Ingredients Explained

Emollient, Skin Conditioning

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.

Emollient, Skin Conditioning, Surfactant

Diisostearyl Malate is an emollient and most often used in lip products. It comes from isostearyl alcohol, a fatty acid, and malic acid, an AHA.

As an emollient, Diisostearyl Malate helps create a thin film on your skin to trap moisture in. This helps keep your skin soft and smooth.

Emollient, Masking

Octyldodecanol is a fatty alcohol sourced from plant oils like coconut or palm (or made synthetically).

It is:

You'll likely see this in many BHA products because this is the go-to solvent for salicylic acid.

This ingredient is typically used at levels between 2-20%.

Regarding fungal acne:
In 2019, this ingredient was tested against multiple Malassezia species (the yeast that causes fungal acne) and showed no growth.

Cleansing, Emulsifying, Surfactant

Isostearic Acid is a fatty acid and a structural cousin of stearic acid. It is an emulsifier.

The branched structure of this ingredient enhances fluidity and gives it a lighter, less greasy feel compared to other fatty acids. It helps improve texture and consistency because it prevents oil and water phases from separating.

This ingredient is sourced from plant-based oils like soybean or rapeseed.

Clinical studies found no signs of irritation from this ingredient.

Since Isostearic Acid is an 18-carbon fatty acid, it is in the range that Malassezia can feed on. This ingredient may not be fungal acne safe.

You might have seen sources that this ingredient is comedogenic. The original comedogenic testing on rabbit ear actually tested the ester, Isopropyl Isostearate and not Isostearic acid itself. There has been no comedogenic testing done on this ingredient, but it may be worth patch testing if you have acne-prone skin.

Emollient, Skin Conditioning

Bis-Diglyceryl Polyacyladipate-2 is a synthetic emollient that works as a lanolin substitute.

This ingredient is a great vegan option for those avoiding animal-derived ingredients.

It mostly stays on the surface of skin where it helps hydrate due to its large molecular size and low water solubility.

Due to it being derived from fatty acids, this ingredient may not be Malassezia or fungal acne safe.

Masking, Skin Conditioning

Caprylic/Capric Triglyceride (aka MCT Oil) is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping to prevent moisture loss.

Though it behaves like an oil, it is not technically one due to its chemical composition. One perk of this ingredient is that it is very stable, resistant to oxidation, and unlikely to go rancid.

In practice, that translates to a long shelf life and a consistently elegant skin feel.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Just patch test if you have concerns.

Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source.

This ingredient is treated as the gold standard fungal acne safe oil. Even though it is coconut derived, the problematic lauric acid is stripped out.

This leaves just caprylic (C8) and capric (C10) acid. These chain lengths actually trend antifungal; a 2020 study found caprylic acid was enough to disrupt Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%.

Masking, Skin Conditioning

Triethylhexanoin is created from glycerin and 2-ethylhexanoic acid. It is a solvent and emollient.

As a solvent, Triethylhexanoin helps dissolve ingredients to stable bases or help evenly distribute ingredients throughout the product.

It is also an emollient and helps condition the skin.

We don't have a description for Dibutyl Ethylhexanoyl Glutamide yet.

Antioxidant, Skin Conditioning

Tocopheryl 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.

Calcium Aluminum Borosilicate is made up of calcium, aluminum, and silicates. It is a glass-like material. In cosmetics, it comes in the form of flakes or microspheres.

Calcium aluminum borosilicate is a bulking agent, meaning it helps thicken a product.

This ingredient is created by slowly mixing several minerals, including kaolin clay.

Although “aluminum” in an ingredient name can raise red flags for some consumers, the form and usage context matter significantly. For typical topical applications, there is no substantial evidence of health risks - such as cancer, neurotoxicity, or systemic “aluminum overload.”

Preservative

Dehydroacetic Acid is a synthetic preservative that keeps your products safe from microbes.

As an organic acid, it penetrates microbial cell walls and disrupts cellular metabolism. This makes it effective against bacteria, yeast, and mold.

It is effective at low concentrations (<0.6%). Clinical studies have found it to be non-irritating, non-sensitizing, and non-photosensitizing.

Abrasive, Absorbent

Silica, also known as silicon dioxide, is a naturally occurring mineral. It is used as a fine, spherical, and porous powder in cosmetics.

Though it has exfoliant properties, the function of silica varies depending on the product.

The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer.

It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil.

In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients.

Cosmetic Colorant

Ci 77891 is a white pigment from Titanium dioxide. It is naturally found in minerals such as rutile and ilmenite.

It's main function is to add a white color to cosmetics. It can also be mixed with other colors to create different shades.

Ci 77891 is commonly found in sunscreens due to its ability to block UV rays.

Emollient, Skin Conditioning

Jojoba oil is one of the most well-studied plant-derived ingredients in cosmetics. It is an emollient with a special structure.

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.

Polyglyceryl-2 Triisostearate is a plant-derived emulsifier and pigment-dispersing agent with a non-sticky skin feel.

It helps products glide on smoothly and prevents oil and water from separating in a formula, making it suitable for sunscreen and makeup formulations.

The EU inventory of cosmetics has no use restrictions on this ingredient and it is considered well-tolerated.

This ingredient may not be fungal acne safe because it is derived from isostearic acid.

Cosmetic Colorant

CI 45410 is a synthetic red-pigment and dye.

It often goes by both Red 28 or Red 27; manufacturers label both ingredients as CI 45410.

This dye is commonly found in makeup because it imparts a vivid color. Some types of this dye change color based on pH level and interaction with moisture:

Your skin has a natural pH of around 4.5 - 5.5.

According to the FDA, CI 45410 is not permitted for use in eye products.

Red 27 is a flourescein dye and commonly used as a fluorescent tracer in medicine.

Abrasive

Tin Oxide is an inorganic oxide used to add opacity and volume to a product. In nature, it is already found in mineral form. The main ore of tin is an opaque and shiny mineral called casseterite.

Tin Oxide helps remove translucency in a product, or make it more opaque. Besides adding opacity, tin oxide is used for bulking to add volume.

Cosmetic Colorant

Ci 42090 is a synthetic dye created from petroleum. It is used to give a bright blue color to cosmetics, medicine, and food.

Skin Conditioning, Solvent

Water. 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!

Humectant, Skin Conditioning

Sodium 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.
