Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Water

What it does: Skin Conditioning, Solvent

Community Rating: Loved

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!

Decyl Glucoside

What it does: Cleansing, Emulsion Stabilising

Community Rating: Mixed

Decyl Glucoside is a glucose-based surfactant. Surfactants help clean the skin by trapping oil, sebum, and dirt to be washed away.

It is created by reacting glucose with the fatty acids from plants.

Decyl Glucoside also helps stabilize the ingredients in a product by preventing them from separating.

This ingredient is biodegradable and non-toxic. This ingredient is commonly found in baby shampoos.

Trisodium Ethylenediamine Disuccinate

What it does:

Community Rating: Liked

Trisodium Ethylenediamine Disuccinate is used to help stabilize a product.

Living Proof Perfect hair Day Shampoo contains this as ingredient number 24.

Sodium Benzoate

What it does: Masking, Preservative

Community Rating: Disliked

Sodium 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.

Sodium Benzoate 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.

Citric Acid

What it does: Buffering, Masking

Community Rating: Disliked

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.

Parfum

What it does: Masking, Perfuming

Community Rating: Very Disliked

Parfum is a catch-all term for an ingredient or more that is used to give aroma to products. Parfum, or fragrance, 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.

In the US, the alternative name for parfum is 'fragrance'. The term '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. One example is Calendula flower extract. Essential oil ingredients still impart a scent or 'fragrance'.

Depending on the blend, it can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Products use parfum often to give products a scent or cover up smells of different ingredients.

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.

Limonene

What it does: Perfuming, Solvent

Community Rating: Very Disliked

Limonene is a fragrance that adds scent and taste to a formulation.

It's found in the peel oil of citrus fruits and other plants such as lavender and eucalyptus. The scent of limonene is generally described as "sweet citrus".

Limonene acts as an antioxidant, meaning it helps neutralize free radicals.

When exposed to air, oxidized limonene may sensitize the skin. Because of this, limonene is often avoided by people with sensitive skin.

The term '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.
