Nouvelle Beaute Serum To combat dry skin on the legs, you ought to steer clear of germicidal cleansers, hard scrubs and very hot water. Soaps of a germicidal nature tend to remove an abundance of the natural oil found in skin. Scrubbing with too much force and using extremely hot water causes damage to your skin's protective layer. Use gentle rubbing with beauty soap and warm water to ensure your legs don't dry out.
