Jojoba oil or sweet almond oil: which is better for skin and balms?

Both oils stayed in the top 20% of the skin's outer layer in a 2017 study. At 100 C jojoba resisted oxidation for 39.8 h, almond 17 to 23 h. Makeup compared.

Jojoba is the better oil for a balm that has to last, and sweet almond does not go any deeper into skin than jojoba does. The one in vivo study that put both oils on human skin, a 2017 confocal Raman study from the Charité in Berlin, found that "all oils remain in the upper layers" of the stratum corneum, within the top 0 to 20 percent of its thickness, almond and jojoba alike. Where the two oils really differ is chemistry. Jojoba is about 97 percent wax esters with almost no polyunsaturated chains; almond is a triglyceride oil carrying 25 to 30 percent linoleic acid. In forced oxidation at 100 C, jojoba held out for 39.8 hours and four almond oils for 17.25 to 23.49 hours. In one laboratory's tests at 120 C the gap was wider still: 24.33 hours against 3.10.

• Jojoba: 97% wax esters
• Almond linoleic: 24.6-29.8%
• Both stay in top 0-20% of stratum corneum
• Rancimat 100 C: 39.8 h against 17-23 h
• Rancimat 120 C: 24.3 h against 3.1 h
• Vitamin E: about the same

The two oils, measured side by side

No single source compares these two oils on more than one property, so the table below puts together seven: the Cosmetic Ingredient Review's 2008 jojoba assessment, which anyone can read in full; El-Mallah and El-Shami's 2009 analysis of Egyptian jojoba; Melhaoui and colleagues' 2021 analysis of four almond cultivars from eastern Morocco; Rancimat results from Fagoaga and colleagues (2026) and from Metrohm, the instrument's maker; and two in vivo skin studies from the Charité group in Berlin.

Two rows decide most choices: stability, where jojoba wins at both temperatures, and depth, where the two oils tie. The material notes for each oil on its own are on the jojoba oil and sweet almond oil ingredient pages.

Does sweet almond oil penetrate more deeply than jojoba?

No. The pages that fill the first screen of results for this comparison are mostly oil wholesalers and retailers, and several of them say almond goes deeper. One wholesaler's comparison page states that almond "penetrates deeply into the skin" and gives a reason: it "contains a higher concentration of monounsaturated fatty acids, allowing it to penetrate deeper into the skin." Neither half of that sentence survives the sources.

The depth claim. Choe, Schleusener, Lademann and Darvin, in the Journal of Dermatological Science in 2017, set out to study "mineral-derived (paraffin and petrolatum) and plant-derived (almond oil and jojoba oil) oils" on human skin in vivo, using confocal Raman microscopy to follow each oil by depth. Their result is unambiguous: "All oils remain in the upper layers of the SC (0-20% of SC thickness)". The conclusion repeats it: "Both oil types remain in the superficial layers of the SC". This is the one study we found that measured almond and jojoba side by side on living skin, and it places them in the same band. The stratum corneum is itself the dead outer layer of the skin, typically 10 to 20 micrometres thick over most of the body, as set out in moisturisers and the skin barrier, so the top fifth of it is a few micrometres.

The reason given. The reasoning runs the wrong way even on its own terms. By the manufacturer's figures reported by Fagoaga and colleagues, jojoba is 97 percent monounsaturated. Melhaoui's four almond oils were 57.3 to 64.9 percent monounsaturated. If more monounsaturates meant deeper penetration, jojoba would be the deeper oil, and the study that tested both did not find that either.

The 2017 paper does report one difference, and it is worth stating exactly because it is easy to stretch. Below the oils themselves, the authors measured how ordered the skin's own intercellular lipids were at each depth. They found that "plant-derived oils significantly changed the ICL ordering in the depths of 30% and 70-90% of the SC thickness", and wrote that this "is likely due to the penetration of free fatty acids in the deeper layers of the SC". The finding is reported for the plant oils as a group, not for almond alone; "likely" is the authors' word; and the changes at 70 to 90 percent are called "slight" at p<0.1. Nothing in it says almond oil reached deeper than jojoba, or that either reached the living cells beneath the stratum corneum.

The molecules point the same way. Almond's main species are triglycerides of oleic and linoleic acid such as triolein, which weighs about 885 daltons; the dominant jojoba esters weigh about 590 to 620, as tabulated with their sources on the lipid penetration page. Both are over the 500 dalton line that that page discusses, and the almond molecules are the larger of the two.

Why the claim persists

The claim comes in the language of feel. "Absorbs quickly", "light", "sinks in" describe what a user notices on the surface, and the competing pages use them interchangeably with "penetrates deeply". None of the depth studies measured how an oil feels, and how fast an oil seems to disappear is not evidence of where it went. If the property you want is a fast, non-greasy finish, test it directly on your own formula, as described in sensory testing.

There is one piece of evidence on the record that does describe an oil going further into skin, and it is about jojoba, not almond. The CIR assessment summarises a 1987 report in which jojoba "was reported to readily penetrate nude mouse skin", with "the main route of penetration" being the hair follicle on histological examination, and other work in which jojoba in a microemulsion raised the stratum corneum's permeability to the drug aminophylline. Hairless mouse skin and a drug microemulsion are a long way from a balm on human skin, and the same CIR panel concluded that the jojoba ingredients "are not expected to easily penetrate skin".

What jojoba actually is: the wax ester makeup

Jojoba is pressed from the seed of Simmondsia chinensis, but it is not an oil in the chemical sense. The CIR assessment, the most readable single source on its composition, describes it as "composed almost completely (97%) of wax esters of monounsaturated, straight-chain acids and alcohols with high-molecular weights (C16-C26)", and adds that "these wax esters exist principally (83%) as combinations of C20 and C22 unsaturated fatty acids and alcohols". Each molecule is one fatty acid joined to one fatty alcohol. There is no glycerol. The remainder is small: "total free acids (C16 to C24) and total alcohols (C16 to C26) each account for 1%", and sterols are under 0.5 percent.

The CIR names the chains. The acids are "mixtures of cis-11-eicosenoic acid (C20) and cis-13-docosenoic acid (C22)", with "small quantities of oleic acid (C18) and cis-15-tetracosenoic acid (C24)". The alcohols are eicosenol, docosenol and tetracosenol. El-Mallah and El-Shami's gas chromatography gives the proportions for one Egyptian crop, and the size distribution of the whole ester molecules:

Read the two halves together and the C42 peak explains itself: a C20 acid on a C22 alcohol, or a C22 acid on a C20 alcohol, makes a 42 carbon ester, and those are the two most common chains on each side. The CIR quotes another analysis in which the single largest ester, docosenyl eicosenoate, a C22:1 alcohol on a C20:1 acid, made up 37.8 percent of the wax.

One figure in the Egyptian analysis needs a flag. It found 8.7 percent linoleic acid, a polyunsaturated acid, among the fatty acids. The CIR's description lists no polyunsaturated acid at all, and the manufacturer figures in the Fagoaga study give 1 percent polyunsaturates. Composition "varies with maturity of the seeds and somewhat with plant location and climate", in the CIR's words, and the Egyptian crop came from newly cultivated desert land. The safe reading is that jojoba is overwhelmingly monounsaturated, and that a specific lot's polyunsaturate content is a number to ask your supplier for, not one to assume is zero.

The sebum comparison that every jojoba page makes has a real basis. Human sebum is about a quarter wax esters, a figure set out with its source on the tallow against shea butter page, and jojoba is nearly all wax esters. Almond, like most plant oils, has none. What the overlap does not support is the claim, also on the competing pages, that jojoba "helps regulate sebum production". None of the sources here tested that.

What sweet almond oil is

Sweet almond oil is a conventional triglyceride oil: three fatty acids on a glycerol backbone. Melhaoui and colleagues pressed four European cultivars grown in eastern Morocco, Marcona, Fournat, Ferragnes and Ferraduel, in a screw press, and analysed each.

The Moroccan oils carried more linoleic acid than the same cultivars grown in Spain, Turkey, Argentina and Tunisia, which the paper lists at 16.4 to 21.47 percent. So almond's polyunsaturate content is not a fixed property of the species; it moves by several points with cultivar and growing region. The same paper ran the statistics on what drove stability across its four oils, and the answer was linoleic acid. The induction time correlated negatively with linoleic content (r = -0.94) and positively with the oleic to linoleic ratio (r = 0.95), and "no correlation was obtained with tocopherol content". The Fournat oil, with the most linoleic acid, had the shortest induction time.

The same oils are set against the rest of the cupboard in the oil comparison table.

Shelf life: what the oxidation tests show

Rancimat testing heats an oil under a stream of air and records when its volatile breakdown products start to accumulate. The time to that point is the induction period, the closest thing to a measured stability figure that exists for cosmetic oils.

At 100 C the gap is about two to one. Jojoba's 39.8 hours is 1.7 times the best almond (23.49) and 2.3 times the worst (17.25). These two figures come from different laboratories, so read the ratio as approximate. In the Fagoaga run jojoba also outlasted olive, sunflower and rosehip, results the authors say "correlated with PUFA levels".

At 120 C, in one laboratory, the gap is roughly 8 to 17 times. The Metrohm table is the only source here that tested both oils under the same conditions. Its three cold-pressed and organic jojobas ran 23.73 to 25.01 hours and its three almonds 1.47 to 3.10. The gap widening with temperature is what you would expect if jojoba's resistance comes from its chain structure and almond's from a stock of antioxidant that heat uses up faster, but none of the sources tested that explanation, so take it as a reading, not a finding.

Refining cost jojoba a third of its stability in that table. Refined organic jojoba ran 16.26 hours against 23.73 to 25.01 for the unrefined ones. It still outlasted every almond oil by more than five times.

The vitamin E row: why it does not explain the gap

The obvious explanation for jojoba's stability would be more antioxidant. The sources rule it out. The CIR gives jojoba "~0.05% tocopherols", about 500 mg per kg. Melhaoui's almond oils carried 409 to 492 mg per kg. On total vitamin E the two oils are in the same range.

Two further findings point the same way. Fagoaga and colleagues measured total antioxidant capacity and found "jojoba the lowest at 298 K", that is, at 25 C, among the four oils they tested, yet jojoba had the longest induction period. And within the almond set, Melhaoui found no correlation between tocopherol content and stability, while linoleic acid predicted it closely. The tocopherols also differ in kind: almond's are almost all alpha-tocopherol (401 to 474 mg per kg of the totals above), while the Egyptian jojoba was 79.2 percent gamma-tocopherol and 20.3 percent alpha.

So jojoba's stability comes from the molecule, not its vitamin E, and almond's limit is its 25 to 30 percent linoleic acid. Adding more alpha-tocopherol to an oil that already carries 400 to 500 mg per kg of it is not the fix. Mixed tocopherols and rosemary extract, and the levels at which they help, are covered in vitamin E and antioxidants. Once the oil already smells of crayons, nothing reverses it; the signs are in rancid balm.

Occlusion, irritation and allergy

Occlusion. Patzelt and colleagues, in Skin Research and Technology in 2012, measured transepidermal water loss after applying four vegetable oils, among them jojoba, plus paraffin oil, with petrolatum as the positive control, on six healthy volunteers. Their result: "the application of the vegetable oils (except jojoba oil) as well as paraffin oil, led to a similar occlusion of the skin surface", and "the most effective occlusion was found for petrolatum". Jojoba was the exception. The abstract does not say in which direction, and it does not name the other three vegetable oils, so it cannot tell you whether almond was one of them. The authors call the oils' effect "a semi-occlusion". If reducing water loss is the job, the oil is not the ingredient doing it; see occlusive, emollient and humectant.

Irritation. The CIR assessment reports that "in clinical tests, Simmondsia Chinensis (Jojoba) Seed Oil was neither a significant dermal irritant, nor a sensitizer", and the panel judged it safe "at concentrations up to 100% in body and hand creams". None of the sources on this page reports a comparable clinical test for sweet almond oil, so this page does not rank the two on irritation.

Allergy. Almond is a tree nut, and jojoba is not. That does not mean an almond balm needs an allergy warning: cosmetic labels have no declarable nut allergen class, and almond appears in the ingredient list under its INCI name. What the protein residues in refined and cold-pressed almond oil amount to, and how the UK, EU and US treat them, is worked through in nut oil allergy. For a product meant for children, or sold where you cannot talk to the buyer, jojoba removes the question entirely, and a worked formula is in nut free balm.

Which to choose for which product

In a blend the least stable oil sets the pace, so a balm that is half almond has a shelf life closer to almond's than to jojoba's. The oil blend calculator gives the weighted index for any blend. A worked lip formula using either oil is in how to make lip balm, and a body product built for the almond end of the table is in massage balm. For the cleansing case, where jojoba's wax esters do a job of their own, see cleansing balm.

What these numbers do not settle

Depth. The depth comparison rests on one study, Choe 2017, whose abstract does not give subject numbers, dose or timing, and which tested neat oils, not balms. The Patzelt study found the vegetable oils it tested "only into the first upper layers of the stratum corneum", but its abstract does not name almond. The case against "almond penetrates more deeply" is that the only direct comparison found no such difference and that the stated reason contradicts the oils' own composition. It is not a measurement of every almond oil on every skin.

Stability. The 100 C comparison joins two laboratories. The 120 C comparison is one manufacturer's table that does not state air flow, sample mass or number of runs. Both point the same way; neither predicts a shelf life in months.

Composition. Jojoba's ester distribution comes from one Egyptian crop and almond's from four cultivars in one region. The certificate of analysis for the lot you buy outranks every figure on this page.
