Ingredients Explained
Helianthus Annuus Seed Oil is a plant oil derived from the seeds of a sunflower.
It is rich in fatty acids, primarily linoleic acid and oleic acid. This gives it emollient and skin conditioning properties.
The reason this ingredient is so effective is because it forms a thin film on the skin that reduces transepidermal water loss (TEWL) while supplying linoleic acid to the stratum corneum to improve barrier strength.
The high linoleic acid content is particularly noteworthy for acne-prone skin.
Research suggests that acne-prone skin tends to be deficient in linoleic acid in sebum. Topical application may help replenish this to support a healthier follicular environment and less comedone-promoting sebum.
One randomized study found sunflower seed oil preserved skin barrier integrity in adult volunteers with and without atopic dermatitis (outperforming olive oil).
This ingredient is well-studied, gentle, and an effective emollient suitable for most skin types.
On fungal acne: This ingredient may not be Fungal acne (Malassezia folliculitis) safe. This is because it contains fatty acids with carbon chain lengths in the C11-C24 range.
Learn more about Helianthus Annuus Seed OilEthylhexyl Palmitate, also known as octyl palmitate, is created from 2-ethylhexyl alcohol and palmitic acid.
In cosmetics, it plays many roles:
One thing worth noting: a controlled study found this ingredient applied under occlusion to acne-prone subjects increased microcomedones. Just keep in mind this was under occlusive conditions and don't reflect how most products are used day-to-day.
For most people, this is a well-tolerated and lightweight ingredient.
This ingredient may not be fungal acne safe because it is an ester of palmitic acid, a C16 fatty acid that falls within the C11-24 range that Malassezia can metabolize.
You'll see this one rated 4 comedogenic all over the internet. That number isn't from a single study, and the actual research is more interesting.
The original rating comes from 1980s rabbit ear tests (which are a shaky basis for anything). But Ethylhexyl Palmitate is one of the few ingredients with real human data behind it. A 2021 controlled trial found this ingredient increased microcomedones by an average of 365% over four weeks.
Just know that test used the pure ingredient under an occlusive pad on back skin; most products use it at much lower levels alongside other ingredients and plenty of people use those with no issue.
Learn more about Ethylhexyl PalmitateCaprylic/Capric Triglyceride (aka MCT Oil) is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping to prevent moisture loss.
Though it behaves like an oil, it is not technically one due to its chemical composition. One perk of this ingredient is that it is very stable, resistant to oxidation, and unlikely to go rancid.
In practice, that translates to a long shelf life and a consistently elegant skin feel.
While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Just patch test if you have concerns.
Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source.
This ingredient is treated as the gold standard fungal acne safe oil. Even though it is coconut derived, the problematic lauric acid is stripped out.
This leaves just caprylic (C8) and capric (C10) acid. These chain lengths actually trend antifungal; a 2020 study found caprylic acid was enough to disrupt Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%.
Learn more about Caprylic/Capric TriglycerideThis ingredient is also known as castor oil. It is a skin conditioning ingredient.
The star component of castor oil is ricinoleic acid, an unusual fatty acid that makes up ~80-92% of its composition.
In skincare, it is an emollient that dries down to a solid film with water-binding properties. This helps keep skin hydrated and helps reduce transepidermal water loss (TEWL).
A 2026 dermatology review pulls together its broader uses:
Human clinical testing found this ingredient to be non-irritating and non-sensitizing.
Because castor oil contains fatty acids in the C11-24 range, this ingredient may not be fungal acne safe.
At this time, the literature does not support castor oil in regrowing hair. A 2022 systematic review found no strong evidence that it supports hair growth and only weak evidence that it improves hair shine.
Castor oil itself carries "perfuming" and "masking" function tags according to the official CosIng database. This is because of its mild odor and odor-dampening properties.
Learn more about Ricinus Communis Seed OilThis ingredient is also known as coconut oil. It is a plant-derived ingredient with skin conditioning properties.
The fatty acid profile of coconut oil is mostly lauric acid (~54%), followed by capric, caprylic, palmitic, and myristic acids. This profile allows it to penetrate easily into skin, moisturize, and improve dry skin.
A double-blind study confirmed that extra virgin coconut oil is as effective as mineral oil for treating very dry skin. Another study found it outperformed mineral oil for mild to moderate atopic dermatitis in children.
Another study from 2018 found that virgin coconut oil can soothe inflammation and boost key skin barrier proteins. Just know this evidence is still only from lab settings and not human trials.
It has also been shown to reduce Staphylococcus aureus, a bacteria that commonly overgrows in people with eczema.
Clinical testing shows very minimal skin irritation and no evidence of sensitization or phototoxicity.
Coconut oil gets flagged as a "fragrance" because it has a natural mild scent (not because it's a synthetic perfume). The European Cosmetic ingredient database also lists "perfuming" as a function of this ingredient.
Just so you know, the term "fragrance" is completely unregulated. Some brands still use botanical extracts or essential oils in their "fragrance-free" formulas, but regulatory databases technically classify these under "fragrance".
Coconut oil has a tiny and useless bit of natural SPF. Early lab studies clocked it around SPF 7-8 but a more recent study found the real number closer to SPF 1.2. It also offers no meaningful UVA protection (SPF only overs UVB rays).
The comedogenic rating of 4/5 means it has a high potential to clog pores; but it's worth noting that comedogenicity is highly individual and ratings cannot predict how an overall formula will behave on skin.
Since lauric acid is the dominant fatty acid, this ingredient may not be fungal acne safe. The Malassezia yeast feeds on fatty acids with carbon chain lengths between 11-24, and lauric acid falls within these lengths (C12).
Learn more about Cocos Nucifera OilCaprylyl Caprylate/Caprate is a synthetic blend of caprylic acid and capric acid.
As an emollient, this ingredient helps moisturize the skin. Emollients create a barrier on the skin that prevents water from escaping.
Sesamum Indicum Seed Oil is the cold-pressed oil from sesame seeds.
It is an emollient and skin conditioning agent made up of roughly 82-85% unsaturated fatty acids, mostly linoleic (~41%) and oleic acid (~39%).
This pairing gives it barrier-supporting and moisturizing properties. Linoleic acid, an essential omega-6 fatty acid, can be incorporated into complex skin lipids. Topical application has shown barrier repair, anti-inflammatory, and wound-healing effects in cell and animal studies.
Beyond fatty acids, sesame oil brings something more distinctive to the table:
It contains natural antioxidants sesamol, sesamolin, and gamma-tocopherol. These also give the oil notably high oxidative stability.
One of the oil's key lignans, sesamin, has also demonstrated anti-inflammatory activity in preclinical models.
A 2023 clinical study found that a single application of sesame seed oil to the forearms of 35 healthy women improved stratum corneum hydration (though it didn't outperform raspberry seed oil).
The comedogenic rating of 1-3 depends on the type of sesame oil; unrefined carries a rating of 3 while refined sesame oil drops to a 1.
Human testing has proved that any finished product with a comedogenic ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin.
This ingredient may not be safe for fungal acne as it contains fatty acids that can feed Malassezia.
Learn more about Sesamum Indicum Seed OilSqualane is the hydrogenated and shelf-stable form of squalene (a lipid that naturally occurs in human sebum).
It is an emollient and skin conditioning agent that is able to integrate seamlessly into the skin's lipid barrier without clogging pores.
This is due to how structurally similar it is to what your skin already produces.
Though it is mostly an emollient that helps soften and hydrate skin, it also has some humectant and occlusive action. Humectants help the skin retain moisture while occlusives seal it in, making squalane a triple-threat moisturizer.
Research shows it has antioxidant capabilities that help protect against stressors like UV exposure, specifically UVA induced oxidative stress. This study also found that it supports collagen biosynthesis in human dermal fibroblasts.
No clinical study has reported significant adverse effects and irritation reactions are very rare from this ingredient (even at 100% concentration).
Overall, it's a fantastic ingredient for hydration and is suitable for all skin types.
This depends on the source. Squalane can be derived from both plants and animals. Most squalane used in skincare comes from plants.
Please note: the source of squalane is only known if disclosed by the brand. We recommend reaching out to the brand if you have any questions about their squalane.
Read more about squalene with an "e".
Though squalane is often called an oil, it’s technically not one. It is a hydrocarbon, meaning it is only made of carbon and hydrogen. True oils are triglycerides and made of fatty acids and glycerol.
The term “oil-free” isn’t regulated so companies can define it however they want. Some exclude all oils, while others just avoid mineral oil or comedogenic oils.
Squalane has a comedogenic rating of 1 from the original 1972 study that tested raw ingredients under occlusion on rabbit ears. This system is not standardized or peer-reviewed, and using the raw ingredients is very different from how diluted cosmetic formulations are used on human skin.
A comedogenic rating of 1 means it is "unlikely to clog pores" according to the original rating system.
The overall formula of a product matters more than the individual ingredients on whether or not it will cause clogged pores.
Learn more about SqualaneBisabolol is a gentle skin conditioner, antioxidant, and soothing ingredient.
It's primary claim to fame is soothing and research shows topically applied bisabolol can quiet the chemical messengers that cause your skin to become inflamed, helping to sooth any irritation.
A clinical study found that applying 0.5% bisabolol daily for 8 weeks produced an average 9% decrease in skin pigmentation. Researchers found it can also suppress the process that leads to excess melanin production in skin.
In vitro studies found that bisabolol combined with propylene glycol significantly increased skin permeability by increasing lipid fluidity in the stratum corneum.
You'll likely see use concentrations quite low, usually 0.1-0.2%.
Overall, this is a well-tolerated ingredient that works well in formulas designed for sensitive, reactive, or post-procedure skin.
Learn more about BisabololTocopheryl Acetate is a stable, shelf-friendly form of vitamin E.
Formulators love it because plain vitamin E oxidizes quickly once it hits air. This acetate version stays stable and resists going off, helping to extend a product's shelf life.
It's actually inactive on its own and works like a slow-release "storage" form; the enzymes in your skin called esterases gradually convert it into active vitamin E over time.
One in vivo study showed 5% of the acetate in the living layer of the epidermis converted to vitamin E after 5 days of application. This study also found the skin gained protection against UV damage even though the conversion was slow and small.
Once converted, vitamin E acts as a skin's main fat-soluble antioxidant that fights free radicals to protect skin from damage.
Topical vitamin E generally boosts the skin's photoprotection, and it reduced UV-damage in animal models.
This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.
Overall, it has a pretty solid safety profile and has been found to be non-irritating and non-comedogenic. Allergic reactions may happen but stay rare due to how widely the ingredient gets used.
The concentration will vary depending on the formula; industry data shows 0.1% in baby lotions, 3% in lipsticks, and 5% in foot powders. You can also find this ingredient at 100% in a pure vitamin E oil.
Most leave-on skincare keeps it at the lower end, often between 0.5-1%.
Learn more about Tocopheryl AcetateBis-PEG/PPG-14/14 Dimethicone is a silicone + PEG/PPG hybrid that mainly works as an emulsifier.
It helps water and silicone oils play nicely together in water-in-silicone formulas (think primers, silky sunscreens, long-wear makeup).
Chemically, it's basically a dimethicone that's been made more water-friendly by attaching ethylene oxide (PEG) and propylene oxide (PPG) chains. That's why you'll get that classic soft feel from silicone without the formula separating.
It is able to improve stability, spreadability, and add a velvety finish in low amounts.
Learn more about Bis-PEG/PPG-14/14 DimethiconePEG-40 Hydrogenated Castor Oil is an emulsifier derived from castor oil.
As an emulsifying agent, it helps other ingredients like fragrances and fat-soluble vitamins dissolve cohesively.
Due to its large molecule size, it doesn't penetrate beyond the skin's surface.
This ingredient has a solid regulatory track record; the CIR Expert Panel first concluded it was safe for use in cosmetics at concentrations up to 100% in 1997. A 2012 reassessment reaffirmed that finding. Safety studies have also found no irritation or evidence of toxicity.
A 2019 study did find this ingredient to grow Malassezia, so this ingredient may not be fungal acne safe.
Learn more about PEG-40 Hydrogenated Castor OilVitis Vinifera Seed Oil comes from the grape vine. Grape seeds are a byproduct of creating grape juice or wine.
The components of grape seeds have many skin benefits. Research has found it to be antimicrobial and anti-inflammatory. It also contains many potent antioxidants such as Vitamin E , Vitamin C, proanthocyanidins, polyphenols, flavonoids, and anthocyanins. Proanthocyanidin has been shown to help even out skin tone.
Antioxidants help fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material. Antioxidants help stabilize free-radicals by donating extra electrons. Grape seed extract may help reduce the signs of aging.
The antimicrobial properties of grape seed may help treat acne. However, more research is needed to support this claim.
Grape seed has also been found to help absorb UV rays. Grape seed extract should not replace your sunscreen.
The fatty acids of grape seed oil give it emollient properties. Emollients help soothe and soften your skin by creating a film. This film traps moisture within, keeping your skin hydrated.
Learn more about Vitis Vinifera Seed OilThis ingredient is also known as sweet almond oil. It is a lightweight, cold-pressed oil from the ripe seeds of the sweet almond tree.
Sweet almond oil is rich in skin-nourishing fatty acids such as oleic acid (55-86%) and linolenic acid (7-35%).
As an emollient, it softens and hydrates skin by forming a thin barrier that locks in moisture.
Clinical studies have found it to be non-irritating and non-sensitizing. The CIR Expert Panel has evaluated the available safety data and concluded it is safe for topical use.
Because of the oleic acid content, this ingredient may not be fungal acne safe.
This ingredient does have a comedogenic rating of 3, but this doesn't mean a formula with this ingredient will clog pores.
Human testing has proved that any finished product with a comedogenic ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin.
Learn more about Prunus Amygdalus Dulcis OilJojoba oil is one of the most well-studied plant-derived ingredients in cosmetics. It is an emollient with a special structure.
Because it is made up of 97-98% wax esters, it closely mirrors the linear monoesters found in human sebum. This makes it skin compatible, non-greasy, and lightweight.
Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.
Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).
Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.
Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.
Fungal acne: The Malassezia yeast is known to metabolize fatty acids in the C11-24 range and jojoba's dominant fatty acid components fall into this range. This ingredient may not be fungal acne safe.
Learn more about Simmondsia Chinensis Seed OilThis ingredient is also known as Apricot kernel oil, and it comes form the seed kernels of apricot (a member of the Rosaceae family like almond, peach, cherry, and plum).
It's mostly made up of triglycerides: oleic acid (43.9-78.5%), linoleic acid (9.7-37%), and palmitic acid (4.9-7.3%). These numbers vary depending on the variety of Prunus and the ripeness of the fruit; oleic tends to go up at late harvest while linoleic goes down.
Vitamin E is also prevalent in this ingredient and the most dominant form is gamma-tocopherol.
These compounds give the ingredient emollient and skin conditioning properties that keep the skin soft and hydrated.
There's no regulatory maximum cap for this ingredient so you'll see it across a huge concentration range (100% as a single ingredient facial oil).
On allergies: refined cosmetic-grade oils carry almost no protein. The CIR notes that people allergic to a food generally do not react to the refined oil because the allergenic protein does not partition into it (though cold-pressed grades retain more).
However, it's worth patch testing if you have a stone fruit or tree nut allergy because manufacturer processes for removing the protein can vary.
Malassezia lacks the cytosolic fatty acid synthase gene so the yeast cannot make palmitate on its own and instead uses lipases and phospholipases to release fatty acids from host lipids. Since apricot kernel oil is entirely C16-18 (right in the usable range of C11-24), this ingredient may not be fungal acne safe.
Old rabbit-ear testing did assign this ingredient a comedogenic rating of 1-2. The original author has stated that testing on rabbit ears is not an ideal model for human comedogenicity.
Human testing has proved that any finished product with a comedogenic ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin.
Just know high-oleic oils tend to feel heavier on oily skin so it's worth patch testing.
