Ingredients Explained
Hydrogenated 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.

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 OilYou may know this ingredient as argan oil. It has emollient and skin conditioning properties that help soften skin and reinforce the lipid barrier.
The fatty acid profile of argan oil is roughly 45-55% oleic acid, 28-36% linoleic acid, 10-15% palmitic acid, and 5-7% stearic acid. It also contains vitamin E, sterols, squalene, and polyphenols like ferulic acid.
Two clinical studies in postmenopausal women found that applying argan oil for 60 days significantly improved skin elasticity and moisturization (reduced transepidermal water loss and increased epidermal water content).
Since it is high in oleic and linoleic acid, this ingredient may not be fungal acne safe. Both of these fall in the C11-C24 range that Malassezia yeast can metabolize.
Learn more about Argania Spinosa Kernel OilThis ingredient is more commonly known as Zhi Mu root. You might see this ingredient listed under 'Volufiline' products.
That's because 'Volufiline' is comprised of this ingredient and Hydrogenated Polyisobutene.
Zhi Mu root is rich in sarsasapogenin. This compound has anti-inflammatory and soothing properties.
It is commonly used in East Asian medicine.
Learn more about Anemarrhena Asphodeloides Root ExtractTocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.
One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.
Tocopheryl Acetate is commonly found in both skincare and dietary supplements.
Learn more about Tocopheryl AcetateWe don't have a description for Vanillyl Butyl Ether yet.
Adenosine is in every living organism. It is one of four components in nucleic acids that helps store our DNA.
Adenosine has many benefits when used. These benefits include hydrating the skin, smoothing skin, and reducing wrinkles. Once applied, adenosine increases collagen production. It also helps with improving firmness and tissue repair.
Studies have found adenosine may also help with wound healing.
In skincare products, Adenosine is usually derived from yeast.
Learn more about AdenosineThis ingredient is also known as olive oil. It has been used in skincare for centuries and science largely backs up its reputation as a nourishing emollient.
The main components of olive oil are oleic acid (55-83%), linoleic acid (3.5-20%), and palmitic acid (7-20%). Oleic acid promotes skin regeneration and helps regulate inflammatory responses.
Squalene is also naturally present in olive oil and exhibits moisturizing and antioxidant properties.
The polyphenols in olive oil also show anti-aging promise; one clinical study found a measurable improvement in skin appearance after 30 days of topical serum use.
Just be aware that applying olive oil directly to skin can weaken the barrier and cause redness. One study with volunteers found even people without sensitive skin experienced a significant reduction in stratum corneum integrity and induced mild erythema.
It's best to use this ingredient as part of a carefully crafted formula (instead of putting it on skin directly from the bottle).
Because it has a 2-3 on the comedogenic scale, it is a moderate risk for acne-prone skin. However, the overall formulation of a product matters more than a few ingredients with comedogenic ratings.
This ingredient may not be fungal acne safe because of the oleic and palmitic acid content. These fall within the C11-24 fatty acid range that the Malassezia yeast can metabolize to grow.
Overall, olive oil is a well-studied and nourishing skincare ingredient.
Learn more about Olea Europaea Fruit OilLimnanthes 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.
Learn more about Limnanthes Alba Seed OilCamellia Japonica Seed Oil comes from the Japanese Camellia plant. This plant is native to East Asia and known as "Tsubaki" in Japanese.
Camellia Japonica Seed Oil is rich in oleic acid. This makes it a great emollient. Emollients help soften and soothe the skin by forming a barrier. This barrier traps moisture within, keeping your skin hydated.
Hydrogenated Lecithin is a more stable version of lecithin.
It's made by taking lecithin (a phospholipid commonly found in soybeans and egg yolks) and hydrogenating it. This just means the unsaturated fatty acids are turned into saturated ones so they don't go bad as easily.
This ingredient is an emollient, emulsifier, and penetration enhancer. As an emollient, it helps soften and hydrate skin by trapping moisture within. As an emulsifier, it prevents oil and water ingredients from separating.
Hydrogenated Lecithin can form tiny spherical structures made of phospholipid bilayers called liposomes. These liposomes are able to capture compounds inside their structure and deliver them through the skin barrier.
Because phospholipids are a natural component of our cell membranes, this ingredient is inherently compatible with skin.
A 2021 study found lecithin-based surfactants were less harsh and more tolerable comared to Sodium Lauryl Sulfate (SLS).
Learn more about Hydrogenated LecithinGlycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Learn more about GlycerinPolyglyceryl-10 Oleate is made by combining ten units of glycerin with oleic acid.
According to a manufacturer, it is a low-irritation and hydrophilic (water loving) skin conditioning agent. It also improves the sensory feel and texture of a product.
Fungal acne note:
Since this ingredient is made from oleic acid, it might not be fungal acne safe. The Malassezia yeast survives by eating certain fats, including oleic acid.
However, it should be noted this oleic acid is chemically bound to a large polyglycerol molecule, so it might not trigger fungal acne for everyone.
Learn more about Polyglyceryl-10 OleateWater. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
Learn more about WaterDipropylene Glycol is a synthetically created humectant, stabilizer, and solvent.
This ingredient helps:
Dipropylene glycol is technically an alcohol, but it belongs to the glycol family (often considered part of the ‘good’ alcohols). This means it is hydrating and gentle on skin unlike drying solvent alcohols like denatured alcohol.
As a masking agent, Dipropylene Glycol can be used to cover the smell of other ingredients. However, it does not have a scent.
Studies show Dipropylene Glycol is considered safe to use in skincare.
Learn more about Dipropylene GlycolPhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Parfum 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.
