Carrier oils have the potential to be one of the most sustainable skincare ingredients available to us when farmed and harvested responsibly.
But we can go even beyond sustainability to the idea of zero waste and upcycled ingredients.
The juice and food industries use large amounts of fruits and berries to make juices, jams, canned fruit and all the other prepared foods on the grocery store shelves.
When the fruits and berries are processed, a large amount of seeds are left behind.
And all these seeds can be pressed for their anti-oxidant rich oils trapped inside.
Oils like strawberry seed oil, kiwi seed oil, fig seed oil and raspberry seed oil would be unattainable if not for resourceful people sourcing, separating and pressing these discarded seeds.
Kiwi seeds are tiny, and it takes A LOT of seeds to make a small amount of oil. But when the seeds would otherwise be thrown away, suddenly kiwi seed oil becomes accessible and sustainable.
Upcycled ingredients, zero waste and sustainability are increasingly becoming part of the conversation around skincare and formulating.
Here are 20 carrier oils you can find pressed from from seeds discarded by the food industries.

In theory, any food products where seeds are removed and discarded has the potential to fall into this category of upcycled skincare oils .
Many, if not most of the carrier oils and lipid plant oils are sustainable when sourced and grown responsibly, even if they do not fall into the upcycled, zero waste category here.
Most of the grain oils would fall into this category, fruit trees that produce abundant harvest like olive, avocado, pistachio, coconut, mango and so many more.
Sourcing and sustainability is important, and getting to know your suppliers is key to forming trusting, lasting relationships that support people and the environment.
