Often used in professional spas and found in numerous beauty products, avocado oil is rich in nutrients and is beneficial to your skin. Avocado oil can be purchased in beauty shops but you can save yourself some money by making it at home. Most of the avocado's oil is in its skin and has to be extracted. To extract the oil, use an orange press.
Slide the avocado onto the blade end of a chef's knife. Push the avocado onto the blade until you feel the knife hit the seed or pit.
Roll the avocado against the chef's knife, until it's cut in half around the seed.
Remove the avocado from the knife.
Twist the avocado halves in opposite directions to separate them. One half will contain the seed.
Hold the avocado half containing the seed in one hand.
Slam the back of the chef's knife -- the side opposite the blade -- into the seed. Make sure you slam it hard enough so the knife sticks into the seed.
Twist the knife horizontally to loosen the seed. The seed should pop out. If it's stuck, pry it out with a spoon.
Scoop the meat of the avocado away from the skin using a spoon. Save the skin.
Repeat with eight to 10 avocados.
Place the avocado skins into an orange press. An orange press is used to juice oranges and it works by crushing the fruit to extract as much juice as possible. In this case, it will be extracting oil from the avocado skins.
Pull the lever of the orange press down until the mallet rests on top of the avocado skins. Once it touches the skins, pull the lever down as hard as you can to press the skins and extract the oil. The oil will drip down into the reservoir underneath the orange press which is lined with a plastic container.
Continue working the orange press until no more oil drips out from the avocado skins.
Remove the plastic container holding the oil. There may be avocado meat and bits of skin in the container.
Place a coffee filter inside of a fine-mesh strainer.
Rest the strainer across a small bowl.
Pour the extracted avocado oil through the coffee filter. The oil will drip through the coffee filter and into the bowl. As it passes through the coffee filter, any bits of avocado meat and skin will be removed.
Let the oil filter overnight before using.
