice for extra cleansing power.
This is an astringent to remove extra oil and dirt after you wash your face, or if you just got finished with some physical activity.
