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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!Learn more about Water
Niacinamide has emerged as an all-star ingredient due to its many benefits.
It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.Learn more about Niacinamide
Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.Learn more about Glycerin
Propanediol helps absorb ingredients into your skin, boosting their benefits. It can act as an emollient, making your skin softer. Propanediol can help products last longer by boosting the properties of preservatives within the formulation.
Propanediol is not likely to cause sensitivity and considered safe to use.
It is derived from corn or petroleum with a clear color and no scent.Learn more about Propanediol
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
- It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
- It is a humectant, which means that it helps attract moisture into the skin.
- It helps improve product application.
Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and 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.
This is a synthetic polymer. It helps improve the texture of products by adding thickness and gel-like feel.
It is also an emulsifer, meaning it prevents ingredients such as oil and water from separating. It also helps evenly disperse other ingredients.
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.
Hydroxyethylcellulose helps stabilize products by preventing ingredients from separating. It can also help thicken the texture of a product.
This ingredient can also be found in pill medicines to help our bodies digest other ingredients.Learn more about Hydroxyethylcellulose
Phospholipids are naturally found in our skin as they are the main component of cell membranes. Phospholipids have humectant, emollient, antioxidant properties.
The phospholipids in our skin can be naturally depleted. Replenishing the phospholipids in our skin can help hydrate your skin. Due to their hygroscopic nature, they act as humectants and emollients. Humectants draw moisture from the air to your skin, while emollients help trap moisture in. This ingredient is non-occlusive.
Studies show phospholipids display antioxidant activity and may help with reducing the signs of aging.
Phospholipids are complex lipids that contain glycerin, two fatty acids, and a phosphate group. Some foods that contain phospholipids include soybeans and milk. The phospholipids found in soy come from Lecithin. This ingredient can also be synthetically created.

Squalane is an emollient that helps the skin hold onto moisture. It's an oily liquid that occurs naturally in certain types of fish and plant oils.
Because squalane boosts hydration in the skin, it also comes with plenty of benefits: it is an antioxidant and can help fight free radicals and skin damage. Squalane is also found to have a detoxifying effect when applied.
Squalane comes from squalene, which occurs naturally within the sebum of our skin. It is one of the oils our skin produces to keep itself hydrated. Squalane is the hydrogenated version of squalene and has a longer shelf life.
Research shows that squalane is non-irritating (even at 100% concentration).
In general, it's a fantastic ingredient. It does a great job at hydrating the skin, and it's suitable for those with sensitive skin.
The source of squalane may impact malassezia / fungal acne. This is because olive oil derived squalane can contain impurities such as fatty acids and plant waxes. Sugarcane derived squalane is recommended for anyone with malassezia concerns.
Is squalane vegan?
This depends on the source. Squalane can be derived from both plants and animals. Most squalane used in skincare comes from plants.
Please note: the source of squalane is only known if disclosed by the brand. We recommend reaching out to the brand if you have any questions about their squalane.

Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.Learn more about Xanthan Gum
Glycine Soja Oil comes from the soybean. Glycine Soja is native to eastern Asia.
As an emollient, the fatty acids in soybean oil helps keep your skin soft and hydrated. It does so by creating a film on top that traps moisture in.
Soybean oil is also rich in vitamin E, a potent antioxidant. Vitamin E is also anti-inflammatory and provides a soothing effect.
Studies show soy may help fade hyperpigmentation from UVB. It does so by disrupting the melanin process from UVB induced skin inflammation.
This ingredient may not be malassezia folliculitis, or fungal-acne, safe.
Soybeans are rich in proteins and are part of the legume family. Foods made with soybeans include tofu, soymilk, edamame, miso, and soy sauce.Learn more about Glycine Soja Oil
Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.
Some studies have shown this ingredient can promote wound healing with higher concentrations.
Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.Learn more about Allantoin
Sodium Phytate is the synthetic salt form of phytic acid. Phytic acid is an antioxidant and can be found in plant seeds.
Sodium Phytate is a chelating agent. Chelating agents help prevent metals from binding to water. This helps stabilize the ingredients and the product.
Polysorbate 60 is used to help stabilize products. It is a surfactant and emulsifier. These properties help keep ingredients together in a product. Surfactants help reduce surface tension between ingredients with different states, such as liquids and solids. Emulsifiers help prevent oils and waters from separating.
Polysorbate 60 is sorbitol-based and created from the ethoxylation of sorbitan. Ethoxylation is a chemical reaction used to add ethylene oxide. Sorbitan is a the dehydrated version of sorbitol, a sugar found in fruits.
In this case, the 60 comes from reacting 60 units of ethylene oxide with sorbitan.
Polysorbates are commonly used in medicine and foods.Learn more about Polysorbate 60
Panthenol (also referred to as pro-vitamin B5) is a common ingredient that helps hydrate and soothe the skin.
lt is a humectant, meaning that it helps the skin attract and retain moisture.

Leuconostoc/Radish Root Ferment Filtrate is a natural preservative. It comes from fermenting radish roots with a bacteria called leuconostoc. Leuconostoc comes from lactic acid. This bacteria is used to make the traditional Korean side-dish, kimchi. It is also used to make sourdough bread (both incredibly yummy foods).
Leuconostoc/Radish Root Ferment Filtrate has antimicrobial properties and helps prevent the growth of bacteria in a product.
It is believed the preservation property comes from salicylic acid and ammonium salt, neither of which are involved in the fermentation process.Learn more about Leuconostoc/Radish Root Ferment Filtrate
As an emulsifier, Sorbitan Isostearate prevents oils and water from separating.
Due to its isostearic acid base, it may not be safe for Malassezia or fungal acne.Learn more about Sorbitan Isostearate
Glycine Soja Sterols is derived from the soybean plant. Sterols are an organic compound and technically an alcohol.
Unlike solvent alcohols, glycine soja sterols have emollient properties and help hydrate the skin.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
Sterols can be found in plants, animals, and fungi.Learn more about Glycine Soja Sterols
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.
