Methods to enhance the back

Use back scrubber or brush, which comes with a handle in it to help you clean the back with soap.
Apply oatmeal or apricot scrubber on the back to remove black heads and white heads.
Once in a while apply sandalwood pack on the back to give it a glow.
If the back has become dark apply bleach on the back to remove the tan.
In addition to that eat healthy nutritional food and sleep properly for a healthy skin. Never go out in the sun without applying the sunscreen lotion to the exposed area.
