Ingredients Explained
Macadamia Ternifolia Seed Oil is the fixed oil obtained from Macadamia nut.
Macadamia seed oil is rich in fatty acids, including oleic acid (45-75%), palmitoleic acid (7-33%), and palmitic acid (6-12%). They also contain various B vitamins, iron, and magnesium.
Palmitoleic acid has been shown to help soothe inflammation and promote wound healing. It is also naturally found in the fat of our skin.
Macadamia seed oil may not be malassezia folliculitis, or fungal-acne, safe.
Learn more about Macadamia Ternifolia Seed OilThis oil comes from the seeds of the desert shrub called Jojoba. It is more commonly known as jojoba oil, a non-comedogenic oil.
Jojoba oil does not contain fragrance and has many fatty-acids, making it a great soothing ingredient.
It also contains Vitamin E, a great moisturizing ingredient. Vitamin E is also an antioxidant and protects your skin against oxidative damage.
This ingredient humectant properties, meaning it helps draw moisture from the air. This helps keep your skin hydrated.
While jojoba has antibacterial properties, it is only able to kill some strains of bacteria.
Studies also show it helps in wound healing. In fact, Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.
Fun fact: Jojoba oil similar to natural human skin sebum, so it has a great effect on dry skin. It is also promising with helping to regulate sebum production.
Due to its fatty acid content, Jojoba oil may not be fungal acne safe. We recommend speaking with a professional if you have any concerns.
Learn more about Simmondsia Chinensis Seed OilThis ingredient is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.
It helps thicken a product's formula and makes it easier to spread by dissolving clumping compounds.
Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid.
While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this.
Learn more about Caprylic/Capric TriglycerideCarthamus tinctorius seed oil comes from safflower, one of humanity's oldest crops.
Safflower seed oil contains a high percentage of linoleic acid and oleic acid. It also contains Vitamin E. These three components are effective moisturizers.
Vitamin E helps nourish your skin's lipid barrier. It is also a potent antioxidant. Antioxidants help fight free-radical molecules, or unstable molecules that may damage your skin cells.
Due to its high fatty acid content, this ingredient may not be malassezia folliculitis safe.
Thoughout history, safflower has been used for dying fabrics and in food as a saffron substitute.
Learn more about Carthamus Tinctorius Seed OilIsoamyl Laurate is created from isoamyl alcohol and lauric acid. It is an emollient and traps moisture underneath.
This ingredient helps give products a silky feel and is considered a silicone alternative.
This ingredient may not be fungal acne safe.
Learn more about Isoamyl LaurateVitis 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 OilCamellia 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 OilSqualane is an emollient that helps the skin hold onto moisture. It's an oily liquid that occurs naturally in certain types of fish and plant oils.
Because squalane boosts hydration in the skin, it also comes with plenty of benefits: it is an antioxidant and can help fight free radicals and skin damage. Squalane is also found to have a detoxifying effect when applied.
Squalane comes from squalene, which occurs naturally within the sebum of our skin. It is one of the oils our skin produces to keep itself hydrated. Squalane is the hydrogenated version of squalene and has a longer shelf life.
Research shows that squalane is non-irritating (even at 100% concentration).
In general, it's a fantastic ingredient. It does a great job at hydrating the skin, and it's suitable for those with sensitive skin.
The source of squalane may impact malassezia / fungal acne. This is because olive oil derived squalane can contain impurities such as fatty acids and plant waxes. Sugarcane derived squalane is recommended for anyone with malassezia concerns.
Is squalane vegan?
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.

Learn more about SqualaneBaobab seed oil is an emollient. It is rich in fatty acids and vitamins A, E, and D.
The fatty acid content of this oil is roughly 30-40% oleic acid, 24-34% linoleic acid, and 18-30% palmitic acid. This gives it skin hydrating and nourishing properties.
Due to this fatty acid content, this ingredient may not be fungal-acne safe.
Fun fact: Our skin uses fatty acids, and especially linoleic acid, for creating ceramides.
Learn more about Adansonia Digitata Seed OilParfum is a catch-all term for an ingredient or more that is used to give a scent to products.
Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.
The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Parfum can also be used to mask or cover an unpleasant scent.
The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
Learn more about ParfumTocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

Marula seed oil is a non-fragrant oil. It is rich in fatty acids, such as oleic, linoleic, palmitic, stearic, and more. These fatty acids help hydrate the skin.
Other components of marula seed oil include vitamin E and antioxidants such as flavonoids.
Due to the fatty acid content, this ingredient may not be fungal-acne safe.
Learn more about Sclerocarya Birrea Seed OilHippophae Rhamnoides Seed Oil comes from the seeds of the seabuckthorn plant.
Seabuckthorn is rich in phytosterols, carotenoids, Vitamins A, C, and E. This gives it strong antioxidant properties that can help soothe and protect your skin from oxidative damage.
The seeds of seabuckthorn are rich in fatty acids. These include linoleic acid (~30-34%), oleic acid (17%), and palmiteic acid (35%).
Palmitoleic acid has been shown to help soothe inflammation and promote wound healing. It is also naturally found in the fat of our skin.
Learn more about Hippophae Rhamnoides Seed OilHelianthus Annuus Seed Oil is the oil derived from the seeds of a Sunflower. Sunflower seed oil is non-fragrant. It is an emollient, meaning it helps to soften the skin.
Sunflower seed oil contains many fatty acids. The fatty acids found in sunflower seeds include (from highest amount to least): linoleic acid, myristic acid, palmitic acid, stearic acid, arachidic acid, oleic acid, and linolenic acid.
These fatty acids help the skin create ceramides. Ceramides play a role in repairing the skin barrier.
Helianthus Annuus Seed Oil helps moisturize the skin. This in turn helps the skin look more rejuvenated and smoother.
Sunflowers are rich in vitamin E.
Historians believe Indigenous cultures of North America domesticated sunflowers before corn. Thus they relied on sunflower oil for a variety of uses. One such use is moisturizing skin and hair.
Sunflower seed oil may not be fungal acne safe. We recommend speaking with a professional if you have any concerns.
Learn more about Helianthus Annuus Seed OilEthyl Linoleate is a fragrance and isn't fungal acne safe.
Ascorbyl Tetraisopalmitate is a version of ascorbic acid, or pure Vitamin C.
This ingredient has many benefits including reducing wrinkles, skin soothing, dark spot fading, and fighting against free radicals.
It helps with dark spot fading by interfering with the process of skin darkening, helping to reduce hyperpigmentation. Like other forms of vitamin C, this ingredient encourages the skin to create more collagen.
As an antioxidant, it helps fight free-radicals. Free-radicals are molecules that may damage your skin cells.
One study found Ascorbyl Tetraisopalmitate to degrade in sunlight, but is stabilized when combined with acetyl zingerone.
Learn more about Ascorbyl TetraisopalmitateCananga Odorata Flower Oil comes from the ylang-ylang flower, Cananga odorata.
Ylang-ylang oil has slight antibacterial, antioxidant and antifungal properties. However, it also contains a number of sensitizing ingredients such as geraniol, limonene, linalool and benzyl benzoate. These compounds are known EU allergens.
The composition of this ingredient depends on the source. Luxury perfumes tend to use higher grade ylang-ylang for their fragrance. Lower grade ylang-ylang is less fragrant.
Learn more about Cananga Odorata Flower OilVaccinium Macrocarpon Seed Oil is created from the seeds of the North American cranberry plant. This plant is native to eastern Canada.
Cranberry seed oil has antioxidant, anti-inflammatory, and hydrating properties.
Due to its high linolenic acid, linoleic acid, and oleic acid content, cranberry seed oil is an effective emollient. Emollients help hydrate the skin by creating a film on the skin. This barrier prevents moisture from escaping. Linolenic acid also has anti-inflammatory properties.
Cranberry seeds also contain Vitamin E and Vitamin C, both potent antioxidants.

Benzyl Salicylate is a solvent and fragrance additive. It is an ester of benzyl alcohol and salicylic acid. This ingredient can be naturally found in some plants and plant extracts.
In fragrances, Benzyl Salicylate may be a solvent or a fragrance component. In synthetic musk scents, it is used as a solvent. For floral fragrances such as lilac and jasmine, it is used as a fragrance component. The natural scent of Benzyl Salicylate is described as "lightly-sweet, slightly balsamic".
While Benzyl Salicylate has been associated with contact dermatitis and allergies, emerging studies show it may not be caused by this ingredient alone.
However, this ingredient is often used with fragrances and other components that may cause allergies. It is still listed as a known allergen in the EU. We recommend speaking with a professional if you have concerns.
Another study from 2021 shows Benzyl Salicylate may have anti-inflammatory properties.
Learn more about Benzyl SalicylateCitronellol is used to add fragrance/parfum to a product. It is often derived from plants such as roses. In fact, it can be found in many essential oils including geranium, lavender, neroli, and more. The scent of Citronellol is often described as "fresh, grassy, and citrus-like".
Since the Citronellol molecule is already unstable, Citronellol becomes irritating on the skin when exposed to air.
Citronellol is a modified terpene. Terpenes are unsaturated hydrocarbons found in plants. They make up the primary part of essential oils.
Citronellol is not able to be absorbed into deeper layers of the skin. It has low permeability,
