Ingredients Explained
This ingredient is also known as cupuacu butter. It's a soft, creamy plant fat that works as a skin-conditioning agent and often marketed as the plant-based alternative to lanolin.
The composition of this butter is dominated by oleic acid, stearic acid, and smaller amounts of palmitic, linoleic, and arachidic acids. There's also a useful dose of phystosterols.
That fatty-acid-and-sterol combo is why this ingredient behaves like a richer cousin of shea butter: the lipids reinforce the skin's surface and slow water loss while the sterols help support the barrier.
There's some early research too: a mouse study found cupuacu butter emulgels had antioxidant activity and a measurable photoprotective effect against UVB damage.
Overall, this is a well-tolerated ingredient but those prone to congestion might prefer formulations with lower concentrations.
Fungal acne: Cupuacu butter's fatty acids are mostly "locked up" in triglycerides that Malassezia can't easily feed on, but the yeast can slowly break these down to access the free fatty acids. Therefore, ingredient may not be fungal acne safe.
Learn more about Theobroma Grandiflorum Seed ButterLimnanthes Alba Seed Oil is from the seeds of the meadowfoam plant. It is a skin conditioning agent and emollient that sits on top of skin to soften and hydrate it.
Over 98% of the oil is made up of long-chain fatty acids, mostly aachidic acid (61%), docosenoic acid (~16%), and docosadienoic acid (~18%).
This combination is not really found in any other plant oil and is the reason this is one of the most stable botanical oils available.
Some studies show it to be more stable than jojoba oil, helps a product resist going rancid, and can help extend the shelf life of a formula.
It also naturally contains vitamin E and phytosterols that give it a mild antioxidant benefit.
This ingredient is typically used from around 1% to fairly high levels since it's gentle; it's well-tolerated and low on the irritation scale.

Cera alba is beeswax, or the wax used by bees to make honeycombs. It is a texture-enhancer and emollient. A study from 2003 found beeswax to be a stronger emollient than ingredients such as petroleum jelly.
As an emollient, beeswax helps hydrate the skin by creating a barrier on top. This barrier traps moisture in.
Emulsifiers help prevent ingredients from separating. This helps create consistent texture.
The structure of beeswax is mainly long-chain alcohols and the esters of fatty acids.
There are three types of beeswax: yellow, white, and absolute. Yellow is pure beeswax taken from the honeycomb. White beeswax is created by filtering or bleaching yellow beeswax. Absolute beeswax is created by treating beeswax with alcohol. Beeswax used in cosmetics are purified.
Beeswax has been used throughout history and even in prehistoric times. Some common uses for beeswax still used today are making candles, as a waterproofing agent, and polish for leather.
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 Cera AlbaSodium 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.

Its dominant fatty acid is ricinoleic acid, giving it both emollient and mild humectant properties.
According to EU CosIng, this ingredient helps soften skin, keep oil and water stay mixed, and thickens products.
Hydrogenated castor oil at 30% did not trigger a positive patch-test reaction and is well-tolerated.
Since this ingredient is based on an 18-carbon fatty acid, it falls into the chain-length range that Malassezia can feed on and may not be fungal acne safe.
Learn more about Hydrogenated Castor OilThis 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.

Strawberry seeds contain fatty acids that are emollients. Emollients help hydrate and soften your skin.
Strawberries have antioxidant and hydrating properties. They contain many compounds that are potent antioxidants, such as anthocyanins and Vitamin C.
