No worries.
I tried all ingredients individualy to see if they suited my skin and to be honest all would be more than fine by themselves.
As said only use a tiny amount warmed in your hands because too much will not be absorbed quickly.
This is free from chemical preservatives so store away from sunlight. Vitamin E is a natural preservative but it won't last forever, 18-24 months is a resonable shelf life to expect.

Have fun with the essential oil, my favourites are lavender, lime and a mix of cypress, bergamot and lavender.
