Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Cyclopentasiloxane, 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.
Learn more about CyclopentasiloxanePolyethylene is a synthetic ingredient that helps the skin retain moisture. It is a polymer.
Polyethylene 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.
Disteardimonium 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.
Learn more about Disteardimonium HectoriteThis 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.
Learn more about TrimethylsiloxysilicateLecithin is a term for a group of substances found in the cell membranes of plants, animals, and humans. They are made up of mixture of phospholipids.
This ingredient has emollient and emulsifying properties.
As an emollient, lecithen helps soften the skin and creates a barrier to keep moisture in.
As an emulsifier, it also helps prevent water and oil ingredients from separating. Lecithin can also help ingredients be better absorbed by the skin.
This is because the phospholipids in lecithin produce liposomes. Liposomes help other ingredients get through the skin barrier.
Depending on the source of this ingredient, lecithin may not be fungal acne safe. This is because some sources of lecithin come from soybean oil, which may feed the malassezia yeast that feeds fungal acne.
We recommend reaching out to the brand you are purchasing from to inquire about the source of their lecithin.

Propylene Carbonate is commonly used in makeup and with clay, such as montmorillonite or bentonite.
Studies show this ingredient to be safe for cosmetics. When it is undiluted, it can cause skin irritation. (It is always diluted in skincare and makeup). This ingredient is water-soluble.
Propylene Carbonate is created from propylene glycol and carbonic acid.
Learn more about Propylene CarbonateMica refers to a group of silicate minerals. Mica crystals are easily split to give products a shimmer. These crystals are able to reflect light to temporarily give your skin a glowy look.
Mica is found to be safe. 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.
Mica can be naturally found throughout the world. However, some sources of mica may be controversial. In 2016, mica mined in the Jharkhand state in India was found to be using child labor. However, companies are able to source ethical mica affiliated with international organizations that monitor the mica supply chain.
