I use the "intensive" moisturizing lotion from CeraVe. It won't clear up the flare up but it is the best relief for deeply hydrating my skin when it's painfully dry and cracked. I also enthusiastically recommend the aveeno colloidal oatmeal bath treatment (for soaking in the tub), amazing relief!

I shared this information with another user and I will share it here as well. I have purchased A LOT of products for relief. I am going to list the products that I have tried and note my favorites. I hope that this helps!

I use the following cleansing products for both hand and body washing and all of these are awesome:
- Certaphil Flare Up Relief Body Wash
- Baby Dove Dermacare Soothing Wash
- Bath and Body Sensitive Body Wash w/Collodial Oatmeal

My favorite hand creams:
- LaRoche-Posay Ciciplast Hand Cream
- Gold Bond Eczema Relief Hand Cream with colloidal oatmeal

This is a list of my favorite body moisturizing products that I use on a rotating basis and on different parts of my body:
- CeraVe Healing Ointment (I use this above everything, note that this is the ointment, the Cerave product that comes in the dark blue container)
- Medical grade petroleum jelly
- Cortisone 10 Excema Cream
- Dove Baby Sensitive Skin Nighttime Lotion With Collodial Oatmeal
- Bath and Body Works Sensitive Skin Body Cream With Collodial Oatmeal
- Amazon Basics Eczema Soothing Moisturizing Cream
- Vanicream (this product is a bit sticky, I use this on my legs only)
- A&D medicated rash ointment w/eucalyptus (this product smells amazing and it contains vitamins A&D plus colloidal oatmeal and eucalyptus but if you are very sensitive or have allergies to fragrance you may not want to use this)
