The short answer is that context and processing matter in the question of "are all seed oils bad for you?"
The main reasons people avoid seed oils are concerns around the high heat industrial processing that strips nutrients and antioxidants from the oils and leaves them more prone to oxidation, plus a higher ratio of omega 6's vs. omega 3's.Â
And we get it! ...we also avoid consuming seed oils in our diet and have done for the last 12+ years.
But the seed oils used in cosmetics are different to the industrialised seed oils that are mass produced for the food industry - so you can’t tar them with the same brush.Â
The seed oils used in cosmetics and in our creams are typically organic and cold pressed, so they’re not subjected to the same high heat, solvent extraction as mass produced seed oils for the food industry.Â
One critical outcome of this difference in processing is that cold-pressed and CO2 extracted seed oils retain all of their vitamins and antioxidants that normally get stripped out with industrialised processing. Â
Sunflower is naturally high in Vitamin E and cold pressed sunflower oil contains relatively high amounts of Vitamin E which helps to prevent oxidation of the more fragile elements in cold-pressed sunflower oil.Â
(and of course one of the major concerns with industrialised seed oils is around oxidation of the omega 6's - a very real concern when this Vitamin E is stripped out - but not as much of a concern with cold pressed seed oils that retain their natural antioxidants)Â
And the Rosehip Seed Extract we've chosen for these Dream Creams is extracted using supercritical volcanically sourced CO2. This is a step up from cold pressing as it ensures a more stable end product and more bioactive components are present - including carotenoids and other antioxidants.
This context and processing matters.
I would definitely avoid putting highly processed, industrialised seed oils on my skin, but cold pressed seed oils are beneficial for skin when balanced with healthy fats, lipids and other fatty acids.
Â
Here's why - Omega 6's are actually critical for our skin health (especially linoleic acid and gamma linoleic acid)Â
Without linoleic acid our skin would become thick, scaly, rash and our skin barrier function would be seriously compromised. Omega 6's make up an essential part of ceramides - one of the 3 main components of a healthy skin barrier alongside fatty acids and cholesterol.
Â
And it's always important to remember the balance - omega 6's are only bad when they are extremely overbalancing omega 3's.
Omega 3's, 6's and 9's should not be avoided on the skin as they are all critical for healthy skin, especially in conjunction with the other fatty acids and cholesterol found in grass-fed tallow.Â
Â
On the sunflower oil we use in our Soothing Baby Cream - we use a high oleic acid type of organic cold pressed sunflower oil in our Soothing Baby Cream (this is more commonly used in cosmetics as it's more stable) and the fatty acid profile reads like this: oleic acid 84%, stearic acid 2%, palmitic acid 4% and linoleic acid 7%Â
Â
...so the amount of omega 6's in this sunflower oil is much lower than that found in mass produced seed oils for the food industry.
In addition to all of this - when we apply products containing omega 6's on our skin, they're not going through first pass metabolism in the liver and being turned into the more inflammatory arachidonic acid. Â Â
And lastly - all well formulated products containing plant oils, butters and essential oils should contain an antioxidant to protect the oils from oxidation and our creams are no different. We formulate all of our creams with a rosemary leaf extract that acts as an antioxidant.
Pheeww... hope that answers your question!Â
