Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
BHT is a synthetic antioxidant and preservative.
As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.
As a preservative, it is used to stabilize products and prevent them from degrading. Specifically, BHT prevents degradation from oxidation.
The concerns related to BHT come from oral studies; this ingredient is currently allowed for use by both the FDA and EU.
However, it was recently restricted for use in the UK as of April 2024.
Learn more about BHTCI 19140 is also known as Tartrazine. Tartrazine is a synthetic dye used in cosmetics, foods, and medicine to add a yellow color.
Tartrazine is created from petroleum and is water-soluble.
Some people may experience allergies from this dye, especially asthmatics and those with an aspirin intolerance.
Learn more about CI 19140Ci 42090 is a synthetic dye created from petroleum. It is used to give a bright blue color to cosmetics, medicine, and food.
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.
This synthetic powder is used to add a pearly/white color in cosmetics.
Ci 77288 is used to add green pigment to products.
We don't have a description for CI 77289 yet.
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 77510This ingredient is used to add a violet color to cosmetics.
It is created by reacting phosphoric acid, ammonium dihydrogen orthophosphate, and manganese dioxide.
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 77891Disteardimonium Hectorite comes from the clay mineral named hectorite. It is used to add thickness to a product.
It can also help stabilize a product by helping to disperse other ingredients.
Hectorite is a rare, white clay mineral.

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.

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 IsododecaneLecithin is a term for a group of substances found in the cell membranes of plants, animals, and humans. They are made up of phospholipids.
Thanks to its amphiphilic structure (water-loving head and oil-loving tail), it is a true multitasker:
It plays well with most ingredients and is typically used at 0.1-1%. However, concentrations up to 50% have been reported in moisturizers.
Learn more about LecithinMethicone is a type of silicone and is a simpler form of dimethicone.
Silicones are used to enhance the texture of products and have emollient properties. Methicone is used to give products a silky texture and improves spreadability.
Mica 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 MicaPhenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!).
It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome.
On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive.
Another perk of this ingredient is that it stays functional across a wide pH range (3-10).
You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own.
Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU.
Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages.
Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon.
Learn more about PhenoxyethanolThis silicone is an emollient. Emollients create a thin film on the skin to prevent moisture from escaping.
It is not soluble in water and helps increase water-resistance in products.
According to a manufacturer, it can blend seamlessly with silicone oils, such as Cyclopentasiloxane.
