As someone who gave daily lectures in my profession I always had water at hand. Do you drink at least a litre of fluid a day? If not increase your fluids, especially water. Get plenty of fats in your diet. My spouse noticed his skin improving significantly by getting a couple tablespoons of coconut oil/butter daily. Dry is absence of wet; so unless you have some rare condition, then most likely you need more liquid. I take in closer to 2 litres of liquids, mostly tea, but all liquids count. Also, after you bathe, make sure to put oil on your skin/lips to retain moisture. Vitamin E oil is very good for the lips, but you have to reapply several times during the day. Here I get it in a little roll-on bottle. Hope this helps.
This time, like all times, is a very good one, if we but know what to do with it. Ralph Waldo Emerson
