Women’s worries about wrinkles, dark spots and other aging skin concerns aren’t all vanity, a new poll reveals.

Forty-two percent of women ages 50 to 59 believe they need to look young to be successful at work, according to a recent poll by Penn Schoen Berland.

Increasingly, both men and women have anxiety about looking older, but the good news is that science has developed natural tools to help us look younger longer.

Something we all battle daily is damage from free radicals, a term that has entered the public lexicon with little understanding by most people.

Free radicals are oxygen molecules that have lost electrons through oxidation, making them unstable. If your body doesn’t have enough antioxidants to stabilize them and render them harmless, they can damage cell membranes, which eventually breaks down the proteins that support and plump the skin.

We’re bombarded by free radicals every day. We produce them when we metabolize food and even when we breathe. They’re also in the environment — diesel exhaust, air pollution, UV radiation (from the sun) and cigarette smoke are all major producers.

What’s worse, those free radical oxygen molecules are always looking to stabilize themselves by swiping electrons from stable molecules, which creates even more free radicals.

We have lots of natural defenses against free radicals, but as we age, we begin to lose them.

Some vitamins are antioxidants, meaning their molecules provide electrons that stabilize the free radicals. Clinical studies have found that certain of these are effective in preventing damage, or correcting damage such as reducing wrinkles and dark spots.

In certain cases, “taking your vitamins” means applying them on your skin so they can work from the outside-in.

Here are some thoughts:

1. Vitamin A: There is significant scientific evidence that the form of vitamin A called retinoid, when applied topically, can treat damage caused by sun exposure. It can soften fine lines and wrinkles and lighten dark spots. In one study, subjects had significantly fewer fine wrinkles after applying a prescription-strength retinoid cream (0.1 percent isotretinoin).

2. Vitamin C: Vitamin C applied topically is much more effective than taken orally. That’s because Vitamin C is relatively unstable. It quickly oxidizes when exposed to air and in certain other conditions. So, to get the full benefit for your skin, you would need it in much greater amounts than you would normally consume in a tablet. You can get that benefit by using a topical formulation. Look for “stable” Vitamin C of the L-ascorbic variety, which offers the best protection against sun damage. It reduces lines and wrinkles, protects against sun damage, and encourages production of collagen, one of the proteins susceptible to free radical damage. Importantly, collagen makes up 75 percent of our skin and gives it support and volume.

3. Vitamin B3: As a “damage corrector,” test-tube studies have shown that Vitamin B3 boosts collagen production and clinical studies have shown it reduces dark spots. In one significant study, 50 Caucasian women applied a 5 percent Vitamin B3 solution to one side of their faces every day for 12 weeks. They had a marked reduction in dark spots, redness and yellowing, and increased elasticity.

For best results, people should buy these topical vitamin products at concentrations that have proved effective — and use them for the length of time recommended.
