Hollywood kept this firm's products hush-hush for more than 10 years, but in 2003 creator Yong Lee and makeup artist Ilona Herman teamed up to bring these coveted products to the public. Protective Nourishment, a skin care manufacturer, supplies cleansers, toners, serums, creams, and other cosmetics to Beverly Hills elite and movie stars the likes of Uma Thurman, Sean Connery, and Robert De Niro. Products are sold in salons in California, New Jersey, New York, and Pennsylvania, as well as in Canada, Germany, Korea, and through the company's Web site.
