Ingredients Explained
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.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterSynthetic beeswax is created to be identical in structure to beeswax. It possesses the same occlusive and emulsion properties.
A blend of fatty acid esters, fatty acids, and alcohols are used to create synthetic beeswax. Whether or not this ingredient is vegan depends on the source. Sometimes, lanolin is used for its creation.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
Learn more about Synthetic BeeswaxSynthetic Wax is created from fossil fuels such as natural gas. It is used to enhance texture, adjust pH, and as an occlusive.
It may also be used as an abrasive ingredient to exfoliate the skin.
Synthetic Wax may not be fungal acne safe.
Learn more about Synthetic WaxThis plant-based protein comes from peas.
According to the manufacturer, this peptide is created from the process of hydrolysis, or the process of breaking down chemical compounds with water. They claim this ingredient has antioxidant, anti-aging, and hydrating benefits for both skin and hair.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Learn more about Butylene GlycolGlyceryl Stearate is a mix of glycerin and stearic acid.
It is used to stabilize the mixing of water and oil ingredients. By preventing these ingredients from separating, it can help elongate shelf life. It can also help thicken the product's texture.
As an emollient, it helps soften skin and supports barrier-replenishing ingredients.
In cosmetics, Glyceryl Stearate is often made from vegetable oils or synthetically produced.
This ingredient may not be fungal-acne safe
Fun fact: The human body also creates Glyceryl Stearate naturally.
Learn more about Glyceryl StearateOryza Sativa Bran Wax is wax from the outer layer of a rice kernel. It has moisturizing properties due to its polysaccharides and omega-3 fatty acids content.
This ingredient is a byproduct of milling rice, or the operation to produce a whole grain rice product.
Palmitic Acid is a fatty acid naturally found in our skin and in many plant and animal sources. In cosmetics, it is usually derived from palm oil. It serves many purposes in skincare, acting as a cleanser, emollient, and emulsifier.
As an emollient, palmitic acid helps soften and smooth the skin by preventing water loss. In cleansers, it helps remove oil and dirt while creating foam.
Its emulsifying properties help stabilize products by keeping water and oil-based ingredients from separating.
This may not be suitable for fungal acne-prone skin, as fatty acids like this can sometimes trigger breakouts in sensitive individuals.
Learn more about Palmitic AcidPTFE is a form of PFAS, or "Per- and polyfluoroalkyl substances". This ingredient has been used in commercial applications since the 1940's.
In cosmetics, PTFE is most commonly used as bulking agents, to improve consistency, or to improve texture.
PFAS compounds are currently under scrutiny due to possible health risks. This is mostly due to one type of PFAS: PFOA.
PFOA is no longer used in cosmetics and is highly restricted in many countries.
Today, PFAS are used widely in the medical field. They often play an important role in medical equipment such as catheters and medical implants.
In 2018, the Expert Panel for Cosmetic Ingredient Safety found PTFE to be safe for use in cosmetics and personal care productions.
This ingredient is commonly found in mascara (up to 13%) and hair bleach (up to 2.4%). Studies show this ingredient does not cause skin or eye irritation.
The EU allows PTFE to be used in cosmetics without restrictions.
All federal agencies do state further research about PFAS in cosmetics is needed.
Whether you choose to use this ingredient is a personal choice. We recommend adding this ingredient to your liked or disliked list so you can be notified anytime a product contains this ingredient.
Learn more about PtfeStearic Acid is a fatty acid. It is an emollient, emulsifier, and texture enhancer.
As an emollient, stearic acid helps soften skin. It aids the skin's protective barrier by preventing water loss. It also provides a gentle cleansing effect without stripping away natural oils.
Stearic acid may also be used to enhance the texture of products. It can add volume and stabilize ingredients such as water and oil. This can help water and oil ingredients from separating.
Sources of stearic acid include animal or vegetable fats/oils such as coconut or shea. It can be naturally found in butter, cocoa butter, shea butter, vegetable fats, and animal tallow.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
Learn more about Stearic AcidTromethamine helps balance the pH and improve the texture of a product. It is synthetically created.
As an emulsifier, Tromethamine prevents oil and water ingredients from separating. This helps stabilize the product and elongate a product's shelf life. Tromethamine also makes a product thicker.
Tromethamine helps balance the pH level of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.
Oral Tromethanmine is an anti-inflammatory drug but plays the role of masking, adding fragrance, and/or balancing pH in skincare.

Learn more about PolybutenePvp is a water-soluble synthetic polymer and common hairstyling ingredient. It is a film-forming ingredient and used to "hold" specific shapes of hair.
Pvp is less effective in high-humidity. It tends to draw moisture, but this moisture dismantles the structure and "hold".
Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.
There are two forms of panthenol: D and L.
D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.
This ingredient is also referred to as pro-vitamin B5.
Learn more about PanthenolPhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Hydroxyethylcellulose is used to improve the texture of products. It is created from a chemical reaction involving ethylene oxide and alkali-cellulose. Cellulose is a sugar found in plant cell walls and help give plants structure.

It is a chelating agent and used to prevent metal ions from binding to other ingredients. This helps keep the product and ingredients stable.
Tetrasodium EDTA comes as a white solid and is soluble in water.
Linoleic Acid is also known as Vitamin F. It is a fatty acid with emollient and skin conditioning properties. Our top layer of skin, or epidermis, contains high amounts of linoleic acid naturally.
Your body uses linoleic acid to build ceramides and prostaglandins. Ceramides keep your skin's barrier hydrated and strong while prosaglandins help control inflammation and healing. Needless to say, linoleic acid is crucial for having a strong skin barrier.
One study found applying linoleic acid rich sunflower oil to be more effective at repairing the skin barrier than oleic rich olive oil.
Linoleic acid is an essential fatty acid, meaning our bodies cannot create it on its own. We need to get linoleic acid through foods such as nuts and vegetable oils.
Acne-prone skin tends to have linoleic acid and high levels of oleic acid.
Linoleic acid can also help treat acne by softening sebum to prevent clogged pores. Another study found using 2.5% linoleic acid gel for 4 weeks showed a 25% reduction in small comedones.
This ingredient can also help lighten hyperpigmentation or sun spots by disrupting the melanin production process. It also helps your skin shed melanin pigment from your skin caused by UV exposure.
Due to its role in the production of the fatty acid prostaglandin, linoleic acid can also help reduce inflammation and support wound healing.
Linoleic acid is not always fungal-acne safe; it may trigger flare-ups in sensitive individuals.
