Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
We don't have a description for C20-40 Alcohols yet.
Ci 75470 is a bright-red pigment. It is AKA carmine.
Carmine is derived from insects such as the cochineal beetle. This ingredient has been used as a natural dye for over 2000 years.
We don't have a description for CI 77000 yet.
This 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'.
Learn more about CI 77510Ci 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 77891Cyclopentasiloxane, or D5, is a silicone used to improve texture of products and trap moisture.
D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.
It is also an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.
Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.

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.
Learn more about IsododecaneMica is a naturally occurring mineral used to add shimmer and color in cosmetics. It can also help improve the texture of a product or give it an opaque, white/silver color.
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 MicaNylon-12 is a polymer. It is derived from 12-aminododecanoic acid, an omega-amino fatty acid
According to a manufacturer, it is a talc substitute. Like talc, nylon-12 gives products a satin feel. The manufacturer also claims this ingredients does not block pores and has moderate oil absorption.
This ingredient may not be reef-safe.

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.

Polyethylene 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.
This ingredient is a water-in-oil emulsifier and is sometimes known by its trade name, Isolan GPS. It helps create stable emulsions by bridging oil and water phases without adding a greasy feel.
Common usage levels sit between 2-5% for this ingredient.
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.
Learn more about Synthetic WaxTocopherol is a fat-soluble antioxidant known as Vitamin E.
You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.
Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.
It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.
This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.
This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.
In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.
Concentrations usually range from 0.1-1% in most leave-on products.
Learn more about TocopherolThis 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.
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.
