Hi Izzig
I use Macadamia oil but only on myself. The reason I use it is because I have dry skin - it is rich in palmitoleic acid (the essential fatty acid found in sebum).
Unrefined Macadamia oil has a fine texture, has a golden hue and has very little aroma - so I sometimes make up 10ml and add 4/5 drops of my fave oils - depending on how I'm feeling but usually sandalwood, rose, lavender and frankincense.
I had a look in one of my books and:
For dry skin conditions, it suggests:
15 ml Macadamia oil
10 ml Extra Virgin Olive Oil
3 drops of sandalwood
1 drop of rose otto
For ageing skin:
10ml Macadamia oil
15ml Apricot kernel oil
2 drops neroli
1 drop myrrh
1 drop geranium
The oil I have is from Aus but I will be looking for a supplier closer to home for a replacement - not all suppliers have it.
Obviously, as with all nut products, check before using it!!!!
Hope that's of some use.
