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!

Glycerin

What it does: Humectant, Skin Conditioning, Skin Protecting, Solvent

Community Rating: Loved

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.

Glycine

What it does: Buffering, Skin Conditioning

Community Rating: Liked

Glycine is an amino acid that helps build proteins. It is already present in our skin as our bodies produce them naturally.

Glycine helps keep skin hydrated and reduce signs of aging. Amino acids help transport moisture throughout our skin; glycine already plays a role in helping keep our skin moisturized.

As collagen is made up of glycine and other amino acids, it is believed Glycine may help our skin produce more collagen. Collagen helps keep skin plump and firm.

Butylene Glycol

What it does: Humectant, Masking, Skin Conditioning, Solvent

Community Rating: Mixed

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.

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.

MartiDerm Platinum Neck-Line Correct Serum contains this as ingredient number 11.

The Ordinary "Buffet" contains this as ingredient number 37.

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.

Ethylhexylglycerin

What it does: Skin Conditioning

Community Rating: Mixed

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.

Caprylyl Glycol

What it does: Emollient, Humectant, Skin Conditioning

Community Rating: Liked

Caprylyl 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.

Phenoxyethanol

What it does: Preservative

Community Rating: Very Disliked

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.

MartiDerm Platinum Neck-Line Correct Serum contains this as ingredient number 42.

The Ordinary "Buffet" contains this as ingredient number 50.

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.
