I use organic grape seed oil. "Naissance" off amazon. I seem to get through 1 litre every 6 months, costs me around £1.30 a month.
Coconut oil (fractionated), also from Naissance. 5L (£60) every 6 months.
Zero fragrance whatsoever, all good.
But, have to say, that after using it so often, I developed dry skin and spots on the chest area.
Now I'm moisturising with Body Shop body butters before every booking and my skin is back to normal.
I'm not entirely sure but think that the refined form of oil is stripped of all the natural 'goodies', hence the drying property (in the long term).
