I never measure this out but I use the Jojoba oil as the base and add a few drops of all the essential oils to it.
You really could use whatever essential oils you like here. I chose these particular essential oils for anti-aging. I use a drop or two, it goes a long way, daily if not twice on clean skin. I have also mixed in my hand with a little bit of lotion to help it spread easier on elbows, neck, legs. I also love the eucalyptus and lavender oil in here for their potent smell of freshness and I somehow have good memories of these two smells.
