Supplements for Skin Protection

UV Blocking Agents
One of the oldest topical skin protectants is zinc oxide. Most of us remember seeing kids on the beach, their noses painted bright white to protect them from the sun. Now the stuff comes in an assortment of pastel colors, and it remains an excellent physical barrier to UV light penetration.

Now there are two other products that protect from the sun, but without the distracting colors. Micro-fine zinc oxide and micro-fine titanium dioxide both offer a high level of protection against UVA and UVB penetration.

Sunblocks containing octinoxate and oxybenzone are also exceptionally strong. All of these products protect the skin’s DNA.

Topical Green Tea Extract
This product has been shown to help thicken the skin by stimulating keratinocytes — special cells that make up the outer protective layers of skin. And one keratinocyte component — in addition, one component epigallocatechin gallate(EGCG) — provides powerful protection against UV-induced DNA damage.

Silibinin and Silymarin
These are special flavonoids found in the milk thistle plant. When applied topically, they have been shown to prevent cancer formation in the skin of mice exposed to carcinogens such as chemicals and UV light. Combination with the green tea flavonoid EGCG brought about powerful anticancer effects.

Grape Seed Polyphenols and Other Grape Products
Grape seed contains flavonoids called proanthrocyanidins, which powerfully inhibit skin cancer caused by UV light exposure.

Its antioxidant effects are 20 times more potent than those of vitamin E and 50 times stronger than vitamin C. And when taken by mouth, grape seed flavonoids protect elastin and collagen from UVlight damage.

Another grape product called resveratrol also protects skin from UV damage. In fact, it appears to play a role in protecting grapes from sun damage.

Turmeric (Curcumin)

The spice turmeric contains the flavonoid curcumin — a very powerful anti-inflammatory agent and cancer fighter that also protects the skinfrom UV damage when applied topically.

Normally, turmeric and curcumin are a deep yellow and can be quite messy to use, staining everything they touch. A newly developed form, tetrahydrocurcumin, is colorless but retains all of its beneficial properties. It has also been shown to lighten blemished skin and may inhibit melanoma growth.

Rosemary Extract
Rosemary contains two antioxidants, carnosic acid and ursolic acid, both of which offer effectiveskin protection. In animal tests, when a carcinogenic chemical was painted on the skin, rosemary caused a 99 percent reduction in tumor induction.
