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 WaterCaprylyl 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.
Learn more about Caprylyl GlycolSodium Hyaluronate Crosspolymer is a type of hyaluronic acid. In fact, it is modified version of hyaluronic acid.
The structure of Sodium Hyaluronate Crosspolymer allows it to stay in the skin's top layer for a longer period of time. This allows for even more hydration and humectant action than hyaluronic acid.
These are some other common types of Hyaluronic Acid:
Learn more about Sodium Hyaluronate CrosspolymerSodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:
Learn more about Sodium HyaluronateGlycerin 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 GlycerinEthylhexylglycerin (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.
Acetyl Hexapeptide-8 is a peptide. A common name for this peptide is Argireline.
Argireline has a similar function to botox; it prevents muscle movement and contractions slightly. By preventing muscles from moving, argireline also prohibits the formation of fine lines and wrinkles. However, research is lacking in proving this ingredient to be as effective as botox.
On the other hand, argireline tells our body to create more collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.

Learn more about Acetyl Hexapeptide-8Copper 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!
This ingredient helps 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.
On top of all this, Copper Tripeptide-1 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.

I've slept on peptides for way too long. Don't make the same mistake!
This product has made my skin look more youthful in a way I didn't know was possible, and has increased my skin's baseline level of hydration in a way that other hydrating products have not.
I love this serum! Copper peptides speed up the healing process of rosacea / eszema / damaged skin barrier etc.
It has also anti aging properties, its hydrates…it pretty much got rid of my “dehydration” within 2 days and calmed down my rosacea within 1 day.
it’s just an all rounder that I certainly implement in my skin routine all the time.
However, it’s important to note: copper peptides break Show more
