Allergan Launches PREVAGE-TM- Antioxidant Cream, the First and Only Clinically Tested Antioxidant That Corrects and Protects the Skin.

IRVINE, Calif. -- Allergan, Inc. (NYSE:AGN) today announced the launch of PREVAGE(TM) antioxidant cream, the first and only clinically tested antioxidant that not only reduces the appearance of fine lines and wrinkles, but also provides protection against environmental factors including sun damage, air pollution and cigarette smoke.(1)

Representing the next generation of antioxidants, PREVAGE(TM) antioxidant cream is a novel cosmeceutical containing 1 percent idebenone - a revolutionary, potent and effective new antioxidant.

"We had sun block in the seventies and glycolic acids in the eighties, and now we have PREVAGE(TM) antioxidant cream, the first advance we have seen in decades that is backed by scientific studies," said Jeanine B. Downie, M.D., Director of Image Dermatology, Montclair, New Jersey. "PREVAGE(TM) antioxidant cream is a potent antioxidant that is clinically proven to not only protect the skin against sun damage and the environment, but also to correct fine lines and wrinkles."

Proven Scientific Evidence

Data that compare leading antioxidants show that idebenone is the most effective topical antioxidant product available.(1) A six-week clinical study evaluated the use of PREVAGE(TM) antioxidant cream containing a 1 percent concentration of idebenone in 21 women between the ages of 18 and 65 with moderate photoaging (dry facial skin and fine lines/wrinkles). The women in the study applied PREVAGE(TM) antioxidant cream twice a day to the facial area for six weeks. Study results included:

--29 percent reduction in the appearance of fine lines and wrinkles;

--26 percent reduction in skin roughness or dryness;

--37 percent increase in skin hydration; and,

--33 percent overall global improvement in the appearance of skin.(2)

"While other creams just sit on the skin's surface, the unique formulation of PREVAGE(TM) antioxidant cream allows it to penetrate the skin at the cellular level to help prevent free radicals from breaking down the collagen and elastin in the skin," added Dr. Downie.

"PREVAGE(TM) antioxidant cream is the newest addition to our dermatology franchise," said Bob Rhatigan, Vice President, Allergan's U.S. Dermatology business unit. "With a rich heritage in skincare, we are excited to continue providing dermatologists and plastic surgeons with products supported by science and proven results."

PREVAGE(TM) antioxidant cream is available exclusively through dermatologists' and plastic surgeons' offices. To locate an office or for more information, please visit www.prevage.com.

About Idebenone

When compared to other commonly known topical antioxidants available in skincare products, idebenone is the most potent and effective antioxidant compound. Idebenone has been found to be effective in protecting the skin against key environmental stressors known to cause fine lines and wrinkles including: ultraviolet radiation, ozone, air pollution and cigarette smoke. It also was ranked the most effective compound tested in a series of biochemical and cell-biological methods used to determine the effectiveness of antioxidant compounds at preventing biological damage as a result of oxidative stress.(1)

A close relative of the compound Co-Enzyme Q10, idebenone has far greater skin penetration potential and a much higher oxidative stress protection capacity.(1) Its lower molecular weight allows for greater skin penetration and extended shelf life stability.
