Wrinkle treatment with a backbone

With all of the anti-aging, anti-wrinkle products and procedures on the market, it's hard to know where to best invest your time and money. University of Michigan researchers, who have been studying the mechanism of aging skin for a decade, say there are three treatments that really work to rejuvenate skin: (1) Topical retinoic acid, (2) CO2 laser resurfacing and (3) injections of cross-linked hyaluronic acid. All three, they report, successfully replenish collagen, leaving skin fresh and younger-looking.
