Reducing Sunburn Damage
New study by German doctors is a first for humans
from LaCrista News, Vol.5 , Issue 4

Use of combined vitamins C & E can reduce sunburn reaction, according to a new study by doctors in Munich, Germany, which has been published by the American Academy of Dermatology.

When test subjects took vitamin E without Vitamin C, or took a vitamin complex that contained vitamin E but not vitamin C, no significant changes were found, according to their study. "Systemic vitamin C alone has been regarded as having 'poor and questionable' effectiveness in preventing sunburn."

But when test subjects, 4 women and 6 men, were given combined vitamins C (2000mg) and E (1000iu) daily during 8 days of treatment, their skin
reactions to sunburns were reduced.

Cancer-Causing Compounds In Sun Creams?

A chemical once common in sunscreens may cause premature aging and skin
cancer In the 1950's, trans-urocanic acid (t-UA), a compound found in human skin, was hailed as a 'natural sunscreen' and added to dozens of sun protection creams and lotions. Now scientists say the chemical, which absorbs UVB light, could largely be to blame for leathery, wrinkled and sun-damaged skin.

The discovery was made by Dr. John Simon and Dr. Kerry Hanson at the University of California in San Diego. "We studied a natural component of human skin exposed to ultraviolet light and uncovered a new chemical reaction that may contribute to aging of the skin and cancer," Dr. Simon reports in the latest edition of the journal Proceedings of the National Academy of Scientists.

About 90% of the visible signs of aging, such as deep wrinkles, thickened skin and age spots, are believed to be caused by ultraviolet rays (UVA and UVB) from the sun. Thirty years ago is was assumed the chemical t-UA would protect skin from the sun since it absorbed UVB light.

But this study found that when UVA light in a particular wavelength range strikes the molecule, it sparks the creation of destructive oxygen-free radicals. These rogue oxygen atoms are linked with premature aging and are also believed to weaken the immune system and damage DNA, possibly helping to trigger cancer.
