Ingredients Overview
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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterAlcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol and other additives. It has a low molecular weight and will evaporate quickly. This helps other ingredients become better absorbed and dry once applied.
Alcohol Denat. is volatile and may cause irritation. It helps draw out natural oils in skin and dry out your skin.
One study from 2005 found adding emollients to propanol-based sanitizer decreased irritation.
Alcohol is antibacterial by nature. This can help preserve products and increase their shelf life.
Other types of astringent alcohols include:
Learn more about Alcohol Denat.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.
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.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
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 GlycerinButylene 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.
We don't have a description for Methyl Methacrylate Crosspolymer.
Salicylic Acid (also known as beta hydroxy acid or BHA) is one of the most well-known ingredients for treating skin that struggles with blackheads and acne. It helps to exfoliate both the skin's surface and pores, and also acts as an anti-inflammatory agent.
This multitasking property makes it a great ingredient for cleaning out pores, controlling oil production, and reducing inflammation.
Unlike AHAs which are water soluble, Salicylic Acid is oil soluble. This means that it's able to exfoliate the inside of pores and reduce blackheads.
Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product.
It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing a Salicylic Acid into your routine.
In general, Salicylic Acid is a great ingredient for oily acne-prone skin.
While salicylic acid does not increase sun-sensitivity, we still recommend wearing SPF.

Learn more about Salicylic AcidAmmonium Polyacryloyldimethyl Taurate is a polymer made from ammonium salts. It helps add stability and texture to a product.
Ammonium Polyacryloyldimethyl Taurate is stable over a wide pH range. Due to its ability to absorb water, it can help thicken the texture of a product.
As an emulsion stabilizer, this ingredient is able to stabilize and mix the other ingredients. This creates a consistent texture.
Learn more about Ammonium Polyacryloyldimethyl TaurateNylon-12 is a polymer. It is derived from 12-aminododecanoic acid, an omega-amino fatty acid
According to a manufacturer, it is a talc substitute. Like talc, nylon-12 gives products a satin feel. The manufacturer also claims this ingredients does not block pores and has moderate oil absorption.
This ingredient may not be reef-safe.
Learn more about Nylon-12Dipropylene Glycol is a synthetically created stabilizer and solvent. It is a part of the glycol class in the alcohol family.
Dipropylene Glycol helps dissolve and evenly distribute ingredients. It also helps decrease viscosity and thin out texture.
As a masking agent, Dipropylene Glycol can be used to cover the smell of other ingredients. However, it does not have a scent.
Studies show Dipropylene Glycol is considered safe to use in skincare.

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.

Boswellia Serrata Extract is the extract of the whole plant, Boswellia serrata, Burseraceae.
AKA Indian Frankincense Extract
Hamamelis Virginiana Water is made used distilled parts of the witch hazel plant. The witch hazel plant is native to eastern North America.
The name 'Hamamelis Virginiana Water' refers to the distillation while the name 'Witch Hazel' is used when it is an active drug ingredient. Unless it is specified to be non-alcohol, many types of witch hazel are distilled in denatured alcohol.
Witch Hazel water is an astringent, anti-inflammatory, antioxidant, and antibacterial ingredient. The tannin in witch hazel has a drying effect when used on skin and constricts proteins. This helps minimize the look of large pores. The tannins present and the fragrance may be sensitizing. The catechins in witch hazel have anti-inflammatory properties while the gallic acid is antibacterial.
Indigenous groups have used witch hazel to help treat inflammation, which was then used by early settlers to North America.

At room temperature, T-Butyl Alcohol melts and has a similar smell to camphor.
This ingredient is derived from isobutane. It is the simplest form of a tertiary alcohol. Due to its chemical structure, it is more resistant to oxidation.
Learn more about T-Butyl AlcoholCamphor is a waxy solid with a strong scent. It is made using turpentine oil.
Camphor is used for medicinal purposes due to its cooling effect. In medicine, camphor is a common anti-inflammation ingredient.
It possesses antibacterial and antifungal properties.
One study found camphor to be a potential anti-wrinkle ingredient. This might be due to its ability to increase elastin and collagen production. Collagen and elastin are responsible for plump and youthful looking skin.
It is best to use cosmetics with a small amount of camphor under 11%. Using topical camphor may induce irritation and redness.
In the past, camphor was traditionally made by distilling the wood of the camphor tree.
Learn more about CamphorMenthol is a compound found in mint plants, such as peppermint. In its pure form, it is a clear crystalline substance.
Menthol is known for its cooling sensation; however, the cooling is actually from your skin being sensitized. Menthol can worsen rosacea. We recommend speaking with a professional if you have concerns.
Menthol also has antimicrobial properties.

Ginger root has antioxidant, anti-inflammation, and antimicrobial properties.
The antioxidant properties help protect your body from free-radicals. Free-radicals are molecules that may damage your skin cells. As a result, ginger may help slow down signs of aging such as hyperpigmentation and wrinkles.
Studies show ginger inhibits the enzyme that breaks down collagen. It also helps with:
Ginger has no negative side-effects and is safe to use for all skin types. (Be sure to patch test just in case you have a ginger allergy!)
Ginger originates from Southeast Asia but has spread throughout the world. It is now a common spice used in many cultures.

We don't have a description for Cinnamomum Cassia Bark Extract.
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.
Cinnamal is an aromatic aldehyde. It is naturally occurring in the spice known as cinnamon.
Cinnamal is a known EU allergen, meaning it may cause an allergic reaction when applied to the skin.
We don't have a description for Laminaria Saccharina Extract.
Zinc Sulfate is a type of sulfate.
Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.
Learn more about Sodium HydroxideCitric 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.
