Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Hyaluronic acid is naturally found in healthy skin. It is a humectant, meaning it draws moisture to your skin.
This ingredient helps hydrate, soothe, and protect the skin.
What makes hyaluronic acid so hydrating? It has the capacity to bind or hold large amounts of water.
Fun fact: It is already naturally found in our bodies, such as the fluids of our eyes and our joints.
Studies find this ingredient to have anti-inflammatory and anti-microbial properties. This can help speed up wound-healing.
Hyaluronic acid can be irritating if the molecule has a low-molecular weight, or if the molecules are small.
One study found low-molecular weight hyaluronic acid to be pro-inflammatory, meaning some people may experience irritation. This is because our bodies use hyaluronic acid in the wound-healing process to signal to our bodies, via irritation, that something needs healing.
The same study found high-molecular weight hyaluronic acid to be anti-inflammatory.
These are some other common types of Hyaluronic Acid:
Learn more about Hyaluronic AcidPanthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.
There are two forms of panthenol: D and L.
D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.
This ingredient is also referred to as pro-vitamin B5.

Some studies have shown this ingredient can promote wound healing with higher concentrations.
Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.

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 WaterEthylhexylglycerin (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.
Sodium 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:

This hydrates my skin very well and gives that “glass skin” look. It doesn’t feel sticky and absorbs quickly. But something in this is breaking me out, no idea which ingredient is the culprit. Gives me tiny pimples in different areas of my face each day I use it. I’m disappointed because it seems like a great product for those with sensitive acne prone skin like myself, but my skin just doesn’t Show more
This is so hydrating and great for my combination sensitive skin! It’s also way better than the isntree ultra low molecular toner in terms of hydration and results it provides. This toner did not make my face burn nor red in fact it calmed down my redness and provided me with a great amount of hydration, I also noticed how my makeup base was a lot more flawless than before. Not to mention this Show more
