Ingredients Explained
This 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 OilCaprylic/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 TriglycerideEuphorbia Cerifera Cera (aka candelilla wax) is a vegan stand-in for beeswax. It is a plant-derived wax that functions as an astringent, emulsion stabilizer, film-former, and skin conditioner.
On skin, it forms a protective barrier that helps lock in moisture while it enhances product stability, prevents separation, and helps color last longer in makeup.
This ingredient is generally safe for use in cosmetics with one nuance: some grades of candelilla wax can naturally contain benzyl alcohol at concentrations high enough to require declaration under EU labeling rules. This isn't a concern for most people but relevant for those with fragrance sensitivities.
Candelilla wax contains fatty acids (mainly C31) and wax esters that can be used by the Malassezia yeast, so this ingredient may not be fungal acne safe.
You might see Euphorbia Cerifera "Wax" instead of "cera". This is because some brands, databases, or labels use it interchangeably; they're the same ingredient.
Learn more about Euphorbia Cerifera CeraBis-Diglyceryl Polyacyladipate-2 is a synthetic emollient that works as a lanolin substitute.
This ingredient is a great vegan option for those avoiding animal-derived ingredients.
It mostly stays on the surface of skin where it helps hydrate due to its large molecular size and low water solubility.
Due to it being derived from fatty acids, this ingredient may not be Malassezia or fungal acne safe.
Learn more about Bis-Diglyceryl Polyacyladipate-2Mica is a naturally occurring mineral used to add shimmer and color in cosmetics. It can also help improve the texture of a product or give it an opaque, white/silver color.
Serecite is the name for very fine but ragged grains of mica.
This ingredient is often coated with metal oxides like titanium dioxide. Trace amounts of heavy metals may be found in mica, but these metals are not harmful in our personal products.
Mica has been used since prehistoric times throughout the world. Ancient Egyptian, Indian, Greek, Roman, Aztec, and Chinese civilizations have used mica.
Learn more about MicaSilica, also known as silicon dioxide, is a naturally occurring mineral. It is used as a fine, spherical, and porous powder in cosmetics.
Though it has exfoliant properties, the function of silica varies depending on the product.
The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer.
It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil.
In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients.
Learn more about SilicaOctyldodecanol is a fatty alcohol sourced from plant oils like coconut or palm (or made synthetically).
It is:
You'll likely see this in many BHA products because this is the go-to solvent for salicylic acid.
This ingredient is typically used at levels between 2-20%.
Regarding fungal acne:
In 2019, this ingredient was tested against multiple Malassezia species (the yeast that causes fungal acne) and showed no growth.
Lanolin oil is the liquid part of lanolin, or the waxy grease that sheep product to waterproof their wool.
Raw lanolin is a thick, sticky solid so manufactures chill and fractionate it to separate the hard waxy part from the pourable oil portion.
What's left is lanolin oil, and it's a light, non-greasy emollient that sits on skin, slows water loss, and softens rough patches.
Chemically, it's mostly wax esters plus some fatty acids where the majority are branched (making it structurally closer to human sebum than most plant oils).
A 2022 industry survey found lanolin oil has the highest maximum-leave on concentration of any lanolin ingredients (47% in lipsticks and the permitted range for lanolin in US OTC producrts is 12.5-50%).
The concentrations are much lower in actual face products, often between 1-10%.
Lanolin ingredients are found safe at current use levels by the Cosmetic Ingredient Review Expert Panel.
Lanolin has a reputation as pore clogging but that comes almost entirely from rabbit ear testing done decades ago (and that model has aged badly).
This ingredient does have a comedogenic rating of 0-1; the tests state this score means the ingredient has low or non-existent chance of clogging your pores.
Keep in mind that the authors of the rabbit ear test proposed that a material needs to score consistently above 3 in the rabbit assay before it means anything for real skin.
A separate review found the model has serious performance problems and no correlation with human experience. Concentration matters a lot too: in one study, Acetylated Lanolin Alcohol scored 4 to 5 at full strength but dropped to a 1 when diluted to 2.5%, and finished products containing "comedogenic" ingredients didn't raise microcomedone counts in people.
Since this ingredient is build with exactly the esters that Malassezia yeasts can synthesize, this ingredient may not be fungal acne safe.
Learn more about Lanolin OilJojoba Esters is a wax created from Jojoba oil. It is an emollient and film-forming ingredient. In bead form, it is an exfoliator.
This ingredient has high oxidative stability, meaning it doesn't break down when exposed to oxygen.
Its similarity to our skin's natural oils makes it a great emollient. Emollients help soften and soothe our skin by creating a barrier on top. This barrier helps trap moisture in, keeping skin hydrated.
It is created using either the hydrogenation or transesterification processes on jojoba oil.
Learn more about Jojoba EstersPentaerythrityl Tetraethylhexanoate is an emollient that helps make your skin smooth and hydrated. It specializes in creating a non-oily and "wet" feeling on skin.
This ingredient comes from isostearic acid, a saturated fatty acid. It is a synthetic ingredient.
Helianthus Annuus Seed Cera isn't fungal acne safe.
Beeswax is natural wax produced by honey bees to build their honeycomb.
Because it forms a protective layer on your skin, it can help lock in moisture and reduce water loss. It is also widely used as a thickener and emulsifier in lip balms and lotions. Research suggests beeswax containing moisturizers can support skin barrier integrity.
In comedogenic testing, Beeswax scored a 0-2, which is on the low end. Whether or not a product clogs your pores really comes down to the formula as a whole (not any single ingredient on its own) and your skin.
Cera Alba is the white, bleached form of this ingredient.
Just so you know, beeswax is not vegan since it is animal-derived. It cannot be removed with water, but can be taken off with an oil cleanser.
People with a known Propolis allergy also report to have reactions from beeswax.
Beeswax's wax esters are derived primarily from palmitic and oleic acid (C16 and C18:1). Both of these fall within the C11-C24 feeding window.
The Malassezia yeast can potentially cleave these esters and release usable fatty acids, so this ingredient may not be fungal acne safe. However, not everyone will react to this ingredient.
Learn more about BeeswaxCopernicia Cerifera Wax comes from a palm tree native to Brazil; another name for this ingredient is Carnauba Wax.
This ingredient is used to thicken texture and also leaves behind a film when applied.
Fun fact: This wax has the highest melting point of all natural waxes and low solubility.
Learn more about Copernicia Cerifera WaxCamellia Oleifera Seed Oil comes from a green tea plant native to China. It is closely related to Camellia sinensis. Both plants have very similar properties. This plant also has similar properties to olive oil.
This ingredient is rich in oleic acid. This makes it an effective moisturizer. By creating a thin film on the skin, Camellia Oleifera Seed Oil traps moisture within. This helps keep your skin smooth and hydrated.
The antioxidant and soothing properties of this ingredient come from Vitamin E and polyphenols.
The seed oil comes from the dried kernels of the plant.
Learn more about Camellia Oleifera Seed OilThis ingredient is also known as Cocoa butter; it's the fat pressed out of roasted cocoa beans.
Cocoa butter is solid at room temperature and melts right around body temperature, which is why it feels waxy in the jar and slippery on skin.
It has a very saturated profile (stearic acid ~34 to 36%, oleic acid ~30 to 40%, and palmitic acid ~24 to 29%) that makes it a strong occlusive: it sits on top and slows water escaping from skin.
Concentration data shows that it can show up anywhere from a few percent in lotions up to 100% in balms, and the FDA lists cocoa butter as an OTC skin protectant active at 50-100%.
The CIR has reviewed it and concluded it to be safe as used in cosmetics.
This is one of the ingredients with a comedogenic score of 4/5 from the rabbit ear test. Just know that a later human study did find that finished products containing high-comedogenic ingredients like cocoa butter did not increase microcomedone formation.
The fair call here is that this ingredient is most likely fine on body or low-percentage formulas, but can potentially be riskier as a heavy leave-on facial product if you break out easily.
Cocoa butter may not be fungal acne safe; it is a triglyceride of C16-18 fatty acids that the Malassezia yeast can metabolize.
Allergies to cocoa butter are rare and uncommon, but a few cases have been documented (mostly in cases where the person ate chocolate). So if you have a tree nut allergy, be sure to patch test or avoid.
Learn more about Theobroma Cacao Seed ButterVitis 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 OilAcacia Decurrens Flower Cera isn't fungal acne safe.
This ingredient is also known as shea butter. It is a plant-derived extract from the nuts of the Africa shea tree and one of the most well-studied emollients.
Because it has a high concentration of fatty acids (primarily oleic, stearic, and linoleic) it is able to form a protective barrier on the skin's surface. This helps seal in moisture and prevents transepidermal water loss (TEWL).
In vitro research found an increase in skin hydration by 58% and a decrease in TEWL by 37.8% after 24 hours of applying this ingredient (pretty impressive for a single ingredient!).
Besides hydration, shea butter also contains triterpenes that have anti-inflammatory potential. In particule, lupeol cinnamate has shown the highest anti-inflammatory activity in vivo.
Shea butter also contains vitamins A and E which may contribute to antioxidant activity.
While Shea Butter has an SPF rating of about 3-4, it is not a sunscreen replacement.
This ingredient may not be fungal acne safe because its fatty acids fall within the C11-C24 range that the Malassezia yeast can metabolize.
This ingredient shows up on a lot of "pore-clogging" lists but there's no real evidence behind that. It doesn't even have a comedogenic rating from an actual study; the numbers you'll find online come from blogs citing other blogs.
Ratings for other ingredients mostly come from a 1980s rabbit ear test. This test doesn't translate well to human skin or to real products because the ingredient sits at a much lower percentage.
Some people still find it breaks them out. So if that's you, definitely trust your skin. Just know this one's based on experience and not evidence.
Learn more about Butyrospermum Parkii ButterCaprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.
Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.
Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).
Learn more about Caprylyl GlycolCarthamus Tinctorius Seed Oil comes from the seeds of the safflower plant. It is a skin conditioning agent that helps soften skin and keep it hydrated.
This seed oil has an unusual fatty acid profile: it is one of the highest linoleic acid plant oils out there (~55-77%). It also has low amounts of oleic acid, and this high-linoleic/low-oleic ratio gets people excited.
Linoleic acid helps maintain skin barrier integrity and is a building block for the ceramides in your stratum corneum. Notably, people with acne tend to have lower linoleic acid in their skin lipids as well (and this gets worse as acne gets more severe).
Overall, it's a lightweight, fast-absorbing oil that has a long safety track record. Lab testing has found it to be non-irritating for skin or eyes.
The Malassezia yeast can metabolize the fatty acids in this oil to grow; therefore this ingredient may not be fungal acne safe.
Learn more about Carthamus Tinctorius 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 PalmitateEthylhexylglycerin is created from glycerin. It is a multitasker ingredient that:
The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.
Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.
Learn more about EthylhexylglycerinGlucomannan is a fiber created from the Konjac plant. It is an emulsifier and thickener.
The high polysaccharide content makes it great at adjusting the texture of products. (Kind of like starch).
Polysaccharides also help our skin stay hydrated.
This ingredient is water-soluble.
Learn more about GlucomannanHelianthus Annuus Extract comes from the common sunflower.
Sunflowers are rich in vitamin E. Studies show sunflowers contain antimicrobial and antioxidant properties.
The fatty acids found in sunflowers include (from highest amount to least): linoleic acid, myristic acid, palmitic acid, stearic acid, arachidic acid, oleic acid, and linolenic acid.
These fatty acids hydrate your skin. Emollients create a film on the skin to prevent moisture from escaping.
Learn more about Helianthus Annuus ExtractThough this ingredient might sound like a juicy fruit extract, it's actually the fat pressed from the mango seed kernel (or the pit).
In skincare, it behaves more like shea butter and cocoa butter than like a plant active.
The fatty acid makeup of mango seed butter makes it special; it's typically rich in stearic acid and oleic acid, with small amounts of palmitic and linoleic acid.
This combo helps it melt on skin, feel creamy, and leave behind a protective "seal" that slows down water loss.
It also contains a small amount of "extras" like tocopherols (vitamin E) and phytosterols, which are often used to support skin soothing.
Due to its fatty acid content (like oleic acid), this ingredient may not be fungal acne safe. In vitro studies have shown that Oleic Acid is one of the fatty acids that induce rapid Malassezia growth in lab settings.
Learn more about Mangifera Indica Seed ButterThis ingredient is the essential oil from the leaves of cornmint. It is one of the richest natural sources of menthol on our planet (about 70-78%).
In cosmetics, this ingredient mostly works as a fragrance and/or masking agent used to cover up unpleasant smells of other ingredients.
The "cooling" sensation from mint isn't a real temperature change; menthol actives a nerve receptor in skin that gets triggered by cold. Your brain essentially gets a "cool" signal from it.
Just so you know, allergic contact dermatitis to menthol is documented in literature (but it's kind of uncommon). This is why the percentages allowed in leave-on products are quite low (0.2%). Be sure to patch test if you have sensitive skin.
Though this ingredient is not listed as an EU allergen, it's cousins (Mentha Piperita Oil, menthol and Mentha Viridis Leaf Oil) are.
Due to the high Menthol content of this ingredient, brands are required to label "menthol" as a separate ingredient on the list. The EU regulation labels the allergenic substance, not just the source ingredient, so the menthol carried in this ingredient still has to be declared.
Learn more about Mentha Arvensis Leaf OilOryza Sativa Bran Extract comes from the outer layer of a rice kernel. It is a byproduct of milling rice, or the operation to produce a whole grain rice product.
This ingredient has moisturizing properties due to its components of polysaccharides and omega-3 fatty acids. It also contains calcium, selenium, phosphorus, iron, and zinc.
Oryza Sativa Bran Extract contains numerous antioxidants such as ferulic acid. Antioxidants help fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material.
Learn more about Oryza Sativa Bran ExtractThis ingredient is also known as Avocado oil. It's the cold-pressed oil from the flesh of the avocado fruit packed with fatty acids (mostly oleic acid).
The rich fatty acid profile allows it to function as a skin conditioning agent and emollient; it helps soften and smooth skin while reducing water loss.
Preclinical research has found that topical avocado oil increased collagen synthesis and reduced inflammation during wound healing, giving it some skin-repairing credibility.
The unsaponifiable fraction of the oil is also interesting: studies on avocado unsaponifiables showed that it helped skin produce more collagen and other structural compounds that support healing.
The CIR Expert Panel has found this ingredient to be non-irritating in formulations.
This ingredient may not be fungal acne safe. This is because the oleic acid content falls within the range that Malassezia can use as a food source.
This ingredient does have a comedogenic rating of 0-3, 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 Persea Gratissima OilPolyglycerin-3 is a 3-unit glycerin polymer.
Like glycerin, this ingredient is a humectant. Humectants help hydrate your skin by drawing water to it.
Having moisturized skin helps improve the skin barrier. Your skin barrier helps protect against irritants and bacteria.
Learn more about Polyglycerin-3Rosa Canina Fruit Oil is a non-fragrant plant oil that has earned its skincare reputation through chemistry.
It's dominated by fatty acids like linoleic acid (~35-55%), alpha-linolenic acid (~17-27%), and oleic acid (~14-22%). This is the exact profile that supports skin barrier, locks in hydration, and calms inflammation.
A 2024 review found evidence for the Rosa canina species supports its use for scarring, hyperpigmentation, wrinkles, and atopic dermatitis; this was mostly credited to its vitamin C content and fatty acid composition as the primary active mechanisms.
You might see this ingredient marketed as a "natural retinol". Some rosehip seed oils contains traces of all-trans-retinoic acid but these trace amounts are far below biologically active levels.
The Cosmetic Ingredient Review Panel has deemed this ingredient safe and it's well-tolerated.
Fungal acne: The fatty acids of this oil fall into the C11-24 range that Malassezia yeast can metabolize, so this ingredient may not be fungal acne safe.
Learn more about Rosa Canina Fruit OilThis is a botanical extract from the rosemary plant (the same one you cook with). In skincare, it mostly works as a skin conditioning agent.
Its activity comes from a handful of polyphenols, carnosic acid, carnosol, and rosmarinic acid. Almost 90% of the antioxidant activity of this ingredient can be attributed to canosol and carnosic acid.
These compounds protect your skin two ways:
1) They fight off free radicals, or the unstable molecules from things like sun and pollution that age and damage skin.
2) They help calm inflammation by switching off the chemical signals that tell skin to get red and irritated.
Lab studies also suggest that rosmarinic acid may help protect collagen and slow sugar-related damage to it.
The Cosmetic Ingredient Review has concluded rosemary-derived ingredients to be safe when formulated to be non-sensitizing.
Rosemary can occasionally cause allergic contact dermatitis (due to carnosol), so be sure to patch test if you have reactive or fragrance-sensitive skin.
Learn more about Rosmarinus Officinalis Leaf ExtractJojoba 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 OilSodium Hyaluronate is the salt form of hyaluronic acid. It is a long sugar chain that is naturally found in your skin, joints, and connective tissue that maintains hydration and elasticity.
In skincare, it works as a humectant. It pulls water from the environment and deeper layers of skin and binds it to the surface.
Interestingly, the size of the molecule affects its behavior:
Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.
Many serums use a blend of both weights so you can get surface hydration plus longer-lasting and deeper effects.
You'll typically see concentrations between 0.1-2% for this ingredient.
Learn more about Sodium HyaluronateTocopherol is a fat-soluble antioxidant known as Vitamin E.
You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.
Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.
It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.
This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.
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.
In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.
Concentrations usually range from 0.1-1% in most leave-on products.
Learn more about TocopherolTocopheryl 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 AcetateTrihydroxystearin is what you get when you fully hydrogenate castor oil into a waxy, fine powder.
It's mostly a behind-the-scenes texture enhancer that's especially good at "thixotropic" thing where the product stays thick but applies nicely.
Because of its structure, it also acts as a mild skin conditioning emollient that helps soften skin while preventing moisture loss.
Safety studies show it to be safe and non-irritation in clinical tests. It's typically used in concentrations up to 5%.
Since its an ester of a C18 fatty acid, it falls into the C11-24 range that Malassezia can potentially feed on. This makes it not fungal-acne safe.
Learn more about TrihydroxystearinLimonene is the compound that gives citrus peel its smell.
In skincare, it shows up as a standalone fragrance ingredient or as a natural compound of citrus and other essential oils.
You'll typically see this ingredient used in very small amounts; anything above 0.001% in a leave-on product or 0.01% in a rinse-off has to be named on the label in the EU. The citrus oils that carry it sit around 0.5-1% in a finished formula.
Fresh limonene is a weak allergen; the real issue is that it slowly reacts with air and then breaks down from oxidation to create hydroperoxides (which are strong sensitizers). This is why suppliers are required to keep the peroxide value below 20 mmol.
Positive reactions in people being investigated for eczema vary:
It's worth skipping if you have a known fragrance allergy or a compromised barrier, but the risk is low for most people.
