I moisturize every night, been doing it for over a year. Amazon sells this Oil of Olay Regenerist stuff on subscription for $15 (about $5 cheaper than you can find in the real world) so I just get that every couple of months. Consumer Reports ranked it highly compared to the really expensive stuff, and my face definitely used to get dry in the winter. No more, I use it at night and my face is usually really soft in the morning.
