Jojoba oil shows genuine promise for psoriasis, though the evidence is stronger for some uses than others. Its unusual chemical makeup closely resembles the waxy esters your skin produces naturally, which gives it an edge over many plant oils when it comes to moisturizing and softening psoriatic plaques. Laboratory studies confirm anti-inflammatory and wound-healing properties, and one clinical trial found it dramatically improved the delivery of a prescription psoriasis drug through the skin. What jojoba oil lacks, so far, is a large clinical trial testing it as a standalone psoriasis treatment.
Why Psoriatic Skin Desperately Needs Moisture
Psoriasis is fundamentally a disease of barrier breakdown. The rapid turnover of skin cells in a psoriatic plaque means the outermost layer never fully matures, leaving gaps that let water escape far faster than normal. Researchers measure this escape rate as transepidermal water loss, and in people with psoriasis it is significantly elevated across both affected and unaffected skin compared to people without the condition.1PubMed Central. Transepidermal Water Loss in Psoriasis: A Case-control Study Plaques themselves lose water the fastest, but even nearby skin that looks normal has a measurably weaker barrier. A separate study confirmed that psoriatic plaques also have lower hydration, reduced elasticity, and more redness compared to uninvolved skin.2PubMed Central. Epidermal Barrier Parameters in Psoriasis: Implications in Assessing Disease Severity
This is why emollients are considered a baseline part of psoriasis management regardless of what other treatments you use. Anything that slows water loss and keeps the outer skin layer flexible can reduce scaling, cracking, and itch. The question with any specific oil is whether it does something beyond generic moisturizing.
What Makes Jojoba Oil Chemically Unusual
Most plant oils are triglycerides, meaning three fatty acid chains attached to a glycerol backbone. Jojoba is not actually an oil in that sense. About 98% of it is composed of long-chain wax esters, with only trace amounts of free fatty acids and alcohols.3PubMed Central. Jojoba Oil: An Updated Comprehensive Review on Chemistry, Pharmaceutical Uses, and Toxicity The dominant wax esters are built from chains of 40 to 44 carbon atoms, with the 42-carbon ester making up roughly half the total.4Journal of the American Oil Chemists’ Society. Jojoba oil wax esters and derived fatty acids and alcohols: Gas chromatographic analyses
This matters for psoriasis because human sebum also contains wax esters. The similarity means jojoba integrates well with the skin’s own lipid film rather than sitting on top of it the way many heavier oils do. For people with psoriasis, whose barrier is already compromised, a product that blends into the remaining lipid structure rather than forming a separate greasy layer tends to feel more comfortable and may support the barrier more effectively.
Anti-Inflammatory and Wound-Healing Properties
Psoriasis is driven by chronic inflammation, so any topical product worth considering should ideally do more than just seal in moisture. A comprehensive review of jojoba oil’s pharmacological profile lists anti-inflammatory activity among its documented properties, alongside antioxidant, antibacterial, and specific antipsoriasis effects.3PubMed Central. Jojoba Oil: An Updated Comprehensive Review on Chemistry, Pharmaceutical Uses, and Toxicity Much of this evidence comes from laboratory and animal models rather than human psoriasis trials, which is an important caveat. But the anti-inflammatory signal is consistent across multiple types of experiments.
One property that is particularly relevant to psoriasis is jojoba oil’s effect on skin cell repair. In laboratory scratch-wound experiments, jojoba liquid wax accelerated the closure of wounds in both keratinocytes (the main cells of the outer skin layer) and fibroblasts (the cells that produce structural support beneath them).5PubMed. Wound healing properties of jojoba liquid wax: an in vitro study Psoriatic skin is in a constant state of micro-damage from rapid cell turnover, cracking, and scratching. Anything that supports the repair process in those cell types is at least theoretically useful, even if in-vitro results do not always translate directly to what happens on living skin.
The Strongest Evidence Is for Jojoba as a Drug Carrier
Where jojoba oil has the most impressive clinical data in psoriasis is not as a standalone treatment but as a vehicle for delivering prescription drugs more effectively through the skin. Researchers formulated a jojoba oil-based microemulsion containing tazarotene, a synthetic retinoid used for psoriasis, and tested it against the standard marketed gel in actual psoriasis patients. The jojoba formulation doubled the amount of drug deposited in the skin and produced a 68% reduction in disease severity scores, compared to just under 9% with the conventional gel.6PubMed.

That is a striking difference. The jojoba microemulsion did not just marginally improve delivery; it transformed a modestly performing treatment into a highly effective one. Separate research has confirmed jojoba oil’s ability to enhance transdermal permeation of other drugs as well, including pain relievers and local anesthetics.7PubMed Central. Jojoba oil-based microemulsion for transdermal drug delivery The wax ester structure seems to interact with the skin’s lipid layers in a way that opens pathways for active ingredients to penetrate more deeply.
For someone with psoriasis, this finding has a practical takeaway even without access to a specialized compounding pharmacy. Applying jojoba oil before or alongside certain topical medications could theoretically improve their absorption. That said, you should check with your dermatologist before layering oils with prescription treatments, because enhanced absorption can also mean enhanced side effects.
How Jojoba Oil Interacts with Phototherapy
Phototherapy, particularly narrowband UVB, is one of the most effective treatments for moderate to severe psoriasis. If you use light therapy, what you put on your skin beforehand matters more than most people realize. A review in the dermatology literature found that thin, liquid-type emollients like mineral oil and glycerol actually improved psoriatic plaque clearance during phototherapy, while thicker products like petrolatum and salicylic acid ointments reduced it by physically blocking UV penetration.8PubMed. The impact of emollients on phototherapy: a review
An earlier study specifically tested whether common topical preparations interfered with the skin’s UV response. Clear liquid emollients and mineral oil did not significantly affect UVB transmission or the skin’s erythema reaction. Tar-containing products and salicylic acid, on the other hand, actively blocked UVB. Thick applications of petrolatum and emollient creams also reduced UV transmission to a meaningful degree.9Journal of the American Academy of Dermatology. Effects of topical preparations on the erythemogenicity of UVB: Implications for psoriasis phototherapy
Jojoba oil was not directly tested in these studies, but it is a clear, thin liquid at room temperature with properties similar to the serous-type emollients that performed well. It does not contain tar or salicylic acid, and its consistency is far thinner than petrolatum. Based on what we know about UV transmission and emollient thickness, jojoba is unlikely to interfere with phototherapy the way heavier ointments can, and it may even help by hydrating plaques enough that UV penetrates the scale more evenly. Still, if phototherapy is a regular part of your regimen, it is worth mentioning your oil use to the technician or dermatologist supervising your sessions.
What Jojoba Oil Cannot Do
It would be misleading to suggest that jojoba oil can replace medical treatment for psoriasis. The condition involves deep immune system dysregulation, with overactive T cells driving the rapid skin turnover that produces plaques. No topical oil addresses that underlying immune dysfunction. Biologics, systemic medications, and even targeted topical steroids work on pathways that jojoba oil simply does not reach.
The evidence for jojoba’s antipsoriasis activity, while real, comes largely from laboratory studies and from its role as a drug delivery vehicle rather than from trials testing it on its own in patients with psoriasis.10PubMed. Bioactivities of Jojoba Oil Beyond Skincare The review literature acknowledges antipsoriasis properties as part of jojoba’s broad pharmacological profile, but large-scale human trials with jojoba oil alone have not been published. For mild psoriasis or for someone who wants to reduce reliance on medicated products during quieter periods, jojoba might be a reasonable supportive therapy. For active, spreading, or moderate-to-severe disease, it should be part of a broader treatment plan, not a substitute for one.
Safety and Potential Risks
Jojoba oil has a good safety profile for topical use. It is widely used in cosmetics and personal care products, and allergic contact dermatitis from pure jojoba oil is rare. A comprehensive review covering the oil’s chemistry, uses, and toxicity addresses safety but does not report significant adverse-event data or high rates of skin irritation.3PubMed Central. Jojoba Oil: An Updated Comprehensive Review on Chemistry, Pharmaceutical Uses, and Toxicity That said, psoriatic skin is more reactive than healthy skin, and the impaired barrier means substances penetrate more readily. If you have never used jojoba oil before, testing it on a small area of uninvolved skin for a day or two before applying it to a plaque is a sensible precaution.
A few practical risks are worth noting:
- Adulteration: Cheap jojoba products are sometimes diluted with other oils or contain added fragrances that can irritate psoriatic skin. Look for products labeled as 100% pure, cold-pressed jojoba oil with no added ingredients.
- Oral ingestion: Jojoba oil is not meant to be eaten. The wax esters are not digestible by humans, and ingesting jojoba oil can cause gastrointestinal distress. This is only relevant because some natural-health sources recommend oral supplementation with various oils.
- Over-application before phototherapy: While jojoba is thin enough to be unlikely to block UV, applying a very heavy layer of any oil could theoretically interfere with light transmission. A thin coat is sufficient.
- Delayed treatment: The biggest risk with any complementary approach is that it delays someone from starting or continuing effective medical therapy. If your psoriasis is getting worse, jojoba oil is not the answer on its own.
How to Use Jojoba Oil for Psoriasis Practically
If you want to incorporate jojoba oil into your psoriasis management, the most effective approach is to apply it to damp skin right after bathing. This traps moisture beneath the oil layer and maximizes the barrier-repair benefit. You only need a thin layer, roughly a few drops spread across each affected area. Jojoba absorbs relatively quickly compared to thicker emollients, so it works well under clothing without leaving heavy residue.
For scalp psoriasis, jojoba oil can be particularly useful because its liquid consistency allows it to spread through hair without the clumpy, waxy buildup that thicker products leave behind. Massaging a small amount into the scalp before bed, then washing it out in the morning, can help soften and loosen scale. Some people find that this makes subsequent medicated shampoos more effective because the scale is already partially lifted.
Jojoba can also be mixed with a drop or two of certain essential oils that have independent anti-inflammatory evidence, though you should be cautious about this with psoriasis. Essential oils are concentrated plant extracts and many are irritating to compromised skin. Tea tree oil and lavender oil are sometimes recommended, but both can cause contact sensitization, especially on broken or inflamed skin. If you want to add anything to your jojoba oil, start with very low concentrations and watch for increased redness or stinging.
How Jojoba Compares to Other Common Oils
A review of natural oils for skin-barrier repair examined several plant-based oils used in dermatology, including jojoba, coconut, sunflower seed, olive, oat, and argan oils.11Journal of the American Academy of Dermatology. Natural Oils for Skin-Barrier Repair: Ancient Compounds Now Backed by Modern Science The review did not produce head-to-head comparative data ranking these oils for psoriasis specifically, but the differences in their composition suggest they serve somewhat different roles.
Coconut oil has well-documented antimicrobial properties and contains lauric acid, which can fight certain bacteria. However, some people with psoriasis find it mildly irritating, and it is a solid at room temperature, which means it behaves more like a thick emollient. Olive oil, despite its reputation, has been shown in some research to actually disrupt the skin barrier when used topically over time. Sunflower seed oil, rich in linoleic acid, has better evidence for barrier repair in conditions like eczema. Jojoba’s advantage over all of these is its wax ester composition, which no other commercially available plant oil shares. That unique chemistry means it does not go rancid as quickly as triglyceride-based oils, and it integrates with the skin’s own lipid layer rather than just coating the surface.
For people who have tried multiple oils and found them too heavy, too greasy, or irritating, jojoba is often the best tolerated option. Its texture is closer to a serum than a traditional oil, and it does not leave the shiny, occlusive film that many people dislike about petroleum-based emollients.
The Accessibility Factor
Part of jojoba oil’s appeal for psoriasis is practical rather than pharmacological. Psoriasis is a lifelong condition, and the costs of prescription treatments, dermatologist visits, and phototherapy sessions add up. Plant-based remedies have historically attracted interest in part because of their relatively low cost and wide availability.12PubMed Central. Progress and prospects in the management of psoriasis and developments in phyto-therapeutic modalities A bottle of pure jojoba oil costs a fraction of most prescription emollients and lasts for weeks of daily use.
That economic reality matters when you consider adherence. Dermatologists frequently emphasize that the best moisturizer for psoriasis is the one you actually use consistently. A product that feels pleasant on the skin, does not stain clothing, absorbs quickly, and does not require a prescription has a practical advantage over one that may be technically superior but sits unused in a medicine cabinet. Jojoba checks many of those boxes, which may explain why it keeps showing up in patient forums and complementary medicine discussions about psoriasis even without a large randomized trial to back it up.
None of this changes the fundamental picture: jojoba oil is a supportive therapy with genuine but limited evidence for psoriasis, not a proven standalone treatment. Its best-supported role is as a well-tolerated emollient that may offer mild anti-inflammatory benefits and can dramatically improve the delivery of medicated topicals through the skin. For many people with psoriasis, that combination of comfort, safety, and synergy with other treatments is enough to make it worth trying.
