Oooh. Tree oil sounds good. Sin - I have a question about the piercings - sorry it's off subject. I hope you don't mind.
Anyway, when you got your nipples pierced, did it change the shape of them? You know when your nipples arent hard, they are soft. . . so with the rings or bars in, were they always hard?
I don't mean to be so off subject, I was just thinking of having it done.
As far as the dyrness, something I use if I have a 'dry' prob is bag balm. You can find it in any drug store. I know it's kind of strange to think of using something on your body that farmers use on cows boobies, but it works!!
Comes in a green square tin, red writing on the outside of the tin.
Even if it's not dryness, bag balm would be good as far as a preventative measure ensuring that the cracks will stay away!!
