I used to apply petrolatum as well for dry skin/eczemic laesions, I agree that the heavy, greasy feel doesn’t feel nice, though it is superior in reducing TEWL.
Now I make a lighter cream for during the day (with esters like isoamyl laurate) and a buttery cream or anhydrous butter during the night (for the latter I make whipped butters, 75% shea, 22,4% oils, 2,5-5% behenyl alcohol, 0,1% tocopherol or BHT).
It’s just my opinion, but to me the whole ‘skin nurturing’ thing is just marketing BS. I’ve used creams with cholesterol/ceramides etc, but I have never noticed a significant difference.
I do however like the effect of oatmeal. It seems to calm the skin.
I agree with Microformulation: maybe it’s best to visit your GP. The addition of a class I or II corticosteroid could be an option.
