Sorry - shower creams that is
Would it be possible to consider adapting for a wet room if that would enable you to reduce transfer risk? I know people who have had adaptations where they can steer directly in, transfer to a seat and then transfer back out again - I don't know whether you use your chair fully all the time or whether you are having to navigate a standard shower cubicle - but what I have found is that having a dry towel to hand so I can ensure that the emollient is firstly liquified in the heat and then wiped off my hands/feet for when I step onto the mat/hold the rails, I don't slip.
Varicose eczema needs management to avoid it developing into ulcers - steroids can be useful for the active stage, but you can use emollient just as it is rather than crappy lotions, not just in the shower with appropriate awareness/caution about residues. It doesn't need to be put on by the gallon.
You might also need your stockings prescription updated - weight changes, for example, might mean the measurements aren't quite right for you so that the blood supply is being reduced to some parts, rather than supported, or that they aren't strong enough so it's still pooling.
BY THE WAY
I would ordinarily try to ignore the woo-woo, but seriously, @ChateauMargaux - somebody uses flammable substances daily that inherently leave a residue on the skin as their intended action (and clothing) - and your solution is to apply a source of ignition?
