I find Epsom to be the least drying. It's not even technically a salt, it's just called that because of its appearance, I learned.
If I use Epsom, it has to be in a product, or if I do a spray, I have to mix LI and oil in there to help balance the drying effects.
Some people use magnesium oil (mag chloride), and say it's less drying than Epsom, even.
