If you really want to fight aging like Captain America, don't worry yourself with moisturizer. Instead, try to get some of that awesome super soldier serum the government uses on Steve Rogers.
Oddly, Marvel and Kiehls thought Captain America would be a perfect spokesman for their new line of "heavy lifting" anti-aging products for men. Maybe it's just me, but I see Tony Stark as a much better spokesperson as he actually is concerned with his looks and does age at a normal pace.
