I haven't tried it but Arden's co-partner in manufacturing, Allergan, is a long-standing pharmaceutical brand here in the states. I'm curious about the antioxidant but the price makes me go "eeeep!". ($150 for 1.7oz)
Here's some product information to save from digging though websites:
Anti-Aging Treatment
This revolutionary new skin care technology alters the chain reaction that can result in visible signs of aging. Created by a team of dermatological scientists and cosmetic chemists, the exclusive Prevage formula contains Idebenone, the most powerful antioxidant for correcting and preventing degenerative cellular damage caused by environmental assaults. Clinical tests show a significant decrease in the appearance of fine and wrinkles and an improvement in the look of firmness, tone, texture and radiance. 81% of consumers tested, including those with moderate to severe sun damage, saw a significant improvement in their skin's overall appearance.
In an 8-week clinical study, Prevage anti-aging treatment with Idebenone achieved the following results:
36% improvement in the appearance of fine lines and wrinkles
47% improvement in skin tone
55% improvement in the overall appearance of photo-damaged skin
63% improvement in the look of skin's firmness/elasticity
77% improvement in the appearance of rough/dry skin
Prevage also contains Green Tea extract, another powerful antioxidant. In addition, advanced skin brightening technology helps to even out skin tone and minimize the appearance of discolorations and dark spots. An advanced polymer complex helps restore skin's natural protective capabilities.
