Gave up using Barrier Cream, (not that it was not effective) but it it gripped any non rotating handle or socket extension, so that it rubbed the skin.
Often wear industrial gloves, but they are not waterproof, (so your hands can become soiled with dirt carried through in the oil/coolant) and eventually become soft and start to sag or get trapped between the workpiece and the jaw as the vice is tightened.
Washing Up Liquid is good, (with or without sugar/sawdust – never tried salt. NOT if you have a cut!) but dries out my skin, and having had Dermatitis, try to avoid using it. Still using original green Swarfega, IMO, better than the more expensive Orange version.
