Dimethicone Crosspolymer is a silicone created by modifying dimethicone with hydrocarbon side chains. Due to its large size, it does not penetrate skin. It is considered non-occlusive.

Dimethicone Crosspolymer is used to stabilize and thicken products. It also helps give products a silky feel.

This ingredient is a silicone used to improve the texture of products and absorb oil. It does not get absorbed into the skin.

Like other silicones, Dimethicone/Vinyl Dimethicone Crosspolymer helps condition the skin by creating a barrier. In this sense, it can act as an emollient and trap moisture in.

Butyloctyl Salicylate is similar to octisalate. It a photostabilizer, SPF booster, emollient and solvent. Its main purpose is to evenly spread out ingredients.

This ingredient is a common sunscreen ingredient carrier and photostabilizer. According to a manufacturer, it is suitable for carrying micro Titanium Dioxide, Zinc Oxide, and pigments.

Glyceryl Isostearate is a mixture made from glycerin and isostearic acid.

It is an emollient, meaning it helps keep your skin hydrated and soft. This ingredient is also used to make the texture of a product thicker.

Polyester-8 is not reef safe.

Polysilicone-15 is a chemical UV filter that absorbs UV-B rays. It is a photostable ingredient often used to boost SPF factor and protect products from UV-induced deterioration.

Due to regulation loopholes, this ingredient is not required to be labeled as an active chemical filter like other UV ingredients. This is why you'll likely find this ingredient in mineral sunscreens from the US.

Ceramide AP is a type of Ceramide.

Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. Having a strong skin barrier leads to more firm and hydrated skin.

Ceramide EOP is a type of Ceramide.

EOP stands for a linked Ester fatty acid, a linked Omega hydroxy fatty acid, and the Phytosphingosine base.

Ceramide EOS is a type of Ceramide.

Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. They are known for their ability to hold water and thus are a great ingredient for dry skin.

Ceramide NP is a type of ceramide.

Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. They are known for their ability to hold water and thus are a great ingredient for dry skin.

Ceramide NS is a type of Ceramide. Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. They are known for their ability to hold water and thus are a great ingredient for dry skin.

Tetrahexyldecyl Ascorbate (THD) is a stable and oil-soluble form of Vitamin C.

THD is special in that it has the ability to travel deeper into skin than traditional ascorbic acid while maintaining the same skin benefits (double win!).

Camellia Sinensis Leaf Extract is derived from the leaves of the tea plant. Black tea, green tea, and oolong tea are all harvested from this plant.

This ingredient has many skin benefits:

Punica Granatum extract comes from the pomegranate fruit.

Pomegranates are rich in fatty acids, including an unsaturated fatty acid by the name of Punicic acid. Other components of pomegranates include Vitamin E, and Vitamin C.

Vaccinium Macrocarpon Fruit Extract comes from the cranberry fruit. Vaccinium Macrocarpon is the North American species of cranberries native to eastern Canada.

As an astringent, cranberry extract helps tighten the pores by constricting the cells.

Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.

One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.

Ascorbyl Palmitate is created by combining pure Vitamin C and palmitic acid. It is an antioxidant and helps reduce hyperpigmentation.

This ingredient is a more stable version of Vitamin C, meaning it does not disintegrate as quickly when exposed to sunlight. However, studies show it does not penetrate skin as well as pure Vitamin C.

Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.

Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

Behenic Acid is a fatty acid and has moisturizing properties.

It is naturally occuring in the Moringa oleifera tree, rapeseed oil, and peanut oil.

Cholesterol is a class of organic molecules called lipids. It helps hydrate your skin and is essential to having a healthy skin barrier.

Our skin naturally contains cholesterol in the outermost layer. Besides cholesterol, it also contains ceramides and fatty acids. Cholesterol makes up about 1/4 of your skin's outer layer and barrier. Your skin barrier is responsible for keeping allergens and microbes out. Having a healthy skin barrier is also responsible for keeping your skin firm and plump.

Polyhydroxystearic Acid is a soft wax made from castor oil.

It is is a texture thickener, emulsifier, and film-former. Emulsifiers prevent ingredients from separating, such as oils and waters.

Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.

Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.

Ceteareth-25 comes from Cetearyl Alcohol. (And Cetearyl Alcohol is created from cetyl alcohol and stearyl alcohol.

This ingredient is a fatty alcohol used as an emulsifier and surfactant. As an emulsifier, it helps oil mix with water.

Cetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.

Its main roles are:

PEG/PPG-18/18 Dimethicone is a type of silicone.

This ceramide helps condition and moisturize skin.

It is created by reacting caproic acid and phytosphingosine, two fatty acids.

We don't have a description for Caprooyl Sphingosine yet.

Triethoxycaprylylsilane is a silicone used to bind and stabilize ingredients.

As an emulsifier, it helps prevent ingredients from separating. This can help elongate the shelf life of products.

This 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.

Titanium dioxide is known for its UVA and UVB protection properties. It is non-comedogenic and non-irritating. Titanium Dioxide is a physical sunscreen. Physical sunscreens reflect light and prevent it from reaching your skin.

Protecting your skin against UV radiation can prevent the signs of aging. Sun damage is associated with fine-lines, wrinkles, loss of firmness, and hyperpigmentation. Titanium dioxide can help prevent premature aging.

Zinc Oxide is a mineral broad-spectrum UV filter; it is the broadest UVA and UVB reflector approved by the FDA. While it is most commonly man-made for cosmetics, it can naturally occur in zincite, a rare mineral.

Today, traditional and nano-sized zinc oxide can be found in beauty products. Nano-sized zinc oxide can enhance a product's UV protection. While it is not believed to have a negative effect on skin, nano-zinc oxide may be harmful to coral reefs - though the verdict is not entirely out on this one.
