The skin provides a natural barrier between the outside world and the inside environment.
Skin rejuvenation involves providing a combination of nutrients to aid the skin in growing and specific antioxidants to protect the skin from damage.
The rays of the sun cause melanocytes to produce melanin, the pigment that causes skin to darken.
This is the body's natural defense against the sun.
Sun exposure is also the primary method of vitamin D production.
Fair skinned individuals on the other hand, don't produce enough pigment so their natural defense against ionizing radiation is less.
They also stress-out their skin when they sun bathe.
Skin is also stressed-out by internal toxins when it is used as method of detoxification.
While this is a natural function of the skin, toxins may become lodged in it, causing the skin to become irritated and dry.
The most important factor in protecting the skin from chemical, sun-related and toxic stress is through the body's antioxidant systems. Antioxidants are needed to quench or neutralize free radicals. Free radicals are generated by the aforementioned stresses.
Powerful antioxidants are needed that to deactivate a specific type of free radical known as singlet oxygen, the one that is generated by ionizing radiation.
The best antioxidants to accomplish that are described below. These are the real skin-rejuvenators.
Lycopene, the antioxidant in tomatoes is known to repress cancer formation, aid the eye and protect the skin.
Green Tea Polyphenols neutralize free radicals, prevent chemicals from binding to skin and allow water to bind to collagen.
Grape seed extract contains powerful antioxidants, including pycnogenol.
Grape seeds are an excellent source of proanthocyanidins, a flavenoid that protects capillary walls.
Proanthocyanidins also inhibits the enzymes that break down collagen and elastin.
Grape seed antioxidants protect melanocytes from free radical damage.
Grape seed antioxidants have a very strong affinity for collagen allowing them to attach themselves to weak collagen to strengthen it and maintain its moisture content.
Garlic is king of the preventive foods due to the presence of sulfur. As such it must be considered a skin-rejuvenator
Sulfur is found in the proteins that form skin, hair, and nails. It is also an integral part of collagen and is needed for the synthesis of connective tissue. Garlic can thus enhance the strength of the disulfide bonds that hold collagen strands together, the so-called cross-linking phenomena.
MSM is another product that boosts the sulfur content of the diet. This may be used by those not wanting the odor of garlic.
Glucosamine, a major component of an anti-arthritis formula, is also a key skin-rejuvenator. Glucosamine is the nutrient that forms dermatan sulfates, the primary structural matrix of skin.
Hyaluronic Acid is another product used to combat arthritis and is also important as a skin-rejuvenator. HA retains a thousand times its weight in water and holds four times the moisture as collagen.
