I have horribly dry skin. I first started using Urgent Moisture by Origins back in 1999 and it worked miracles. Now I switch between that and Shu Uemura deepsea therapy, which is also great. I use Cetaphil in the tub for body lotion in the winter. It does wonders and even keeps my feet soft during these long, dry, cold months.
On really dry skin days, like if we've had extreme temperature changes, I use an Origins mask called Drink Up. It smells citrus-y and does the trick.
