Re: Long term steroid use
Pros: While studies have found that petroleum jelly doesn't have an actual healing effect, it does create a seal on your skin, preventing air from drying it out and protecting it from the elements.
Cons: Petroleum jelly is made from just that—petroleum, a nonrenewable resource that may be contaminated with cancer-causing agents called polycyclic aromatic hydrocarbons. Furthermore, ingesting too much of it (which is easy to do when you slather it on your lips in winter) can lead to upset stomachs and diarrhea.

Pros: Beeswax works like petrolatum by creating a seal on your lips that protects them from air and other elements that can dry them out. Plus, it's made by bees, so there's no worry about depleting nonrenewable resources and there are no adverse health effects associated with licking too much beeswax off your lips.
Cons: If the current decline of honeybees continues, beeswax-based lip balms may not be around for us to enjoy forever. Plus, the cost of the ingredient tends to raise the price of the lip treatment.
