.....Apply directly to the forehead.....and chin, cheeks, arms.....wherever you have skin. That's the suggestion from the results of a new study that tested the topical application of retinol, a form of vitamin A, on a group of elderly subjects.

With each subject, researchers applied retinol lotion to one arm and a lotion with no retinol to the other arm.

Roughness, wrinkles, and overall signs of aging were found to be considerably reduced among subjects in the retinol group compared to the non-retinol subjects.
