People with greasy nose and large pubescent pores should massage their noses with their fingers first applied with vegetable oil and often with salt. People with tender or dark skin should often massage their skin with a nutritious cream and a little salt to get nice skin.
The elbow or knee callus can also be removed in this way. And when you have a blotchy complexion unduly often, you wash it with salt to remove the blotches and to get smooth skin.
