WHY BROAD-SPECTRUM PROTECTION MATTERS

Even such quick daily tasks as walking to your car or mailbox can initiate skin damage. Prevention requires Broad Spectrum protection from the ultraviolet B (UVB) rays that cause sunburn and the entire ultraviolet A (UVA) range. While researchers once believed only UVB rays were damaging, more and more evidence suggests protection from UVA rays is equally important. Repeated exposure to the shorter UVA II wavelength and the longer wavelength UVA I may result in excessive dryness, formation of fine lines, wrinkles, irregular skin pigmentation, weakening of the skin’s immune system and skin cancer.

HOW IS avobenzone DIFFERENT FROM CONVENTIONAL SUNSCREEN?

Avobenzone is the only ingredient combined with other traditional sunscreens to provide broad spectrum UVA I and UVA II protection. Conventional sunscreens are simply not enough. They are not designed to protect against damaging UVA I wavelengths. These products, principally formulated with UVB and UVA II filters protect against UVB and only partially protect against UVA. They provide little or no protection against UVA I ultraviolet spectrum.

ARE THERE ANY STUDIES TO SUPPORT THIS RESEARCH?

Over the last few years pioneering research work has been ongoing at the Department of Dermatology of the University of Pennsylvania using biomarkers to determine the UVA protective values of various UVA filters. In vivo studies on human skin have confirmed the benefits of the combination of the Broad Spectrum UVA filter, Parsol 1789 and other UVB filters in providing optimal protection from repetitive exposure to UV light.

The studies were conducted by Kays Kaidbey, MD Adjunct Professor of Dermatology at the University of Pennsylvania. The following changes were measured: Epidermal Thickening (associated with UVB damage), Sun Burn Cells, p53 Mutations (marker of epidermal DNA damage, Special Enzyme Deposition (the enzyme lysozyme indicates damage to skin's elastin fibers, and Dermal Inflation (indicates damage to the deeper layers of the dermis).
