Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

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. Stay hydrated!

Learn more about Water
Emollient, Solvent

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.

Learn more about Isododecane
Abrasive, Absorbent, Skin Protecting

Talc 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 Talc

Magnesium Sulfate is a salt. It can be naturally found in sea water or mineral deposits.

In cosmetics, Magnesium Sulfate is used to thicken a product or help dilute other solids. It is a non-reactive and non-irritating ingredient.

You might recognize Magnesium Sulfate as epsom salt, or the bath salt used to help relieve muscle aches.

One study shows magnesium deficiency may lead to inflammation of the skin. Applying magnesium topically may help reduce inflammation.

Learn more about Magnesium Sulfate
Abrasive, Absorbent

Alumina is another name for the compound aluminum oxide. It is used as a thickener, absorbent, and abrasive.

As an absorbent, alumina can give a mattifying effect. It is used in mineral sunscreens to help coat nano-sized filters, such as titanium dioxide. By increasing the size of the UV filters, these ingredients stay on the skin for a longer time. By coating small sized ingredients, alumina helps thicken a product.

Alumina may be used as an abrasive, or exfoliant.

Alumina is naturally occurring in the mineral corundum. Certain varieties of corundum create rubies and sapphires. Corundum is also the crystalline form of alumina.

Emollient, Skin Conditioning, Skin Protecting

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 Dimethicone

This ingredient is a silicone used to improve the texture of products and absorb oil. It does not get absorbed into the skin.

Like other silicones, Dimethicone/Vinyl Dimethicone Crosspolymer helps condition the skin by creating a barrier. In this sense, it can act as an emollient and trap moisture in.

This ingredient is a solvent. It helps dissolve active ingredients and alter the texture of products.

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 Carbonate
Preservative

Potassium Sorbate is a preservative used to prevent yeast and mold in products. It is commonly found in both cosmetic and food products.

This ingredient comes from potassium salt derived from sorbic acid. Sorbic acid is a natural antibiotic and effective against fungus.

Both potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.

You'll often find this ingredient used with other preservatives.

Learn more about Potassium Sorbate
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.

Learn more about Tocopheryl Acetate

Triethoxycaprylylsilane is a silicone used to bind and stabilize ingredients.

As an emulsifier, it helps prevent ingredients from separating. This can help elongate the shelf life of products.

Triethoxycaprylylsilane is often used to coat mineral sunscreens ingredients to help give a better feel. It also helps reduce oxidative stress in sunscreens.

Learn more about Triethoxycaprylylsilane
Antioxidant, Masking, Skin Conditioning

Tocopherol (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 Tocopherol
Preservative

Phenoxyethanol 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.

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.

Learn more about CI 77891

This ingredient is a combination of red, black, and yellow iron oxide pigments. This combination of colors is usually found in foundation, because it results in a "skin" color.

for a no makeup makeup look, this is it. 20W wouldn’t work for me in a foundation, but this product is so light you don’t need an exact shade match.
