The key to healthy skin lies beyond which soap you use. It depends on what you eat, whether you exercise, how much stress you're under and even the kind of environment in which you live and work.
All of these things affect how fast your skin ages, and thus how it will look, by influencing certain processes that lead to oxidation and inflammation. Sounds complicated, but it really is not.
Basically, complex chemical processes in your body produce unstable molecules called free radicals. Think of them as Skin Enemy No. 1. Left to their own devices, they go on to damage otherwise healthy cells in a process called oxidation. This is the same process that turns an apple brown or changes a copper roof from reddish gold to blue-green, so you can just imagine the way it can affect your skin. Sun, smoking, air pollution and poor diet all speed production of these free radicals.
Luckily, your body also produces antioxidants, molecules whose job it is to sweep up those free radicals before they can do any serious harm. How you take care of yourself—including what you eat—can increase production of these valuable molecules, literally saving your skin.
Nutrition and your skin
Women have been using foods as facial treatments for centuries, making masks of egg whites and olive oil, putting cucumbers over their eyes to reduce swelling. But did you know that the food you put in your mouth can affect the health of your skin more than anything you could put on your face?
Although studies find certain individual foods can help you maintain healthy skin, your overall diet—as well as your weight—matters most. For instance, if you're overweight and/or you eat a diet high in processed foods, including white bread, cookies, ice cream and packaged dinners, and low in fiber and fresh fruits and vegetables, you have a higher risk of developing a condition called insulin resistance, which can lead to diabetes.
In this condition, insulin, a hormone that "unlocks" the cell so glucose, or fuel, can get in, doesn't work very well. Thus, all this glucose builds up in your bloodstream instead of disappearing into cells where it's supposed to go. This, in turn, damages skin. How? By reacting with the protein fiber network (i.e., collagen and other proteins) that make skin resilient. This reaction creates harmful waste products called advanced glycosylation endproducts, or AGEs, those free radicals mentioned earlier. Fibers stiffen, skin loses it elasticity and you become more vulnerable to wrinkling, sagging and damage from ultraviolet (UV) light.
