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 WaterAlcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol with other additives.
This ingredient gets a bad rep because it is irritating and drying - mostly due to its astringent property. Astringents draw out natural oils in tissue, constricting pores and leaving your skin dried out.
However, alcohol denat. is not all that bad.
Due to its low molecular weight, alcohol denat. tends to evaporate quickly. One study on pig skin found half of applied alcohol evaporated in 10 seconds and less than 3% stayed on skin.
This also helps other ingredients become better absorbed upon application.
Studies are conflicted about whether this ingredient causes skin dehydration. One study from 2005 found adding emollients to propanol-based sanitizer decreased skin dryness and irritation. Another study found irritation only occurs if your skin is already damaged.
Small amounts of alcohol are generally tolerated by oily skin or people who live in humid environments.
The rule of thumb is if this alcohol is near the end of an ingredients list, it will probably not affect your skin much.
Also...
This ingredient has antimicrobial and solvent properties.
The antimicrobial property helps preserve products and increase their shelf life. As a solvent, it helps dissolve other ingredients.
Other types of astringent alcohols include:

As a solvent, Triethylhexanoin helps dissolve ingredients to stable bases or help evenly distribute ingredients throughout the product.
It is also an emollient and helps condition the skin.
Learn more about TriethylhexanoinDimethicone is a type of synthetic silicone created from natural materials such as quartz.
What it does:
Dimethicone comes in different viscosities:
Depending on the viscosity, dimethicone has different properties.
Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.
This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.
Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.
Learn more about DimethiconePentaerythrityl Tetraethylhexanoate is an emollient that helps make your skin smooth and hydrated. It specializes in creating a non-oily and "wet" feeling on skin.
This ingredient comes from isostearic acid, a saturated fatty acid. It is a synthetic ingredient.
Diphenylsiloxy Phenyl Trimethicone is a type of silicone.
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.

Extract from Betula Alba tree can help sooth and protect the skin. Betula Alba contains tannins and triterpenes. Tannins are an astringent and may help reduce pore size. Tannins are also antioxidants. Triterpenes have been shown to help heal wounds.
Betula Alba Bark Extract may also be used to add scent to a product.
Learn more about Betula Alba Bark ExtractWe don't have a description for Mesua Ferrea Flower Extract yet.
Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

- 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.
BHT is a synthetic antioxidant and preservative.
As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.
As a preservative, it is used to stabilize products and prevent them from degrading. Specifically, BHT prevents degradation from oxidation.
The concerns related to BHT come from oral studies; this ingredient is currently allowed for use by both the FDA and EU.
However, it was recently restricted for use in the UK as of April 2024.

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
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 even out skin tone.
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.
Read more about some other popular AHA's here:
Learn more about Citric AcidSodium Citrate is the sodium salts of citric acid. In skincare, it is used to alter pH levels and acts as a preservative.
Its main functions are to maintain the pH of a product and neutralize metal ions.
The acidity of our skin is maintained by our glands and skin biome; normal pH level of skin is slightly acidic (~4.75-5.5).
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.
Learn more about Sodium CitrateParaffinum Liquidum is also known as liquid paraffin. It is a type of highly refined mineral oil.
Like other oils, Paraffinum Liquidum has emollient properties. Emollients help soothe and soften the skin. By creating a barrier to trap moisture within, emollients help keep your skin hydrated.
Paraffinum Liquidum does not irritate the skin and is non-comedogenic.
Learn more about Paraffinum LiquidumChances 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 ChlorideHydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.
In one study, Hydrogenated Polyisobutene showed better skin hydration levels than Caprylic/Capric Triglyceride. As an emollient, it helps keep your skin soft and hydrated by trapping moisture in.
Hydrogenated Polyisobutene is often used as a mineral oil replacement.
Learn more about Hydrogenated PolyisobutenePhenoxyethanol 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.
Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.
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.
