If you have spent any time online lately, you have probably seen someone warning that seed oils are toxic. The fear started with food, and now it is spilling into skincare, leaving a lot of people wondering whether the plant oils in their routine are secretly bad for them. Let us clear it up honestly, because the answer is more nuanced than the headlines.
Where did the seed oil fear come from?
It started as a dietary debate. The concern is about industrial seed oils that are heavily refined and used in processed foods, and whether eating large amounts of them contributes to inflammation.
The mechanism people point to is omega-6 fatty acids, particularly linoleic acid, and the ratio of omega-6 to omega-3 in a modern diet. That is a food question, and it is genuinely still being debated among nutrition researchers rather than settled in either direction.
The problem is that a food argument got flattened into a scary slogan, seed oils are bad, and then applied to everything, including what you put on your skin.
Let us be upfront: several of ours are seed oils
We should say this before going any further, because it would be strange to defend a category without admitting we sit in it.
Rosehip is pressed from seeds. So is jojoba. Batana comes from a palm nut, argan from a kernel. By the technical definition, a good part of our range is exactly what the slogan is warning you about.
We are not going to tiptoe around that or quietly rebrand them as something else. The category is not the problem, and the rest of this piece explains why.
Is putting seed oil on your skin the same as eating it?
No, and this is the key point. Eating large quantities of refined oil over years is a completely different situation from pressing a few drops of a pure oil onto your face.
Your skin is not your digestive system. Topically applied oils largely stay in the upper layers of the skin. They are not metabolised the way dietary fat is, and the quantities involved are a rounding error by comparison.
Topically, well-made plant oils have been used for centuries to soften and protect the skin, and the evidence for that is long and reassuring. The dietary debate simply does not transfer to skincare in the way the slogans suggest.
The concern that is real, just different
There is one legitimate issue with polyunsaturated oils on skin, and it is worth knowing because almost nobody in this argument mentions it.
Oils high in polyunsaturated fatty acids oxidise. Rosehip is the clearest example in our range: it is roughly half linoleic acid, and those chains degrade on exposure to air, light and heat. An oxidised oil is genuinely not good for your skin, and it can be irritating.
So the real advice is not to avoid the category. It is to buy oil in dark glass, keep it cool and closed, and replace it when it starts to smell sharp or like crayons. That is a storage problem with a storage solution.
So what actually matters in a skin oil?
Quality and processing, far more than the word seed.
There is a real difference between a cheap, industrially refined, bleached, and deodorized oil and a pure, cold-pressed one. Cold-pressing keeps the oil intact, preserving the fatty acids and the minor compounds that make it worth using in the first place.
Even many critics of industrial oils agree that cold-pressed, minimally processed oils are a different thing entirely. The issue was never the plant. It was what industry did to it.
Watch out for the counter-marketing too
Seed-oil-free is now appearing on labels, and it deserves the same scepticism as any other unregulated claim. It has no legal definition. It tells you nothing about how the remaining ingredients were processed, how long the list is, or whether the product is any good.
A heavily refined coconut-based product can be truthfully labelled seed-oil-free. That does not make it a better choice than a cold-pressed rosehip.
Which oils should you actually trust?
Look for two things: purity and processing. A single-ingredient oil with nothing added, that has been cold-pressed rather than chemically refined, is exactly what your skin can use.
Rosehip and argan are good examples, rich in fatty acids and antioxidants when they are kept pure. If oxidation worries you specifically, squalane and jojoba are the two most stable things we sell.
The label and the processing tell you everything. A long ingredient list and heavy refining are the real red flags, not the humble seed.
Common questions
Is linoleic acid bad for skin? No. Skin prone to congestion is often lower in it, and linoleic-rich oils are commonly recommended for that reason. The dietary argument and the topical picture point in opposite directions here.
Should I avoid seed oils if I have inflammatory skin conditions? There is no good evidence that topical plant oils drive inflammatory skin disease. If you have one, the useful conversation is with a dermatologist, not with the internet.
How do I know if my oil has oxidised? Smell it. Fresh rosehip smells faintly earthy. Oxidised rosehip smells sharp and waxy. Trust your nose over the date on the bottle.
Does cold-pressed cost more? Yes, meaningfully. Lower yield from the same raw material is the whole reason.
This is why we cold-press our oils and keep them to a single ingredient. The earth already made these oils good for your skin. The trouble only ever started when they were stripped and diluted.
