What's the best moisturizer for dry itchy skin all over?

Gold Bond Eczema Relief lotion. Another little trick is to mix a few drops of an unscented body oil into a glob of moisturizer in your hand and then apply. Doing so can make the moisturizer a little richer and easier to glide over the skin.

Daily flax seed oil gel caps will relieve that itching from the inside.

I Like Happy Hemp Buddha Lavender cream it Has CBD which is Healing and absorbs easily .

Sarna anti itch worked for my mom.

Everyone will have a different opinion on “best” I like Eucerin calming cream.

Eucerin eczema relief. Even if you don't have eczema, it's very rich and soothing.

If it's truly just dry skin (and not some other medical condition) my dermatologist recommends cream, not lotion. I use CeraVe body cream or Vanicream (it doesn't have lanolin in it).
