Add about a tablespoon of white sugar to your regular cleanser to make it a scrub. When using a foaming cleanser; apply the foam to your face and then mix the sugar with the remaining cleanser left on your hands then apply to your face.
The sugar dissolves, in a couple of minutes, with the cleanser and water so it wont irritate skin. Also sprinkle sugar on bar soap for a similar effect. Use your cleanser as normal and simply rinse with water and your skin will be softer and smoother.
If your skin is oily you can do this every day or for sensitive skin once a week should work.
