Well Scarlett and I are unable to get any of that anywhere here in the U.K. Hunting for any lizard is forbidden and the size of them would not bear much oil at all.
Open water swimmers here use something called channel grease. In days gone by that was goose fat or lard. These days it is a kind of vaseline/lanolin mix. More used for insulation and anti chafing properties. I am not sure what it does for the skin but they look like bleached prunes when they get out of the water.
I will use my trusty Nivea cream as my mother did and seemed to work for her, although, at 94 her skin is a little prunish……..
