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 WaterMyristic Acid is a saturated fatty acid. It is naturally found in milk fat. Other sources include palm oil, coconut oil, and butter fat.
Myristic Acid is an emulsifer and cleanser. As an emulsifer, it stabilizes a product by preventing ingredients from separating. Myristic Acid helps clean your skin by acting as a surfactant. It tends to gather oil and dirt on your skin to be easily rinsed away.
One study from 2021 found Myristic Acid to have anti-inflammatory properties.
Learn more about Myristic AcidChances are, you eat sodium chloride every day. Sodium Chloride is also known as table salt.
This ingredient has many purposes in skincare: thickener, emulsifier, and exfoliator.
You'll most likely find this ingredient in cleansers where it is used to create a gel-like texture. As an emulsifier, it also prevents ingredients from separating.
There is much debate on whether this ingredient is comedogenic. The short answer - comedogenic ratings don't tell the whole story. Learn more about comegodenic ratings here.
The concensus about this ingredient causing acne seems to be divided. Research is needed to understand if this ingredient does cause acne.
Scrubs may use salt as the primary exfoliating ingredient.
Learn more about Sodium ChlorideEthyl Hexanediol is an aliphatic alcohol. It is a solvent.
Solvents are used to keep ingredients together in a product. They can help dissolve ingredients to stable bases or help evenly distribute ingredients throughout the product.
Cocamidopropyl Betaine is a fatty acid created by mixing similar compounds in coconut oil and dimethylaminopropylamine. Dimethylaminopropylamine is a diamine, an amine with two amino groups.
Cocamidopropyl Betaine is a surfactant and cleanser. It helps gather the dirt, pollutants, and other impurities in your skin to be washed away. It also helps thicken a product and make the texture more creamy.
Being created from coconut oil means Cocamidopropyl Betaine is hydrating for the skin.
While Cocamidopropyl Betaine was believed to be an allergen, a study from 2012 disproved this. It found two compounds in unpure Cocamidopropyl Betaine to be the irritants: aminoamide and 3-dimethylaminopropylamine. High-grade and pure Cocamidopropyl Betaine did not induce allergic reactions during this study.
Learn more about Cocamidopropyl BetaineCitrus Limon Fruit Oil comes from the lemon fruit.
Lemons contains antioxidants, which may help with anti-aging. They are also rich in citric acid, an AHA. And of course, lemons are rich in Vitamin C. Vitamin C helps with skin-brightening and increasing collagen production.
The acidity of lemons may work as an astringent for acne. Astringents constrict the pores.
Learn more about Citrus Limon Fruit OilSodium Methyl Cocoyl Taurate isn't fungal acne safe.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.
Stearic 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 AcidPeg-60 Hydrogenated Castor Oil comes from hydrogenated castor oil. It is a solubilizer and emulsifier.
As a solubilizer, it helps dissolve ingredients into a water-based version. It is also an emulsifer. Emulsifier help prevent oils and water from separating. Both these properties help create evenly-spread and uniform products.
Basically, Peg-60 Hydrogenated Castor Oil helps hold ingredients together.
Learn more about Peg-60 Hydrogenated Castor OilPolysorbate 80 is a surfactant and emulsifier. It is used to keep ingredients together, and prevent oils and waters from separating.
It is made from polyethoxylated sorbitan and oleic acid. This ingredient can be found in cosmetics, foods, and medicine. It is water-soluble.
Polysorbate 80 may not be fungal acne safe.
Learn more about Polysorbate 80Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
Learn more about Caprylyl GlycolGlycerin 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 GlycerinPotassium hydroxide is commonly known as caustic potash. It is used to fix the pH of a product or as a cleaning agent in soap. In cleansers, it is used for the saponification of oils.
Sapnification is the process of creating fatty acid metal salts from triglycerides and a strong base. During this process, Potassium Hydroxide is used up and is not present in the final product.
Using high concentrations of Potassium Hydroxide have shown to irritate the skin.
Learn more about Potassium HydroxideSalicylic 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 AcidLauric Acid is a fatty acid or lipid. About half of fatty acids in coconut oil is lauric acid.
This ingredient helps hydrate and sooth skin. As a humectant, it helps trap moisture. It also aids in cleaning and enhancing the texture of products.
Emerging studies show Lauric Acid to have antimicrobial and anti-inflammatory properties. The antimicrobial property helps strengthen the skin barrier by fighting off bad bacteria.
Lauric acid may not be Malassezia folliculitis, or fungal acne, safe.
Learn more about Lauric AcidButylene 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.
Salix Alba Bark Water is created by distilling parts from the white willow tree. The white willow tree is native to Europe and Central Asia.
Salix Alba Bark has often been described as salicylic acid's cousin. This is due to the salicin it contains. However, studies are limited showing salix alba bark to be an effective salicylic acid alternative.
Salicin does have anti-inflammatory and antioxidant properties. It has shown to decrease the formation of inflammatory mediators, such as tumor necrosis factor-α and nuclear factor-kappa B. Salicin also has a mildly exfoliating effect on the skin.
As an astringent, salix alba bark water helps tighten the skin by drawing water out. This helps reduce the appearance of large pores.
Learn more about Salix Alba Bark Water1,2-Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant.
In products that are water-based, this ingredient can help stabilize perfumes and fragrances. It can also help make the texture of products softer and more smooth.
Disodium EDTA plays a role in making products more stable by aiding other preservatives.
It is a chelating agent, meaning it neutralizes metal ions that may be found in a product.
Disodium EDTA is a salt of edetic acid and is found to be safe in cosmetic ingredients.
Learn more about Disodium EDTAGlycol Distearate serves as a pearlizing or opacifying agent in cosmetic products.
It's often included in cleansers and haircare products to give them a lustrous or shimmering appearance.
It is derived from stearic acid, a natural fatty acid commonly found in vegetable oils and animal fats.
Glycol Distearate isn't fungal acne safe.
Learn more about Glycol DistearateThis tea tree oil comes from the leaves of the Tea Tree plant. Tea tree oil has antioxidant, anti-inflammatory, and antimicrobial properties.
According to the book Journal of Profiles of Drug Substances, tea tree helps in reducing acne-causing bacteria such as Propionibacterium acnes. This is due to the Terpinen components of tea tree oil.
Tea tree may cause sensitivity and irritation for some people. This oil naturally contains fragrance such as linalool and limonene.
However, research shows irritation usually occurs when using pure tea tree oil and not in cosmetic products.
Tea tree oil was found to help relieve the symptoms of psoriasis in one study.
Tea tree oil is toxic when ingested. Another study showed it to caused damage to the nervous system of dogs and cats when applied to their skin or given orally.
Learn more about Melaleuca Alternifolia Leaf OilCitric 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.

I used to think it was good because of how it really goes DEEP into cleaning your skin, it feels like it’s been scraped out. It’s good if you haven’t washed your face in a week, other than that it’s really bad. And that’s coming from someone who has oily skin and uses Paula’s choice BHA every other day. There are so many better cleansing products than this, I highly advise getting the Etude house foam 6.5 whip cleaner instead and using an exfoliant alongside it. One thing I do like about this cleanser is its consistency, I always loved how it would squirt out but on the downside was it’s drying out of skin. It never “ruined” my skin per se, but there are a lot better products than this for daily cleansing. If you want your skin to feel EXTREMELY scraped of all oils and its essence, sure use this.
Okay.. but NO.. not safe for fungal acne.
