NEW YORK — The doctors are back in for the night.

Katie Rodan, M.D., and Kathy Fields, M.D., the dermatologists behind Rodan + Fields, plan to add Anti-Age Night, a two-product group, to their lineup in July.

“Our line has always been about helping real people with real skin care problems — and this line is no exception,” said Rodan. Added Fields, “This isn’t about being the cream of the moment. We’re hoping to give women freedom from foundation. We’re here to fix the flaws in their skin.”

The additions are Anti-Age PM Serum, a patented, sustained-release blend of retinol and biopeptides, selling for $75 for 60 capsules (a two-month supply), and Anti-Age PM Cream, which uses proprietary hexapeptide technology to help stimulate collagen production, at $90 for a 50-ml. jar. Both products are designed to be used with any of the brand’s skin care regimens, which include Unblemish, an antiacne line; Soothe, designed for users with sensitive skin, and Reverse, which targets fine lines and age spots.

“Skin is in major recovery mode at night,” said Rodan, citing circadian rhythms and rest factors. “After the age of 30, you lose collagen at the rate of 1 percent per year. Siegesbeckia orientalis and mimosa extract, the primary active ingredients in these products, block collagenase, which leads to the breakdown of collagen.”

The “false alarm” technology employed by the products, she added, tricks skin into thinking it is injured; the fibroblasts recognize an injury has taken place and start to produce collagen, she explained. The Rodan + Fields skin care brand is carried in about 70 department and specialty stores in the U.S., including Nordstrom and the Studio at Fred Segal. Industry sources estimated that the new products would do about $1 million at retail in their first year. The brand also plans a 30,000-unit sampling campaign.

Neither doctor would comment on pending lawsuits that involve their parent, the Estée Lauder Cos., and their former general manager, Shashi Batra. Batra, who was the general manager of Lauder’s Rodan + Fields and Darphin skin care brands, left to become president of rival brand N.V. Perricone M.D. Cosmeceuticals in March. Lauder contends that Batra is violating the terms of his non-compete agreement; Batra counters that such agreements are not enforceable in his home state of California. Both sides declined to comment, citing pending legislation.
