There are 2 oils that are pressed from the fruit-pulp rather than from the nut or seed:
Avocado Oil (Persea gratissima / P. americana): The fresh, oily pulp of the fruit is pressed or centrifuged to yield its oil, after which it is filtered. The oil is green due to its chlorophyll content. The freshly pressed oil degrades quickly when exposes to sunlight, making the oil turn brown – at this point it is off and should not be used. The scent is strong and fruity, when it starts to go off, the scent becomes earthy-moldy. Most avocado-oil is refined to make it more stable, it then has a light yellow color and hardly any scent. Sometimes a coloring agent is added to create the green color and raise the price. Make sure you get your oil from a reputed distributor. Store cool and dark. The oil hardens when cold but goes soft in room-temperature.
Avocado oil is rich in vitamins – especially vitamin D and E. It also contains different sterols that can have a healing effect on various skin-problems. Avocado oil is softening, protecting and cell-regenerating for the skin and absorbed rather easily. Use it on dry, damaged and mature skin.
Olive Oil (Olea europea): . When the fruits are stored free radicals are formed which impairs the quality. Therefor the fruits need to be pressed immediately after harvest. By carefully cold-pressing the whole fruit, including the skin, the extra virgin oil is obtained. Next quality-level is Virgin fine. These are the oils that should be used both for culinary and cosmetic purposes. The oil is green due to its chlorophyll content and it has a strong, characteristic scent of olives. Olive oil is stable and will keep even in room-temperature. When stored cool (10 degrees celsius or colder) the oil will go cloudy and at colder temperatures it will harden.
Olive oil is mainly used for culinary use and this is how we best receive its health benefits. Use it for cooking, on salads, bread, vegetables… A true virgin oil has a wonderful taste, I don’t use that for cooking since it destroys the scent/taste. Rather I use a lesser degree for cooking and save the glorious virgin for use on salads, bread, vegetables etc.
For cosmetic use it is a bit heavy and it has a strong scent. That said, it is anti-inflammatory and can be used for eczema, dermatitis, psoriasis, sunburn and insect-bites. Use with chapped, dry skin and brittle nails. Blend with lighter vegetable oils for skin-care.
