However , all products are not created to perform equally . As the graph on the left shows , even products from different manufacturers containing some of the same ingredients may not perform equally well . All of the products in the below graph contain Vitamin C . Only the iS Clinical serum – in this case Pro-Heal Serum Advance + – provides superior antioxidant protection and neutralizes the largest number of free radicals . This is demonstrated by the very high oxygen radical absorptive capacity ( ORAC ) of Pro-Heal Serum Advance +.
SUNSCREENS AND POLLUTION
The World Health Organization notes that 92 % of the world ’ s urban population lives in areas with substandard air quality . 12 Pollution is also no stranger to rural environments where equipment use is important .
Combining solar UV damage with pollution multiplies the skin damage seen with each of these . 13 Including antioxidants and other actives in sunscreens is an important mitigating strategy .
Several clinical studies have now been completed that demonstrate these iS Clinical sunscreen end-products are pollution protective . These include :
• Extreme Protect SPF 30
• Extreme Protect SPF 40
• Eclipse SPF 50 +
• PerfecTint Powder SPF 40
