Smooth skin can be easily achieved by using some sea salt and may be natural loofah. Buy some sea salt, for example Al-Zara. Dissolve about a handful of the salt in a litre of warm water. Soak the loofah in the solution and scrub your body with it until you have used all the solution. Just rinse with a little shower, don't use anymore shower cream. If you want to, use it before you use the salt solution.
