Hi B.---Good answers so far. I'd like to add that the first place to start caring for your skin, besides drinking lots of water, is your diet.
Think of it, your body makes new skin cells all of the time. We have to give our bodies good building blocks in order to make the healthiest cells possible. I am taking a series of classes taught by a Naturopath who has her PhD in Nutrition. Dr. Pam teaches that an optimal diet is one that consists primarily of plants. 90% of our calories should come from plants, fruits, veggies, whole grains, beans/legumes, nuts and seeds. Minimize animal protein as it contains mostly saturated fat and calories, with no fiber or nutrients needed to keep us healthy. I recommend reading The China Study by T Colin Campbell to learn more. We should be eating 7-13 servings of fruits and veg each day. So it takes some planning to get all of that in. When you eat this way, you reduce your risk of all diseases as well. IF you can't, won't or don't eat enough fruit and veg (and we likely need to eat more bc our food is not as nutritious as it once was), feel free to contact me and I can help with recipes and other ideas that help to concentrate plant based foods into your meals.
Get plenty of sleep, reduce stress, exercise and you will help your body make healthy skin cells. That, along with proper cleansing and moisturizing, and you will optimize what your genes have given you. I also work with a biochemist who has written a book called Do You Have the Guts to be Beautiful, http://www.amazon.com/Do-You-Have-Guts-Beautiful/dp/09714.... Her name is Mitra Ray, PhD.
Hope this helps. Good luck and I look forward to helping more if you'd like. Be well, D.
