Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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 WaterSodium C14-16 Olefin Sulfonate is a cleansing agent made from a mixture of long chain sulfonate salts. It can also help produce foam.
This ingredient may be drying. We recommend speaking with a professional if you have concerns.
This ingredient is an amino acid that helps build proteins and moisturizes skin. It is already present in our skin as our bodies produce them naturally.
Glycine already plays a role in helping keep our skin moisturized as amino acids transport moisture throughout our skin.
As collagen is made up of glycine and other amino acids, it is believed glycine may help our skin produce more collagen.
Learn more about GlycineCocamidopropyl Betaine is a fatty acid created by mixing similar compounds in coconut oil and dimethylaminopropylamine, a compound with two amino groups.
This ingredient 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 BetaineChances 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 ChlorideGlycerin 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 GlycerinSodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.
Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
It is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.

Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.
The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Parfum can also be used to mask or cover an unpleasant scent.
The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
Learn more about ParfumPolyquaternium-10 is an ammonium salt of hydroxyethylcellulose. It is a white and granular powder used as a film-former and anti-static agent.

You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.
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.
- It has mild preservative properties.
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Hydrolyzed Soy Protein is a vegan protein made to mimic hydrolyzed collagen. It is created from soy, or glycine soja.

Serine is an amino acid naturally found in our body. Our bodies use amino acids to create protein.
Amino-acids help give keep our skin hydrated. They play an important role in the skin barrier, which keeps the skin plump and firm.
Serine is a non-essential amino acid, meaning we don't need to obtain it from eating foods.
Learn more about SerineGlutamic Acid is an amino acid that is found in all living organisms. Our bodies use this to help nerve cells in the brain communicate with other cells.
In cosmetics, glutamic acid is a famous humectant. It draws water from the air to your skin, keeping your skin hydrated (like hyaluronic acid).
An in-vitro study from 2024 found glutamic acid to play a role in inhibiting inflammation and thus a potential skin-soothing ingredient.
Other studies show it to be have potential wound healing, skin barrier repair, and hair growth properties.
Glutamic acid has poor solubility in water and other solvents.
Learn more about Glutamic AcidAspartic Acid is an amino acid that our bodies produce naturally. It is an antioxidant.
Our body uses Aspartic Acid to help build collagen and elastin. It also plays a role in hydrating skin.
We don't have a description for Leucine yet.
Alanine is an amino acid and is already found in the human body. Our skin uses alanine to build collagen, elastin, and keratin.
Lysine is an essential amino acid. Your body is unable to produce it naturally and we mainly get lysine from food sources.
Our bodies use lysine for growth and tissue repair. The skin uses amino acids as a precursor for building protein, and therefore keratins, collagen and elastin.
Arginine is an amino acid that is important for human development. Your body uses is it to produce hair keratin and skin collagen.
As a cosmetic ingredient, Arginine has antioxidant properties and can also help repair damaged skin. This ingredient is derived either synthetically or from animals.
Arginine isn't fungal acne safe when used in the presence of other lipids (fats, fatty acids, oils, esters, etc). Oils and fats occur naturally within the skin, so take caution when using Arginine if you're prone to fungal acne.

A study from 2012 found tyrosine to show promising results in restoring skin volume.
Phenylalanine is an amino acid. It is a skin soothing and hydrating ingredient. Amino acids play a crucial role in wound healing and skin hydration.
This ingredient is also used to help even out skin tone due to its ability to disrupt the melanin production process.
Two structures of phenylalanine exist: L-phenylalanine and D-phenylalanine. L-phenylalanine is essential, this means our bodies cannot produce it naturally and we must get it from foods. Our bodies convert D-phenylalanine to neurotransmitters, and D-phenylalanine is found in our bodies naturally.
Some foods that contain L-phenylalanine include eggs, soybeans, beef, milk.
Learn more about PhenylalanineProline is an amino-acid. It helps moisturize the skin and plays an important role in creating proteins.
Our skin uses proline as one of the building blocks for producing collagen.
In medicine, proline is used as an osmoprotectant. This means it helps prevent oxidative degradation in other drugs.
Our bodies are able to produce proline naturally, but certain conditions may inhibit this production. In that case, proline can be obtained from eating egg whites, soy protein, dairy products, asparagus, mushrooms, and seaweed.
Learn more about ProlineThreonine is an amino-acid. It helps hydrate the skin and has antioxidant benefits.
Our skin uses threonine for creating collagen and elastin. Humans are not able to create threonine and must get it through eating foods such as fish, lentils, poultry, sesame seeds, and more.
Valine is an essential amino acid. It is used by our bodies for tissue repair and muscle growth.
An essential amino acid is one in which our bodies cannot naturally produce so we must get them through diet. Foods such as eggs, dairy, red meat, and fish contain valine.
This ingredient can either be derived from an animal product or be synthetically created.
Learn more about ValineIsoleucine is an amino acid that helps reinforce our skin barrier. This amino acid plays a role in creating protein for the body.
Fun fact: Isoleucine is found in meat, fish, dairy, legumes, and nuts.
Histidine is a semi-essential amino acid used by our bodies to create protein. It has humectant and skin conditioning properties.
Our bodies use histidine to create filaggrin - filaggrin is a structural protein that the skin uses in maintaining skin barrier.
One study found histidine and carnosine to be a dynamic duo for your skin:
Oral histidine has also been found to help with filaggrin-deficit skin disorders such as atopic dermatitis.
Why is it considered a semi-essential amino acid? This is because adults are able to create it but children must get it from their diet.
Learn more about HistidineCysteine is an amino acid found in our bodies. It becomes an antioxidant when converted into gluthatione.
Once it becomes gluthatione, it prevents oxidative damage to parts of our cell. Gluthatione has also been shown to protect our skin from UV-B induced damage.
Methionine is an essential amino acid. It is a conditioning agent and commonly found in both skin and hair products.
This amino acid is a precursor to glutathione, a powerful antioxidant.
