In addition, fat pads under the skin begin to disappear; wrinkles and skin sagging appear. Aging can be accelerated due to the harmful effects of the sun, cigarette smoke or abrasive chemicals. There are now many good and proven options available for those who wish to overcome some signs of aging, including some medications.
