Wrinkles, lines, spots. Badges of our age. Most of us don't wear them with honor. Store shelves are filled with cosmetic products that claim to reduce the signs of aging, now in as little as two weeks. Well we decided to put several anti-aging face products to the test with the help of three women. Barb's in her 40's, trying out L'oreal's "Revitalift" face and neck cream. Robin is giving Lancome's "Re-surface" face and eye cream a try, she's in her 40's too. And for 30-something Ellen: Pond's "Age defying" face and eye cream. Dermatologist Paula Begoun has researched all the youth promising products. "There are a host of ingredients out there that all make claims that they're going to be the greatest," said Begoun. She and other doctors agree: one ingredient in particular does work. It is retin A. "Improves cell damage, by actually changing the cell's structure and returning it to some level of normalcy," said Begoun. Dermatologist Julie Salmon says even with the prescription drug retina A, real cell repair takes months. "When they did the studies, they're looking at the skin at about three months or six months out before you see all those nice changes in collagen," said Salmon. How did our three women do in two weeks? They all said they saw changes and so did many of their friends. Our dermatologist, however, did not find any "real" changes. "You can use products like filters or optical diffusers which change the way light reflects or comes off the skin," is how Salmon explained the improved look of the skin. She also said the moisturizers helped improve the look of the outer layers of the skin. The best thing you can do for your skin is to use a good moisturizer an gentle cleanser as well as a good sunscreen with at leat an S-P-F of 15 everyday.
