There is a woman whose name is only whispered in certain circles. She is Tracie Martyn, the facialist regarded as a savior throughout New York for her dramatic face-depuffing capabilities, Elizabeth Hurley, Madonna, and Linda Evangelista are all devoted fans. Fashion photographer Steven Meisel regularly sends top-ranking supermodel types to Martyn's lower Fifth Avenue spa for pre-photo shoot tune-ups. In addition to her Resculpting techniques (Martyn has developed a way to manually strengthen facial muscles, which she combines with lymphatic drainage,), the secret to her stunning success may be attributed to her private-label Firming Serum, a complexion-lifting, fine-line-reducing cocktail of powerful antioxidants (red-wine-derived resveratrol and Chilean evergreen extract, an anti-inflammatory, among others) and epidermal-growth factors, which help increase collagen and elastin production. Susan Sarandon carries a bottle in her purse; Liv Tyler begged for a preproduction sample in a Ziploc bag (and was denied!); Gwyneth Paltrow bought a bottle as a gift for Kate Capshaw-who, unbeknownst to her, already had a private stash. This month, Martyn's magic potion becomes available to the masses: (866) T-Martyn.
