Maybe coconut oil would work? If you're not allergic. My roommate has a big tub of it in the kitchen (it's the consistency of butter) and small jar in the bathroom. It's good for everything from skin care to lip balm to cooking oil and spreading on toast! It's supposedly antibacterial and anti fungal, too.It is fairly hard, although I find it's still a bit softer than Calgary's, so I'm fairly used to that. Something in it lately seems to be flaring up my psoriasis pretty badly, but just on my scalp, I have a few spots elsewhere, but they are minor.
I have been dealing with other skin issues too though.
I think lemon juice would just sting, I have been using some oil.
