You can up the superfat, use some butters or avocado oil, refrain from using artificial fragrances (you will need to if your skin is anything like mine), whatever you do, you can only make a soap that is not drying to skin but not something that is moisturising. Especially if everything else like the dry weather, hot air from furnaces in the winter, pollution, your own sensitivities so on and so forth is drying to your skin, a non drying soap is just not enough. I love body butters for my own skin in the winter.
