Ingredients Explained

These ingredients are found in both products.

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

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.

Glymed Plus Peptide Serum contains this as ingredient number 2.

COSRX The 6 Peptide Skin Booster Serum contains this as ingredient number 34.

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.

Glymed Plus Peptide Serum contains this as ingredient number 5.

COSRX The 6 Peptide Skin Booster Serum contains this as ingredient number 41.

Copper Tripeptide-1

What it does: Skin Conditioning

Community Rating: Loved

Copper Tripeptide-1 is a peptide naturally found in body fluids. Peptides are building blocks for protein.

Studies show this ingredient tells our body to create more collagen and elastin. Collagen is a protein that makes connective tissue. Elastin is the protein responsible for giving our skin elasticity. Our bodies start to slow down collagen and elastin production with age.

Boosting collagen and elastin production can help create a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin. It's a win-win situation!

Studies show this ingredient can help with scar healing. This is because it breaks down damaged collagen, the main component of scar tissue. It may also help with reducing sunspots, acne scars, and uneven skin tone.

This ingredient is also an antioxidant. Antioxidants help the body fight off free-radicals. Free radicals are molecules that damage our cells, such as pollution and tobacco smoke.

More benefits: Copper Tripeptide-1 helps maintain tissues in blood vessels and promote natural hyaluronic acid in skin.

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.

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: Loved

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.

Pentylene Glycol

What it does: Skin Conditioning, Solvent

Community Rating: Mixed

Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.

The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.

This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.

Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.

Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
