Your diet alone is not going to erase your wrinkles or completely put the brakes on the aging of your skin. However, the old adage “you are what you eat” does apply, since your diet affects every organ in your body and the skin is one of them. Every cell in your body needs nutrients and metabolites, some of which come must come from food—not even the best skin care products can completely replace them. When you take in food, its nutrients enter your bloodstream and delivery to the skin cells is unavoidable. Good nutrition can slow the overall aging process, and nutrients and foods that benefit your skin also tend to improve your overall health. Nutrients from topical skin cream will not magically penetrate your skin cells because the skin cream has been applied—the condition of your skin, the concentration of the skin cream’s ingredients, applicable manufacturing processes, and many other factors will determine the reliability of your skin cream’s effectiveness on the aging of your skin. Skin aging combines the innate mechanisms of human physiological aging with environmental damage. Limiting sun exposure and the use of sunblocks are absolutely necessary to affect this aspect of skin aging. Nutritional supplements in pill form have proven ineffective thus far in the prevention of skin aging, their effects ranging from ineffective to unsafe.
In short, a balanced diet is important to promote and maintain skin health. It may not provide skin rejuvenation on its own, but neglecting your diet will accelerate the skin’s natural aging process. Certain vitamin and nutrient deficiencies can cause negative skin conditions such as dermatitis. Mild deficiencies commonly go unnoticed, but can impair the skin’s ability to renew and heal itself. Some nutrients taken in higher doses than the recommended daily requirement, but remaining in the safe range, may produce skin benefits beyond that of basic balanced nutrition.
