The Erno Laszlo Institute

Once a well-kept beauty secret of Hollywood icons, European royalty and New York society swans, Dr. Erno Laszlo’s institute reopens after a 40-year hiatus. Now anyone willing to drop $6,000 for a yearly membership (which includes facials, peels, special serums and laser treatments every three to four weeks) or $2,300 for a three-month version can be pampered like Grace Kelly, the Duchess of Windsor and Gloria Vanderbilt, who once snuck into Laszlo's exclusive facilities, then on Fifth Avenue. The glamorous tri-level spa features six private treatment rooms, a library-turned-lounge replicating Dr. Laszlo’s original 1939 study and a shop hawking the entire skin care line ($39–$325). The ground floor features a rotating art collection curated by author Patricia Eszter Margit (patriciaesztermargit.com). For a bombshell glow without the hefty price tag, pair sea mud cleansing bars ($39)—immortalized by Woody Allen in Annie Hall—with precleansing oils ($45).
