ABSTRACT
The presence of ultraviolet (UV) lters in skin care and cosmetic products represents a key benet that cosmetics can provide consumers. The hazards of UV light exposure are well known. The incidence of skin cancer is increasing at an alarming rate. More than 2 million people in the United States are developing over 3.5 million skin cancers every year [1]. UV-induced damage or photoaging accounts for most of the age-associated changes in skin appearance [2]. UV radiation damages the skin by both direct effects on DNA and indirectly on the skin’s immune system [3].
