First, we want to avoid prolonged (greater than 10 minutes) showers. Avoid long baths, hot tubs. The water should be warm, NOT hot. Choose a non-detergent, gentle cleanser -- this is a crucial piece -- avoid antibacterial and deodorant soaps. Pat dry gently upon exiting the shower (do not scrub the skin). While the skin is still damp, apply a thick moisturizer.
For the cold winter months, a moisturizer should be thicker than a pump-lotion, favoring a cream in a jar. Many products contain lipids naturally found in skin which can be nourishing to particularly irritated, dry skin. If you live in a dry climate or have dry heat in the home, consider humidifying your environment.
