Skin care routines

How many of you guys switch up your skin routines based on the season?  I do!  I have combination skin and tend to be on the dry side.  So during winter time I need some serious moisture, especially living so far north!  I'm working on a video about my different skin care regimens during winter time.  Of course they're home made recipes that will save you tons of money!  Save that money for presents!  Stay tuned for those videos.  Make sure you're drinking enough water because not having enough contributes to dry skin conditions.  What are some things you guys do to take care of your skin?  Anything that's been working really great for you?  Anything that has failed?
