　　In 1967, American Vogue magazine published an article called "Can Great Skin Be Created?" written by Beauty editor Carol Phillips with Dr. Norman Orentreich, discussing the significance of a skin care routine. Evelyn Lauder, daughter-in-law of Estee Lauder, read the article and brought it to Estee’s attention. Both Carol Phillips and Dr. Orentreich were recruited to help create the brand, and in August, 1968, (19) Clinique emerged as the world’s first hypo-allergenic, skin care line at Saks Fifth Avenue. Clinique tests its product for allergic reactions by applying it to 600 people 12 times, with a standard of zero reactions. There are three formulas available in North America and Europe—extra-mild, mild, and oily. Clinique also has a facial care line called CX which contains products targeted on specialized needs, such as stretch marks associated with pregnancy. Clinique also carries a skin care line targeted on men. Although mostly known as a skin care line, (20)52% of revenue for Clinique is derived from their makeup, 25% from foundation alone. Clinique also carries a line of makeup brushes coated with an antibacterial (抗细菌的) solution. Happy, Clinique’s best-selling women’s fragrance, was introduced in 1997. It features a mixture of ruby red grapefruit(葡萄柚), bergamot(香柠檬), Hawaiian wedding flower, and spring mimosa(含羞草). Recently, Clinique announced a partnership with Allergan, the maker of Botox and former partner of Elizabeth Arden, with the result being a new line called Clinique Medical. The line is only available in physician’s offices.
