Ingredients Explained
Dimethicone 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 DimethiconePhenyl Trimethicone is a silicon-based polymer. It is derived from silica.
Phenyl Trimethicone is used as an emollient and prevents products from foaming.
As an emollient, it helps trap moisture in the skin. It is considered an occlusive.
Learn more about Phenyl TrimethiconeDimethicone Crosspolymer is a silicone created by modifying dimethicone with hydrocarbon side chains. Due to its large size, it does not penetrate skin. It is considered non-occlusive.
Dimethicone Crosspolymer is used to stabilize and thicken products. It also helps give products a silky feel.
This ingredient is a form of glycerin with emulsifying and emollient properties.
As an emulsifier, this ingredient helps keep products together while adding a thick texture. The manufacturer states this ingredient has emollient properties. Emollients help keep the skin hydrated by trapping moisture in.
Polyglyceryl-2 Triisostearate is created by reacting diglycerin and isostearic acid. Due to the isostearic acid base, it may not be safe for Malassezia or fungal acne.
Learn more about Polyglyceryl-2 TriisostearateSynthetic Fluorphlogopite is the synthethic version of mica. It consists of fluorine, aluminum and silicate.
Synthetic Fluorphlogopite is used to add volume to products.
It is considered non-irritating on the skin.
Learn more about Synthetic FluorphlogopiteRicinus Communis Seed Oil is the INCI name for castor oil.
Castor Oil helps moisturize the skin. It is rich in a fatty acid called ricinoleic acid. This fatty acid helps prevent moisture loss on the skin. This helps keep your skin soft and hydrated. Ricinoleic acid also has anti-inflammatory and pain reducing properties.
Besides hydrating the skin, castor oil is also used to hydrate hair. By keeping the hair shaft moisturized, breakage is decreased. More studies are needed to show castor oil's effective on stimulating hair growth.
Castor oil is created by cold-pressing castor seeds and then purifying the oil with heat. It was used in Ancient Egypt as fuel in lamps and to help treat eye irritation.
The term '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.
Learn more about Ricinus Communis Seed OilTribehenin comes from glycerin and behenic acid.
It is used as an emollient, or moisturizer. Emollients form a thin barrier on skin to prevent moisture from escaping.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
Learn more about TribeheninThis ingredient is a high molecular weight silicone. It has emulsifying and skin conditioning properties.
Mica refers to a group of silicate minerals. Mica crystals are easily split to give products a shimmer. These crystals are able to reflect light to temporarily give your skin a glowy look.
Mica is found to be safe. Trace amounts of heavy metals may be found in mica, but these metals are not harmful in our personal products.
Mica has been used since prehistoric times throughout the world. Ancient Egyptian, Indian, Greek, Roman, Aztec, and Chinese civilizations have used mica.
Mica can be naturally found throughout the world. However, some sources of mica may be controversial. In 2016, mica mined in the Jharkhand state in India was found to be using child labor. However, companies are able to source ethical mica affiliated with international organizations that monitor the mica supply chain.
Learn more about MicaThis 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 TriglycerideEthylhexyl Palmitate is created from 2-ethylhexyl alcohol and palmitic acid. It is a fatty acid ester.
The fatty acid content of Ethylhexyl Palmitate makes it an emollient. Emollients help soften and hydrate your skin by trapping moisture within.
Ethylhexyl Palmitate is also used to help improve the texture of cosmetics. It helps other ingredient dissolve in products and help disperse ingredients more evenly.
You'll likely find this ingredient in sunscreen, as it is often used to mix UV-blocking ingredients such as avobenzone and ethylhexyl triazone.
It can also help stabilize the fragrances in a product as a fragrance fixative.
Ethylhexyl Palmitate can be used to substitute mineral oil.
Due to its high fatty acid content, it may not be fungal-acne safe.
Learn more about Ethylhexyl PalmitateTocopheryl 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 AcetateAroma refers to an ingredient, or mixture of ingredients, that impart or mask a flavor.
The name is slightly confusing. This is because INCI associates aroma with flavor instead of smell.
Here is the official definition from the The International Cosmetic Ingredient Dictionary and Handbook:
“Aroma is a term for ingredient labeling used to identify that a product contains a material or combination of materials normally added to a cosmetic to produce or to mask a particular flavor.”
INCI shows the only purpose of aroma to be "flavouring".
However, due to regulation differences, some companies may use aroma in place of parfum.
In Canada, this ingredient only has to be listed in concentrations above 1%.

Propylene Carbonate is commonly used in makeup and with clay, such as montmorillonite or bentonite.
Studies show this ingredient to be safe for cosmetics. When it is undiluted, it can cause skin irritation. (It is always diluted in skincare and makeup). This ingredient is water-soluble.
Propylene Carbonate is created from propylene glycol and carbonic acid.
Learn more about Propylene CarbonateTocopherol (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 ingredient comes from Hydroxystearic Acid, a fatty acid, and glycerin. It is used to thicken oils.
Due to its fatty acid content, it is a natural emollient.
