Ingredients Explained
Shorea Stenoptera Seed Butter isn't fungal acne safe.
This 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.
Learn more about Prunus Armeniaca Kernel OilThough 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 ButterMurumuru butter is a solid fat pressed from the seeds of an Amazonian palm.
It's a bit unusual among plant butters due to its fatty acid profile: it's roughly 47% lauric acid (C12) and 26% myristic acid (C14), with about 13% oleic, 6% palmitic, 3% linoleic and 3% stearic acid.
Those are medium-chain fats which is why it melts fast on skin and feels lighter than stearic-heavy butters like shea or cacao.
In skincare, this butter works as an emollient and a temporary occlusive that helps soften the skin's surface and slows water loss.
Just to be upfront: there's no published human clinical trials on this ingredient and everything known about how it behaves on skin is from the fatty acid composition + general body of data on refined plant oils. At this time, marketing claims about wrinkles, elasticity, or "deep repair" are unsupported.
Industry survey data shows concentrations between 0.001%-7% for leave-on products and rinse-off products are capped around 0.2%.
No one has tested murumuru butter for comedogenicity in humans; the comedogenic ratings floating around trace back to lauric and myristic acid scores from the 1984 rabbit ear assay.
The author of that study later said that testing on rabbit ears is not ideal and human testing found that comedogenic ratings cannot predict how a finished formula will behave. It all comes down to formula, concentration, and your skin.
Malassezia is lipid dependent and feeds on free fatty acids between C11-24 chain lengths. This ingredient is made up entirely of chains in that range, so it may not be fungal acne safe.
Learn more about Astrocaryum Murumuru Seed ButterThis ingredient is also known as oat kernel oil. It's an emollient and skin conditioning agent that is great for barrier support, hydrating skin, and calming irritation.
The fatty acid profile is dominated by linoleic acid (~22.8-43.1%), oleic acid (~31.4-51.3%), and palmitic acid (~13.9-18.8%).
Plus, it contains ceramides, phytosterols, phospholipids, vitamin E, and avenanthramides (oat's signature anti-inflammatory polyphenols).
One study found an oat lipid extract applied to human skin cells switched on receptors that tell skin cells to mature properly and make more barrier lipids (including a 70% boost in ceramides).
Basically, oat kernel oil doesn't just sit on top of skin, it nudges your skin to build more its of its own barrier.
Typical usage levels range from 1-10%.
Note: This ingredient may not be fungal acne safe due to the fatty acids present.

Euphorbia 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.

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.
