2. Stay Hydrated, Inside and Out
When you’re sick, you’re usually a little dehydrated, too—which can show on your skin. This is the time to slather on an intense facial moisturizer both in the morning and at night to prevent a parched look. Bonus: You’ll protect your skin against all that nose-blowing friction, too. And tuck a small bottle or tube of heavy-duty moisturizer in your handbag (along with a personal pack of tissues) before you head out for the day.
