Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
This ingredient comes from a palm tree native to Brazil. This ingredient is used to thicken texture and leaves behind a film when applied.
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.
The chemical name for this ingredient is 2,2,4,6,6-PENTAMETHYLHEPTANE.

Serecite is the name for very fine but ragged grains of mica.
This ingredient is often coated with metal oxides like titanium dioxide. 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.
Learn more about MicaPentaerythrityl 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.

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%.
Learn more about PolybuteneSynthetic beeswax is created to be identical in structure to beeswax without involving bees, making it a go-to for vegan formulas.
It's mainly used an an emulsion stabilizer and thickener.
This ingredient (alongside other synthetic waxes) have been concluded to be safe in cosmetics under the present practices.
Reported usage goes up to 18% and it is non-sensitizing.
Just one caveat for fungal acne: This ingredient is made up of C16-32 fatty acids and fatty acid esters. Part of this overlaps with the C11-24 range that the Malassezia yeast can feed on, so it's not fungal-acne safe.
Learn more about Synthetic BeeswaxSynthetic Wax is a manufactured hydrocarbon wax. In formulas, it works as an occlusive emollient that helps reduce water loss and improves the spreadability of products.
Research comparing synthetic wax to traditional mineral-derived products found that formulas containing it perform as well for skin hydration.
It is considered non-comedogenic and vegan-friendly.
This ingredient has a well-established safety record by the CIR Expert Panel for Cosmetic Ingredient Safety.
Synthetic Waxes are straight/branched-chain hydrocarbons with no ester bond or fatty acids. That means there is nothing for the Malassezia yeast to feed on.
