My wife has been putting Vaseline on her hands each night for years now. I don't see any ill effects. ............... Oh well, I guess the stuff isn't too bad after all.
......what's your point?
My mother smoked for years. It wasn't until about 6 years ago she died from lung cancer that spread to her brain and liver.
What's my point? The sustained exposure to the ingredients in cigarette smoke was thought to be harmless. Since most petroleum jellies contain petroleum, hence the name, does it make sense to knowingly expose the very vulnerable and absorbent tissue known as the skin to petroleum?....especially since there are umpteen health food stores that sell safe alternatives.
Why take the chance?.........think about it.
PS- deodorant was never thought of as being dangerous. There seems to be a concern now about the aluminum chlorohydrate content and it's effects.
I don't particularly relish the thought of someday a poster on this board asking, "whatever happened to 'ol Trickpony1?", and someone responding with "....the petroleum jelly got him.".
