Ingredients Explained
Isododecane is a fragrance, emollient, and solvent.
As an emollient, it helps your skin stay soft and hydrated. Emollients help trap moisture into your skin.
Isododecane's role as a solvent makes it a great texture enhancer. It spreads smoothly on skin and does not leave a sticky feeling behind. Isododecane also helps prevent color transfer in makeup products.
Isododecane is not absorbed into skin.

Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.
Silica is present naturally within the skin during collagen production and when reducing inflammation.
Learn more about SilicaDextrin Palmitate comes from the palmitic acid ester of Dextrin. It is used as an emulsifier and texture enhancer.
Emulsifiers help keep ingredients together. According to a manufacturer, dextrin palmitate helps create a low-viscosity gel texture.
Due to its fatty acid base, this ingredient is not fungal-acne safe.
Learn more about Dextrin PalmitateHydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.
In one study, Hydrogenated Polyisobutene showed better skin hydration levels than Caprylic/Capric Triglyceride. As an emollient, it helps keep your skin soft and hydrated by trapping moisture in.
Hydrogenated Polyisobutene is often used as a mineral oil replacement.
Learn more about Hydrogenated PolyisobuteneTalc is a clay mineral. It helps absorb moisture and improve the texture of products. Like other types of clay, Talc can have a slight exfoliating effect on skin. Talc can be added to increase the volume of products.
Some Baby powders are made by combining talc with corn starch. The word "talc" comes from Latin and originates from Arabic. Talc is a mineral commonly found throughout the world.
If you have any concerns about using talc, we recommend checking out the FDA's official page.
Learn more about TalcParaffin is a solid created from petroleum. The term 'paraffin' can also refer to either
petroleum jelly or mineral oil.
It has natural occlusive properties which can worsen oily skin. Due to its petrolatum base, this ingredient is not fungal-acne safe.
Olea Europaea Fruit Oil is the fixed oil obtained from the ripe fruit of the Olive. In other words - olive oil.
The primary contents of olive oil are glycerides of the fatty acids linoleic, oleic and palmitic.
Olive oil also contains antioxidants such as Vitamin E. Antioxidants may help reduce signs of aging by fighting unstable free-radical molecules. It also contains Vitamins A (retinol), D, and K.
The squalene in olive oil makes it a great emollient. Emollients help soothe and soften your skin by trapping moisture in. This makes olive oil a great skin moisturizer.
Studies show olive oil to have antibacterial and antifungal properties in low concentrations. Another study found olive oil irritated sensitive oily skin. We always recommend speaking with a professional about using this ingredient in your routine.
Due to the fatty acid content, this ingredient may not be fungal-acne safe.

Learn more about Carthamus Tinctorius Seed OilButyrospermum Parkii Butter is a plant lipid from the fruit of the Shea Tree. It is an effective skin hydrator and emollient.
Emollients help soothe and soften your skin. It does this by creating a protective film on your skin. This barrier helps trap moisture and keeps your skin hydrated. Emollients may be effective at treating dry or itchy skin.
Shea butter is rich in antioxidants. Antioxidants help fight free-radicals, or molecules that may harm the body. It is also full of fatty acids including stearic acid and linoleic acid. These acids help replenish the skin and keep skin moisturized.
While Shea Butter has an SPF rating of about 3-4, it is not a sunscreen replacement.
Shea butter may not be fungal acne safe. We recommend speaking with a professional if you have any concerns.
Learn more about Butyrospermum Parkii ButterTocopherol (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.
Learn more about TocopherolThis 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.

Alcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol with other additives.
This ingredient gets a bad rep because it is irritating and drying - mostly due to its astringent property. Astringents draw out natural oils in tissue, constricting pores and leaving your skin dried out.
However, alcohol denat. is not all that bad.
Due to its low molecular weight, alcohol denat. tends to evaporate quickly. One study on pig skin found half of applied alcohol evaporated in 10 seconds and less than 3% stayed on skin.
This also helps other ingredients become better absorbed upon application.
Studies are conflicted about whether this ingredient causes skin dehydration. One study from 2005 found adding emollients to propanol-based sanitizer decreased skin dryness and irritation. Another study found irritation only occurs if your skin is already damaged.
Small amounts of alcohol are generally tolerated by oily skin or people who live in humid environments.
The rule of thumb is if this alcohol is near the end of an ingredients list, it will probably not affect your skin much.
Also...
This ingredient has antimicrobial and solvent properties.
The antimicrobial property helps preserve products and increase their shelf life. As a solvent, it helps dissolve other ingredients.
Other types of astringent alcohols include:

Disteardimonium Hectorite comes from the clay mineral named hectorite. It is used to add thickness to a product.
It can also help stabilize a product by helping to disperse other ingredients.
Hectorite is a rare, white clay mineral.
Learn more about Disteardimonium HectoriteDimethicone is a type of synthetic silicone created from natural materials such as quartz.
What it does:
Dimethicone comes in different viscosities:
Depending on the viscosity, dimethicone has different properties.
Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.
This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.
Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.
Learn more about DimethiconeThis silica is mainly used to thicken oils and suspend particles in oils. It is not water soluble.
According to the manufacturer, it:
The manufacturer also claims this ingredient to be useful in makeup.
In lipstick formulations, this ingredient improves color payoff, reduces pigment settling, and reduces oil bleeding. This ingredient also improves the grip of powder products such as dry shampoos.
Learn more about Silica Dimethyl SilylateSqualane 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.
Read more about squalene with an "e".
Is squalane an oil?
Squalane is often called an oil, but it’s technically not; it’s a hydrocarbon, meaning it’s only made of carbon and hydrogen, unlike true oils which are triglycerides 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.
While some people avoid oils thinking they cause breakouts, the right kind of oil (or oil-like ingredient like squalane) can actually help balance and hydrate your skin. It’s worth testing out simple oils or squalane to see what works best for your skin.
