The one thing that you need to be careful of is the strength of the essential oil dilution for your beard oil. For healthy adults you can use up to 2% of essential oil to base oil for regular use, although if you have sensitive skin or intend to use it daily it may be better to go for 1%. 3%+ dilution is only for short term and acute use, and should not be used regularly or long term.
