Unfortunately, there may not be much you can do; a study from Denmark showed that skin wrinkling with aging is influenced heavily by genetic factors (Age and Aging, January 2006). However, this does not mean that you can smoke or spend many hours in the sun, two behaviors that are known to increase wrinkling.
The authors studied twins to show that skin aging is associated with both genetic and environmental factors. They also found that looking older with severely wrinkled skin is associated with dying earlier. You increase your chances of having aged, wrinkled skin by smoking, exposing your skin frequently to sunlight or being very thin.
