Some combinations for pre-shave:
All oils are Non-comedogenic
Mix equal portions of castor oil and sweet oil (a form of medical-grade olive oil available at most chain and community pharmacies).
Add a drop or two of an essential oil for some fragrance, such as lavender or eucalyptus oil.
You can substitute with Glycerine, Almond oil, Castor oil...and vitamin E.
