These new potions are primed to rejuvenate your skin. Queue up at beauty counters this month when La Mer — a cult favorite slathered on by celebrities and those in the know — introduces the Regenerating Serum ($250, at Neiman Marcus, Saks Fifth Avenue). This anti-aging powerhouse is infused with La Mer’s proprietary Miracle Broth, as well as the company’s new Regenerating Ferment, a derivative of marine plant stem cells. Dr. Max Huber created La Mer more than a decade — and 6,000 lab experiments — ago to heal scars he suffered after a lab accident. Ever since, ardent followers have trusted his creams to stave off the signs of rapid aging. Meanwhile, fans of Chanel’s anti-aging Sublimage line will want to indulge in the new Sublimage Essential Regenerating Fluid ($295, at Chanel stores and counters). This weightless, silken lotion disappears into one’s skin to create a matte finish, pinpointing wrinkles, evening out the complexion and producing a radiant glow. What girl doesn’t crave that?
