Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
This ingredient is lipid-based synthetic skin-conditioning agent derived from adipic acid and a mixture of fatty acids. It is often called a lanolin substitute.
As an emollient, it helps soften and hydrate the skin. Emollients create a barrier on the skin to trap moisture in.
Due to its fatty acid base, it may not be Malassezia folliculitis safe.
Learn more about Bis-Diglyceryl Polyacyladipate-2This pigment is called Ultramarine blue lazurite. It gives a saturated blue color, but can be used to create other colors as well.
According to the manufacturer, it is usually made from kaolin, sodium sulfate, sodium carbonate, sulfur, and charcoal.
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'.

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.

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.
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.

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 PolybutenePolyethylene is a synthetic ingredient that helps the skin retain moisture. It is a polymer.
It is also typically used within product formulations to help bind solid ingredients together and thicken oil-based ingredients. When added to balms and emulsions, it helps increase the melting point temperature.
Synthetic 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.
It has a well-established safety record by the CIR Expert Panel for Cosmetic Ingredient Safety.

The EU typically uses CI numbers for colorants when applicable, such as CI 77489. In the US, iron oxides are regulated as color additives and "iron oxides" is the most commonly used name in US cosmetic practice.
A 2021 paper looked at skincare formulations containing iron oxides and found that they reduced transmission of blue light when measured optically. In simple terms, the pigment particles helped block or scatter part of the visible light spectrum in lab testing and the authors suggest this could translate into better protection against blue-light-related skin effects.
There is also clinical and experimental research showing that tinted products containing iron oxides can reduce visible light-induced pigmentation:
Please note, whether a product reduces visible or blue light depends on things like:
In the EU's CosIng database, iron oxides are only listed as a colorant. CosIng groups ingredients by their main cosmetic role, such as colorant, preservative, or UV filter.
Though studies say iron oxides can "attenuate blue light", they're describing an optical property and not an officially recognized cosmetic function.
So CosIng isn’t contradicting the research. It’s just classifying iron oxides by what they officially are: pigments that add color.
