• Be sure to drink at least eight eight-ounce mL glasses of water each day. Herbal teas and juices also count.
• At least twice a week, eat some oily, cold-water fish like herring or salmon. These are rich in omega-3 fatty acids, which help keep your skin-cell membranes healthy. Other good sources of these fatty acids are walnuts, avocados and flaxseed oil. Mix up to two tablespoons of flaxseed oil each day into your salad dressing or your morning oatmeal. (If you add it to hot cereal, do so only after the cereal is cooked. Flaxseed oil breaks down into less-useful compounds if you cook with it.)
