You have to read the ingredients. The stuff from Walmart (and MANY other lotions) contain alcohol. Look for "alcohol" or "isopropyl" on the ingredients on the back of the bottle. That pink stuff burns if you have a rash or burning eczema.
Alcohol isn't a problem if your skin is just dry, so it's good to keep eczema away, but is NOT GOOD if you already have a rash or that crinkly painful eczema skin condition. For that I use Gold Bond Eczema Relief, it's in a big bright orange tube. It contains "colloidal oatmeal" - not the stuff for breakfast but basically gentle, hydrating, and doesn't dry up fast.
I was just looking back at my prior post and I wasn't being clear at all - don't use the pink lotion to treat eczema if it's hurting. ONLY if the skin is still fairly healthy. The gold bond also tends to dissolve leak guard adhesives too, so interestingly enough XP Medical's A+ diapers (no longer sold) worked really well with it because they don't have leak guards.
