Plant Oils vs Mineral Oils: What Dermatologists Recommend
The Great Oil Debate That Started at My Kitchen Table
My grandmother swore by olive oil for everything. Cooking, sure, but also her face, her hands, even her elbows when winter got harsh. “Why would I buy fancy creams when the earth gives us this? " she’d say, pouring golden liquid into her palm.
Meanwhile, my mom’s medicine cabinet looked different. Rows of products with mineral oil listed somewhere in the ingredients. Baby oil - cold cream. That thick moisturizer she’d been using since the 80s.
So when I started actually caring about what I put on my skin-somewhere around my late twenties when fine lines appeared like uninvited guests-I found myself caught between two worlds. Plant oils felt virtuous, natural, connected to something ancestral. Mineral oils felt - suspicious? Industrial? But also familiar and trusted by generations.
I needed answers - real ones. Not from influencers selling me $80 serums.
What Dermatologists Actually Say (Not What You’d Expect)
Here’s where things got interesting. I started asking dermatologists-not the ones on TikTok, but actual board-certified doctors I tracked down through medical journals and professional interviews. Their answers surprised me.
Dr. Rachel Nazarian, a dermatologist at Schweiger Dermatology Group in New York, put it bluntly in an interview I found: “Mineral oil has been unfairly demonized. " She explained that pharmaceutical-grade mineral oil is highly purified, non-comedogenic for most people, and creates an excellent barrier to prevent moisture loss.
Wait, what?
I’d spent years avoiding mineral oil because internet wellness culture told me it was basically coating my face in motor oil. But dermatologists kept saying the same thing: the mineral oil in cosmetics isn’t the same as industrial petroleum. It’s refined - purified. Safe.
Dr. Hadley King, another NYC-based dermatologist, explained something that clicked for me: “Plant oils can be wonderful, but they’re not universally better. Some people react badly to plant oils because they contain proteins and compounds that can trigger sensitivities.
Thing is, “natural” doesn’t automatically mean gentler. Poison ivy is natural - so is arsenic.
My Personal Experiment (Results Were Humbling)
I decided to test this myself. Three months - two oils. One face.
First month: rosehip seed oil, a darling of the clean beauty world. Cold-pressed, organic, the whole deal - my skin… hated it. Within two weeks, tiny bumps appeared along my jawline. Nothing dramatic, but persistent. I kept going because surely my skin just needed to “adjust. " (Spoiler: it didn’t.
Second month: I switched to a simple mineral oil-based product. Plain, unsexy, cheap. The bumps disappeared within a week. My skin felt soft - not magical or transformed, just… good - normal. Hydrated.
Third month: I tried jojoba oil, which technically isn’t an oil but a wax ester. This one worked beautifully for me. No breakouts, nice absorption, slight glow.
My takeaway? My grandmother’s advice worked for her skin. Not necessarily mine - skin is personal. Frustratingly, individually personal.
The Science Behind Plant Oils (It’s Complicated)
Plant oils contain fatty acids, antioxidants, vitamins, and other bioactive compounds. That sounds impressive-and it is. These components can genuinely benefit skin.
Argan oil contains vitamin E and ferulic acid. Marula oil has oleic acid and antioxidants. Sea buckthorn oil packs omega-7 fatty acids that support skin healing.
But here’s what the clean beauty marketing doesn’t emphasize: these same bioactive compounds can cause reactions. Oleic acid, abundant in olive oil and argan oil, can actually disrupt the skin barrier in some people. A 2018 study in the International Journal of Molecular Sciences found that oils high in oleic acid might increase transepidermal water loss in certain skin types.
Meanwhile, oils high in linoleic acid-like sunflower seed oil or safflower oil-tend to be better tolerated by acne-prone skin. The ratio matters - the specific plant matters. Your individual skin chemistry matters.
Mineral oil, by contrast, is inert. It doesn’t penetrate deeply. It just sits on top, forming a protective layer. Boring - maybe. But predictable. Safe for most people, including those with sensitive or reactive skin.
When Plant Oils Win
I’m not here to tell you plant oils are bad. They’re not - for many people, they’re fantastic.
If you have dry, mature skin without sensitivity issues, plant oils rich in antioxidants might offer benefits mineral oil can’t-actual nourishment versus just protection.
Squalane (derived from olives) is lightweight, non-comedogenic, and mimics compounds our skin produces naturally. It’s become a favorite among dermatologists for good reason.
Hemp seed oil has a fatty acid profile that closely matches human skin. Tamanu oil has research supporting its wound-healing properties.
The key is matching the right oil to your specific skin. And that takes experimentation - patch testing. Patience.
When Mineral Oil Makes More Sense
Dermatologists frequently recommend mineral oil-based products for:
Eczema sufferers - the occlusive barrier helps prevent flare-ups
Post-procedure skin - after chemical peels or laser treatments, you want inert, non-irritating hydration
Babies and children - baby oil exists for a reason; it’s gentle and unlikely to cause reactions
Extremely sensitive skin - when everything else causes problems, mineral oil often doesn’t
Removing makeup - it dissolves products effectively without harsh surfactants
Dr. Shereene Idriss has noted that mineral oil’s occlusive properties make it excellent for preventing moisture loss overnight. It’s not about absorption or penetration-it’s about protection.
The Truth About “Clogged Pores”
This myth persists: mineral oil clogs pores. The evidence doesn’t support this for most people.
Comedogenicity studies from the 1970s and 80s gave mineral oil bad marks, but those studies used crude, industrial-grade oil on rabbit ears. Modern cosmetic-grade mineral oil performs differently. A 2005 study in the Journal of Cosmetic Dermatology found highly refined mineral oil to be non-comedogenic.
That said, everyone’s skin responds differently. Some people do break out from mineral oil. Some people break out from coconut oil, which scores high on the comedogenic scale despite being “natural.
The only way to know is to try. Carefully.
What I Use Now
After all my research and experimentation, my routine looks like this:
Morning: Squalane. Lightweight, absorbs quickly under sunscreen, doesn’t cause breakouts for me.
Evening: A mineral oil-based cleansing oil to remove makeup, followed by whatever moisturizer my skin feels like it needs.
Occasional treatment: Rosehip oil on my body (where it doesn’t break me out), especially on dry patches during winter.
I stopped being dogmatic. I stopped believing one type of oil was morally superior to another. I started listening to dermatologists and my own skin.
The Real Recommendation
Most dermatologists I’ve researched say the same thing: there’s no universal winner in plant oils versus mineral oils. Both have legitimate places in skincare.
What matters is:
- Understanding your skin type and concerns
- Patch testing new products
- Paying attention to how your skin actually responds
- Ignoring fear-mongering about ingredients that have decades of safety data
My grandmother was right-for her. The earth did give us wonderful oils. But it also gave us the knowledge to refine and purify substances that work beautifully for different skin needs.
I think she’d appreciate that nuance. She was practical above everything else.
And practical means using what works. Not what sounds best in an Instagram caption.
