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].
