Ingredients Explained

These ingredients are found in both products.

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

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, 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.

Abrasive, Emulsion Stabilising, Masking

Synthetic Wax is created from fossil fuels such as natural gas. It is used to enhance texture, adjust pH, and as an occlusive.

It may also be used as an abrasive ingredient to exfoliate the skin.

Synthetic Wax may not be fungal acne safe.

Polymethylsilsesquioxane is a silicone used as a film forming agent.

When applied to the skin, this ingredient creates an invisible film on the surface. This film still allows oxygen to pass through, but prevents moisture from escaping. This can help condition and hydrate the skin. It also leaves a silky feel when applied.

Polymethylsilsesquioxane has not been shown to clog pores. It has been deemed safe to use up to 55%, but most cosmetics use much less.

If you have concerns about using this ingredient, we recommend speaking with a professional.

Polybutene is used to help control the viscosity of a product. This just means it helps adjusts the texture.

It is a polymer and does not get absorbed into the skin due to its large size.

Studies found this ingredient did not irritate skin in concentrations below 15%.

Abrasive, Absorbent

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.

Emollient, Emulsifying, Skin Conditioning

Hydrogenated Castor Oil is created by adding hydrogen to castor oil. This helps stabilize the castor oil and raises the melting point. At room temperature, hydrogenated castor oil is solid.

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.

As a wax-like substance, Hydrogenated Castor Oil acts as an emollient. Emollients help keep your skin stay soft and smooth by creating a barrier. This barrier helps trap moisture.

Hydrogenated Castor Oil may not be fungal-acne safe. We recommend speaking with a professional.

Emulsion Stabilising

Synthetic beeswax is created to be identical in structure to beeswax. It possesses the same occlusive and emulsion properties.

A blend of fatty acid esters, fatty acids, and alcohols are used to create synthetic beeswax. Whether or not this ingredient is vegan depends on the source. Sometimes, lanolin is used for its creation.

This ingredient may not be Malassezia folliculitis, or fungal-acne safe.

Ethylene/Propylene Copolymer is an exfoliant.

Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (long name, huh?) is a synthetic antioxidant.

It is used to help stabilize other antioxidants or prevent the color from changing in a product.

As an antioxidant, it helps fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material. Thus, antioxidants may reduce the signs of aging.

This ingredient is oil-soluble.

Cosmetic Colorant

Ci 77499 is also hydrated iron III oxide. It is created from mixing red and black iron oxides. This helps give shades of darkness to a product.

Iron III oxides are classified as inorganic chemicals for coloring.

Cosmetic Colorant

This ingredient is used to impart a blue color. It is not water-soluble.

It goes by two different names: 1. Ferric Ferrocyanide: a synthetic dark blue pigment 2. Ferric Ammonium Ferrocyanide: a synthetic blue pigment, also called Prussian blue

In the EU, both of these colors must be labeled as 'CI 77510'.

I can't comment on the matte black as I immediately lost interest, but not before I tried the metallic champagne on my lower lash line. I was so disappointed! Despite all the hype on TikTok, it just didn't work out for me—the product tugged, was hard to blend, and clumped around my eyelashes. I found the formula more chunky glittery and not the subtle, shimmery effect I hoped for.
