Beard Oil Issues

Hello!

I have a question for everyone concerning beard oil: How essential is it?

The reason for my question is this:

I have a history of grand mal seizures and while that has been under control for a long time via medicine, occasionally something that would trigger a full on seizure will cause me to have little tremors. When this happens, it's an indicator to stop doing that thing to avoid the potential of full seizures.

Well, I found out yesterday that something in the beard oil I'm using is causing me to have those tremors and of course this means I can't use the product anymore. Now, it's very likely that it could be specific to this particular scent but I'm a bit leery of trying other beard oils for obvious reasons. I don't seem to have this issue with beard balms.

I've had a beard for a very long time but for the most part I've kept it very short to make it easier to maintain. But now that I'm thinking about growing it out more, I'd like to know how mandatory beard oil is for maintaining skin health since I can't use it (or if someone has other suggestions I'm open to that as well). If it IS mandatory, I may have to just continue with keeping a short beard.
