NEW YORK — Revlon Inc. is looking to recapture its glory by chasing after an underserved market: women older than 50.

As part of a turnaround effort, the New York-based cosmetic company unveiled its biggest launch in more than a decade, Vital Radiance, a line of makeup formulated for older women.

Largely forgotten as Revlon and other competitors such as L'Oreal SA have focused on age-defying beauty products for women in their 30s and 40s, the segment is becoming a hot new opportunity. Female heads of household over age 45 account for about 69.3 percent of cosmetic purchases at mass retailers, according to data supplied to Revlon by ACNielsen, a market research company.

L'Oreal, whose Age Perfect collection is aimed at the younger boomer, is slated to introduce this fall a cosmetics and skin-care collection exclusively marketed to women in their 50s and 60s. Meanwhile, Procter & Gamble Co., which has an age-defying beauty line called Cover Girl's Advanced Radiance, is studying the older market, according to Dr. Sarah Vickery, a senior scientist at P&G's cosmetics division.

Revlon is counting on the launch of Vital Radiance, along with its revamping of its Almay brand, to fuel a turnaround begun when Jack Stahl came on board as CEO and president in early 2002. He took over the reins from Jeff Nugent, who abruptly left after only two years on the job.

Under Stahl, Revlon has been on a campaign to strengthen its brands and revitalize sales of color cosmetics, like lipstick and blush, as it faced increasing competition from such rivals as L'Oreal SA's Maybelline and P&G's Cover Girl.

The company had been hurt by a large debt load since it was sold in 1985 to a subsidiary of MacAndrews & Forbes Holdings, a holding company controlled by financier Ron Perelman, who is majority shareholder and chairman of Revlon. Revlon has made major inroads in cutting its debt, most recently announcing plans to issue $185 million in stock to pay down debt.

Revlon announced in February that it was undertaking an overhaul of its business in which it will eliminate about 165 jobs — or just under 2.5 percent of its global workforce — in an effort to reduce costs.

So far, the efforts have worked. The company announced early last month that stores have allotted 23 percent more shelf space to Revlon's color cosmetics offerings this year compared to a year ago. Meanwhile, losses at the overall company continue to narrow. Last year, Revlon lost $83.7 million, or 23 cents per share, compared with a loss of $142.5 million, or 47 cents per share, in 2004. Net sales reached $1.33 billion, up from $1.29 billion in the previous year.

Revlon spent two years researching and developing the product, finding that women over 50 were having all kinds of makeup problems, from foundation being too dry and not colorful enough to eye shadow that was hard to apply to wrinkled eyelids, according to Johnson.

Vital Radiance offers more than 100 products in a hydrating formula and a special color palette — foundation is rosier than what can be found elsewhere to energize women's complexion, while eye shadow shades are more subdued tones like champagne. The packaging has bolder type to ease eye strain and more detailed application instructions than Revlon's other beauty products. The line also offers a toll-free telephone number for customers who need more personalized service. Products are priced $12 to $19, the high end of what can be found at discount chains.

Vital Radiance has gotten a strong early reception since the bulk of its products hit store shelves over the last few weeks.

"It is beating expectations," said Sarah Munson, general manager of beauty at drugstore.com. She expects plenty of other brands will follow, based on conversations with other beauty executives.
