I agree with Derp that it might be good to go natural, but I think a simple moisturiser will get you out of a tight spot (no pun intended ) I have dehydrated skin, and the one I linked you is really soothing. I also use the body lotion version (E45 Dermalogical Moisturising Body Lotion 200ml) as a base for my Vit B powder. THe combo makes probably the best skin care product I've ever used!
Apart from that, I just use rose water as a cleanser. It's super delicate - way better than water. Water can be drying on the skin, as you probably know.
"I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.
In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."
