A number of contributing factors can act as causes of dry skin. They include:
Dehydration : This can happen when you are either not drinking enough water or consuming too many sugary, caffeinated products, such as coffee or soda.
Allergens : If you are prone to allergies, certain times of the year can cause your skin to be dry and tight. Allergy medications can contribute to dry skin as well.
Weather : Cold weather dries out skin, making it uncomfortable and sometimes cracked. This is the most important time of the year to make sure you are using a good, deep moisturizing lotion on your face and body.
Irritants : These can include perfumes, laundry detergent and chemicals in your beauty and skin care products that irritate the skin and cause overall dryness.
