Long, hot showers can help clear your stuffed-up head, but they dry your skin. So keep them short -- no more than 5-10 minutes. Use warm water, not hot. And only take a shower or bath once a day.
Skip the soap. "The purpose of soap is to cut grease. The greasy, oily layer on top of our skin keeps the water underneath it in and keeps our skin hydrated," says Karthik Krishnamurthy, DO, director of the Cosmetic Dermatology Clinic at Montefiore Medical Center in New York. "Soap strips away that oily layer. The important thing is to get water back in our skin and get a greasy layer back on."
Use a gentle non-soap cleanser on your face and body, instead. Don't use antibacterial or perfumed soap, deodorant bars, exfoliating cleansers, or any skin care products that have alcohol, like many hand sanitizers. Use things that are fragrance-free. They're less likely to irritate and dry your skin.
After your shower or bath, slather on moisturizer right away -- ideally while your skin is still soaking wet, Krishnamurthy says.
"Leave your moisturizer on the shower shelf with your soap and shampoo," she says. "Don’t even step out of the shower. Put it on while you're dripping wet, then pat yourself dry."
Thick, heavy creams last longer than light lotions. The thicker and greasier it is, the more it will trap and hold the water in your skin. Look for ingredients like ceramides that are like skin's natural fat. But simple petroleum jelly, mineral oil, shea butter, and glycerin work well, too.
Moisturize throughout the day. Since you'll be washing your hands often to avoid spreading germs, keep lotion by the sink so you can nourish your skin every time you wash up.
If you feel itchy or uncomfortable throughout the day -- especially on your hands, arms, and legs -- then moisturize. Reapply before you go to bed.
