Using scrubs is the best remedy for oily skin and blackheads. Making a homemade scrub is very simple: mix lemon juice with a little water, three tablespoons of white sugar and a little oil. Stir well until you get a homogeneous mixture and apply it on your face with gentle, circular movements for a few minutes. Then rinse your skin with warm water and that’s it. Removing blackheads and cleansing your skin is as easy as that.
