Anti-Aging Breakthrough: Vitamin A
Among the most medically studied topical antiaging treatments are the retinoids -- derivatives of vitamin A. They are offered as prescription treatments such as Retin A or Renova, but also available in weaker strengths in over-the-counter products, listed as the ingredient retinol.
Retinoids are "thought to work on aging skin by increasing collagen production and decreasing collagen breakdown," says Jamal -- and a ream of studies backs her up.
But while many doctors believed only the prescription-strength retinoids were powerful enough to cause significant change in the skin, 2007 was the year that idea changed. In a study published in the Archives of Dermatology in May, researchers from the University of Michigan found that 0.4% retinol lotion applied three times a week for 24 weeks yielded significant difference in skin wrinkling when compared with a similar lotion without retinol used on a separate group of people in the study.
Even more surprising: The average age of study participants was 87, meaning it’s truly never too late to look younger.
"For those who can’t or don’t want to have an office procedure for wrinkles, I suggest starting with retinol products, and if there are no problems, such as redness or irritation, you can work up to a prescription-strength Retin A product. But we now know that both have the power to produce measurable anti-aging results," says Goldberg.
