As my skin has aged and gotten drier I find it harder to keep it moisturized, so I use a good moisturizer, like Cerave throughout the day and use Cerave PM moisturizer at night. After shaving, I use a Vitamin C serum. This regimen works pretty well. I always wear a sunscreen when going outdoors. Some cheap ones have irritated my skin, so I use a more expensive one now, EltaMD with zinc oxide.
