Salt scrub or sugar scrub will do the job, (as usual product) you'll get better result if you use it when your skin is DRY, not wet. So strip down and use the body scrub before you get in the shower. Rub it all over you body to strip off the rough skin. Rinse it off in the shower and feel how smooth and soft you skin is. Afterwards, pat your skin with dry towel and lotion up.
Goodbye dry skin! :)
